FEATURES

Your RadioShack PRO-91 150-Channel Handheld

Trunking Scanner is one of a new generation of scan-

ners designed to track Motorola Type I and Type II

(such as Smartnet and Privacy Plus) and hybrid ana-

log trunking systems, which are extensively used in

many 800 MHz communicat ion systems.

Trunking communications systems let a large group of

2-way radio users (or even different groups of 2-way ra-

dio users) efficiently use a large range of frequencies.

Instead of selecting a specific frequency for a transmis

sion, the user sim ply selec ts a talk g r ou p. The t run ki ng

system automatically transmits the call on the first avail-

able frequency, and also sen ds (on a dif ferent frequen-

cy called a data channel) a code that uniquely identifies

that transmission.

Since the trun king sys tem m ight send a c all an d its re

sponse on di fferent fr eq ue ncies, it is difficult to l ist e n t o

trunked co mmunicat ions using a reg ular scanne r. The

PRO-91 l ets you select and mo nitor the data channe l

frequency se nt w it h a 2-w ay rad io transmission, so you

can he ar the ca ll and res ponse for that u se r and more

easily “follow” the conversation.

The scanner also lets you scan conventional transmis-

sions, and is preprogrammed with service banks for

convenience. By pressing a single button, you can

quickly search those frequencies most commonly

used by public service and other agencies without te-

dious and complicat ed programming.

This sc an n er gives y o u d ir ec t ac c es s to ov er 30 ,00 0 e x-

citing frequencies, including police and fire depart-

ments, ambulance services, and amateur radio

services, and you can change your selection at any

time.

Your scanner also has th ese special features:

Triple-Conversion Circuitry

— virtually eliminates

any interference from IF (intermediate frequency) im-

ages, so you hear only the selected frequency.

Five Channel-Storage Banks — you can store up to

30 channels in each of 5 different banks to group chan-

nels so you can more easily identify calls.

Five Scan Lists — you can store up to 50 trunking IDs

in each trunk tracking bank.

Two-Second Scan Delay — delay s scanning for about

2 seconds before moving to another channel, so you

can hear mor e replies that are made on the same chan-

nel.

Lock-Out Functi on — lets you set your scanner to sk ip

over specified channels or frequencies when scanning

or searching, and skip over IDs when tracking trunked

systems.

Priority Channels — lets you program one channel in

each bank (5 in all) and then have the scanner check

that channel every 2 seconds while it scans the bank,

so you don’t miss transmissions on those channels.

Five Service Banks — frequencies are preset in sepa-

rate police (fire/emergency), aircraft, ham, marine, and

weather banks, to make it easy to locate specific types

of calls.

Hypersearch lets you set the scanner to search at

up to 300 steps per second. The normal search speed

is 100 steps per second.

Hyperscan— the scanner automatically scans up to

50 channels per second in frequency bands with 5 kHz

steps, to help you quickly find interesting broadcasts.

Key Lock — lets you lock the scanner‘s keys to help

prevent accidental changes to the scanner’s program-

ming.

Data Signal Skip — lets you set the scanner to skip

non-modulated or data signals (such as fax or modem

transmissions) during searches. This lets the scanner

avoid non-voice signals, making a search faster.

Manual Access — lets you directly access any channel.

Liquid-Crystal Display — makes it easy to view and

change programming information.

Display Backlight — makes the scanner easy to read

in low-light si tuations.

Flexible Antenna with BNC Connector — provides

excellent reception and is designed to help prevent an-

tenna breakage. Or, you can connect an external an-

tenna.

Moni tor Memori es let y o u tem p orarily st ore up t o 5

frequencies or IDs.

Memory Backup — keeps the frequencies stored in

memory for an extended time if the PRO-91 loses pow-

er.

Three Power Options — let you power the scanner

using internal batteries, external AC power using an

optional AC a dapter/charger, or DC power using an op-

tional DC cigarette-l ighter power cable.

Key Confirmation Tones — the scanner sounds a

tone when you perform an operation correctly, and an

error tone if you make an error.

Battery Save saves battery power when the scan-

ner does not detect any transmissions for more than 5

seconds when a channel is manually selected.

Battery Low Alertwarns you when battery power

gets low.

Your scanner can recei ve these bands:

Note:

Mobile use of this scanner is unlawful or requires

a permit in some areas. Check the laws in your area.

SCANNING LEGALLY

Your scanner covers frequencies used by many differ-

ent groups includin g police and fire depar tmen ts, ambu-

lance services, government agencies, private

companies, amateur radio services, military operations,

pager services, and wireline (telephone and telegraph)

service providers. It is legal to listen to almost every

transmission your scanner can receive. However, there

are some transmissions you should never intentionally

listen to. These include:

Telephone conversations (cellular, cordless, or

other private means of telephone signal transmis-

sion)

Pager transmissions

Any scrambled or encrypted transmissions

According to the Electronic Communications Privacy

Act (ECPA), you are subject to fines and possible im-

prisonment f or intentionally listen ing to, using, or divulg-

ing the contents of such a transmission unless you

have the consent of a party to the communication (un-

less such activ ity is otherwise ill egal).

This scanner is designed to prevent reception of illegal

transmissions, in compliance with the law which re-

quires that scanners be manufact ured in such a way as

to not be easily modifiable to pick up those transmis-

sions. Do not open your scanner’s case to make any

modifications that could allow it to pick up transmis-

sions that it is not legal to listen to. Doing so could sub-

ject you to legal penal ties.

We encourage respon sible, legal scanne r use.

PREPARATION

POWER SOURCES

You can power your scann er fr om any of thre e sou rces:

Internal batteries (not suppli ed)

Standard AC power (usin g an opti onal AC adapt er)

Vehicle battery power (using an optional DC

adapter)

Using Internal Batteries

You can power your scanner using four AA batteries.

For the longest operation and best performance, we

recommend alkaline batteries (such as Cat. No. 23-

552).

You can also use four rechargeable nickel-cadmium

batteries (Cat. No. 23-125). Before you use nickel-cad-

mium batteries, you must charge them (see “Charging

Nick el-Ca d mium Batt eries on P age 11).

Follow these steps to install batteries.

1. Turn

VOLUME /OFF

counterclockwise until it clicks

to make sure the power is turned off.

2. Slide up and hold the tab on the back of the scan-

ner, then pull up the battery compartment cover.

20-521 .fm Page 9 Wed ne sday, August 4, 199 9 3:32 PM

10

3. If you are installing alkaline batteries, use a

pointed object such as a pencil to set

ALKALINE

JACK NI-CD

inside the compartment to

ALKALINE

. Or,

if you are inst alling nickel-cadmium

batteries, s et i t to

NI-CD

.

Warning:

Never set

ALKALINE JACK NI-CD

to

NI-CD

if you are install ing non-rechar geable bat-

teries. Non-rechar geable batteries can get hot or

explode if you try to rec harge them.

4. Install two batteries in the compartment and two in

the cover as indicated by the polarity symbols (+

and –) marked inside those locations.

Cautions:

Use only fresh bat teries of the required size and

recommended type.

Always remove old or weak batteries. Batteries

can leak chemicals that destroy electronic cir-

cuits.

Do not mix old and new batteries, different

types of batteries (standard, alkaline, or

rechargeable), or rechargeable batteries of dif-

ferent capacit ies.

5. Replace the cover.

20-521 .fm Page 10 We dnesday, August 4, 1999 3:32 PM

11

If

BATT.Lo

flashes and the scanner beeps every 15

seconds, replace (standard/alkaline) or recharge (re-

chargeable nickel-cadmium) the batteries.

Caution: Always dispose of old batteries promptly and

properly. Do not bury or burn them.

Charging Nickel-Cadmium Batteries

The scanner has a built-in circuit that lets you recharge

nickel-cadmium batteries while they are in the scanner.

To charge the batteries, set

ALKALINE JACK NI-

CD

to

NI-CD

, install the nickel-cadmium batteries in the

scanner, and connect an external AC or DC adapter to

the scanner’s

POWER

jack (see “Using AC Power” on

Page 12 or “Using Vehicle Battery Power” on Page 13).

Warning: Do not connect either adapter to the scanner

if non-rechargeable batteries (such as alkaline batter-

ies) are ins tal led in the scan ner and

ALKALINE JACK

NI-CD

is set to

NI-CD

, or you are unsure of the

switch’s position. Non-rechargeable batteries will get

hot and can even explode if you try to recharge them.

Before you use nickel-cadmium batteries for the first

time, charge them at least 24 hour s to bring them to a

full charge.

Discharged batteries take about 10 to 18 hours to fully

recharge. If you use the scanner while the batteries are

charging, char ging takes longer.

Notes:

Nickel-cadmium batteries last longer and deliver

more power if you occasionally let them fully dis-

charge. To do this, simply use the scanner until it

beeps every 15 seco nds and

BATT.Lo

flashes.

To prevent damage to nickel-cadmium batteries,

never charge them in an area where the tempera-

ture is above 113°F or below 40°F.

20-521 .fm Page 11 We dnesday, August 4, 1999 3:32 PM

12

Important: At the end of a rechargeable battery’s use-

ful life, it must be recycled or disposed of properly.

Contact your local, county, or state hazardous waste

management authorities for information on recycling or

disposal programs in your area. Some options that

might be available are: municipal curb-side collection,

drop-off boxes at retailers such as your local Ra-

dioShack store, recycling collection centers, and mail-

back programs.

Using AC Power

You can power the scanner from a standard AC outlet

using an optional AC adapter (such as Cat. No. 273-

1665).

Warning: Do not use an AC adapter’s polarized plug

with an extension cord, receptacle, or other outlet un-

less the blades can be fully inserted to prevent blade

exposure.

Cautions:

The recommended AC adapter supplies 9 volts

and delivers at least 300 milliamps. It has a barrel

plug with a c enter negative tip that correctly fits the

scanner’s

POWER

jack. Using an adapter that

does not meet these specifications could dam age

the scanner or the adapter.

To protect your scanner and AC adapter, always

plug the adapter into the scanner before you plug

it into the AC outlet, and always unplug the

adapter from the AC outlet before you unplug it

from the scanner.

If batteries are installed, make sure the battery

switch inside the battery compartment is set to the

correct position (see “Using Internal Batteries” on

Page 9).

20-521 .fm Page 12 We dnesday, August 4, 1999 3:32 PM

1. Turn

VOLUME/OFF

counterclockwise until it clicks

to make sure the power is turned off.

2. Plug the adapter’s 3.4 mm outside diameter/1.3

mm inside diameter barrel plug into your scanner’s

POWER

jack.

3. Plug the other end of the adapter into a standard

AC outlet.

If rechargeable batteries are installed and

ALKALINE

JACK NI-CD

is set to

NI-CD

, the adapter powers the

scanner and recharges the batteries at the same time.

Using Vehicle Battery Power

You can power the scanner from your vehicle’s battery

power using an optional DC adapter such as Cat. No.

270-1560.

Cautions:

The recommended DC adapter supplies 9 volts

and delivers at least 300 milliamps. It has a barrel

plug with a center negati ve tip that correctly fits the

scanner’s

POWER

jack. Using an ad apter that does

not meet these specifications could damage the

scanner or t he adapter.

To protect your vehicle’s electrical system, always

plug the adapter into the scanner before you plug it

into your vehicle’s ci garette-lighter socket. Alwa ys

unplug the adapter from the vehicle’s cigarette-

lighter socket before you unplug it from the scan-

ner.

If batteries are installed, make sure the battery

switch inside the battery compartment is set to the

correct position (see “Using Internal Batteries” on

Page 9).

20-521 .fm Page 13 We dnesday, August 4, 1999 3:32 PM

14

1. Turn

VOLUME/OFF

counterclockwise until it clicks

to make sure the power is turned off.

2. Set the adapter’s voltage switch to 9V.

3. Connect the 3. 4 mm outer diameter/1.3 mm inner

diameter tip to the adapter cord, matching TIP to –.

4. Plug the adapter’s barrel plug into your scanner’s

POWER

jack.

5. Plug the other end of the adapter into your vehi-

cle’s cigarette-lighter socket.

If you have installed rechargeable batteries and

set

ALKALINE JACK NI-CD

to

NI-CD

, the

adapter powers the scanner and recharges the

batteries at the same time.

Note:

If the scanner does not operate properly when

you use a DC adap ter, unplug the adapter from the cig-

arette-lighter socket and clean the socket to remove

ashes and debris.

CONNECTING THE ANTENNA

Follow these st eps to attach the supplied flexible anten-

na to the connector on the top of your scanner.

1. Align the slots around the antenna’s c onnector with

the tabs on the scanner’s BNC connector.

2. Slide the antenna’s connector down over the scan-

ner’s connector and rotate the antenna connector’s

outer ring clockwise until it locks into place.

Connecting an Optional Antenna

The scanner’s BNC connector makes it easy to connect

a variety of optional antennas (such as an external mo-

bile antenna or outdoor base station antenna). Your lo-

cal RadioShack sto re sel ls a variety of antennas.

Note:

Always use 50-ohm coaxial cable, such as RG-

58 or RG-8, to connect an outdoor antenna. If the dis-

tance from the scanner to the antenna is over 50 feet,

use RG-8 low-loss dielectric coax ial cable. If your an-

tenna’s cable does not have a BNC connector, your lo-

cal RadioShack store carries a variety of BNC

adapters.

20-521 .fm Page 15 We dnesday, August 4, 1999 3:32 PM

16

CONNECTING AN EARPHONE/

HEADPHONES

For private listening, you can plug an earphone or

mono headphones (such as Cat. No. 33-178 or 20-

210) into the jack on top of your scanner. This auto-

matically disconnects the internal spea ker.

Listening Safely

To protect your hearing, follow these guidelines when

you use an earphone or headphones.

Do not listen at extremely high volume levels.

Extended high-volume listening can lead to per-

manent hearing loss .

Set the volume to the lowest setting before you

begin listening. After you begin listening, adjust

the volume to a comfortable level.

Once you set the volume, do not increase it. Over

time, your ears adapt to the volume level, so a vol-

ume level that does not cause discomfort might

still damage your hearing.

Traffic Safety

Do not use an earphone or headphones with your

scanner when operating a motor vehicle in or near traf-

fic. Doing so can create a traffi c hazard and could be il-

legal in some areas.

If you use an earphone or headphones with your scan-

ner, be very careful. Do not listen to a continuous

broadcast. Even though some earphones/headphones

let you hear some outside sounds when listening at

normal volume levels, they still can present a traffic

hazard.

20-521 .fm Page 16 We dnesday, August 4, 1999 3:32 PM

17

CONNECTING AN EXTENSION

SPEAKER

In a noisy area, an extension speaker (suc h as Cat. No.

21-549), positioned in the right place, might provide

more comfortable listening. Plug the speaker cable’s

1

/

8

-inch mini-plug into your scanner’s jack.

ATTACHING THE BELT CLIP

You can attach the supplied belt clip to make your

scanner easier to use when you are on the go. Use a

Phillips screwdriver and the supplied screws to attach

the belt clip to the scanner. Then sl ide the clip over your

belt or waistband.

ABOUT YOUR SCANNER

Once you under stand a few simple term s we use in this

manual and familiarize yourself with your scanner’s

features, you can put the scanner to work for you. You

simply determin e the ty pe of comm unications you want

to receive, then set the scanner to scan those commu-

nications.

A

frequency

is the tuning location of a station (ex-

pressed in kHz or MHz). To find active frequencies,

you use the

search

functio n.

Besides searching within a frequency range you deter-

mine, you can also search your scanner’s

service

banks

. Service banks are preset gr oups of frequencie s

categorized by type of service. For example, many am-

ateur radio frequencies ar e located in the

HAM2

service

bank.

When you find a frequency, you can store it into a pro-

grammable memory location called a

channel

. Chan-

nels are grouped into

channel-storage banks

. (This

scanner has 5 channel-storage banks of 30 channels

each). You can then

scan

the channel-storage banks

to see if there is activity on the frequencies stored

there.

Or, when you f ind a frequency, you can store it into a

temporary memory location called a monitor memory

until you decide whether or not to move it to a channel.

Just keep in mind — you

search

frequencies and

scan

channels.

You can also use your scanner to track trunked trans-

missions (see “Trunk Tracking” on Page 39).

UNDERSTANDING BANKS

Service Banks

The scanner is preprogrammed wi th all the fr equencies

allocated to the weather, ham, marine, air craft, and po-

lice (fire/emergency) services. This is handy for quickly

finding active frequencies instead of doing a limit

search (see “Servi ce Bank Search” on Page 28).

Channel Storage Banks

To make it easier to identify and select the channels

you want to listen to, channels are divided into 5 banks

of 30 channels each. Use each channel-storage bank

to group frequencies, such as those for the police de-

partment, fire department, ambulance services, or air-

craft (see “Guide to t he Acti on Bands” on Page 58).

For example, the police department might use four fre-

quencies, one for each side of town. You could pro-

gram the police frequencies starting with Channel 1

(the first channel in bank 1), and program the fire de-

partment frequencies starting with Channel 31 (the first

channel in bank 2).

FEATURES

Your RadioShack PRO-91 150-Channel Handheld
Trunking Scanner is one of a new generation of scan-
ners designed to track Motorola Type I and Type II
(such as Smartnet and Privacy Plus) and hybrid ana-
log trunking systems, which are extensively used in
many 800 MHz communication systems. 

Trunking communications systems let a large group of
2-way radio users (or even different groups of 2-way ra-
dio users) efficiently use a large range of frequencies.
Instead of selecting a specific frequency for a transmis-
sion, the user simply selects a talk group. The trunking
system automatically transmits the call on the first avail-
able frequency, and also sends (on a different frequen-
cy called a data channel) a code that uniquely identifies
that transmission.

Since the trunking system might send a call and its re-
sponse on different frequencies, it is difficult to listen to
trunked communications using a regular scanner. The
PRO-91 lets you select and monitor the data channel
frequency sent with a 2-way radio transmission, so you
can hear the call and response for that user and more
easily “follow” the conversation.

The scanner also lets you scan conventional transmis-
sions, and is preprogrammed with service banks for
convenience. By pressing a single button, you can
quickly search those frequencies most commonly
used by public service and other agencies without te-
dious and complicated programming.

This scanner gives you direct access to over 30,000 ex-
citing frequencies, including police and fire depart-
ments, ambulance services, and amateur radio
services, and you can change your selection at any
time. 

Your scanner also has these special features:

Triple-Conversion Circuitry — virtually eliminates
any interference from IF (intermediate frequency) im-
ages, so you hear only the selected frequency.

Five Channel-Storage Banks — you can store up to

30 channels in each of 5 different banks to group chan-

nels so you can more easily identify calls.

Five Scan Lists — you can store up to 50 trunking IDs

in each trunk tracking bank.

Two-Second Scan Delay — delay s scanning for about

2 seconds before moving to another channel, so you

can hear mor e replies that are made on the same chan-

nel.

Lock-Out Functi on — lets you set your scanner to sk ip

over specified channels or frequencies when scanning

or searching, and skip over IDs when tracking trunked

systems.

Priority Channels — lets you program one channel in

each bank (5 in all) and then have the scanner check

that channel every 2 seconds while it scans the bank,

so you don’t miss transmissions on those channels.

Five Service Banks — frequencies are preset in sepa-

rate police (fire/emergency), aircraft, ham, marine, and

weather banks, to make it easy to locate specific types

of calls.

Hypersearch lets you set the scanner to search at

up to 300 steps per second. The normal search speed

is 100 steps per second.

Hyperscan— the scanner automatically scans up to

50 channels per second in frequency bands with 5 kHz

steps, to help you quickly find interesting broadcasts.

Key Lock — lets you lock the scanner‘s keys to help

prevent accidental changes to the scanner’s program-

ming.

Data Signal Skip — lets you set the scanner to skip

non-modulated or data signals (such as fax or modem

transmissions) during searches. This lets the scanner

avoid non-voice signals, making a search faster.

Manual Access — lets you directly access any channel.

Liquid-Crystal Display — makes it easy to view and

change programming information.

Display Backlight — makes the scanner easy to read

in low-light si tuations.

PREPARATION

POWER SOURCES

You can power your scann er fr om any of thre e sou rces:

Internal batteries (not suppli ed)

Standard AC power (usin g an opti onal AC adapt er)

Vehicle battery power (using an optional DC

adapter)

Using Internal Batteries

You can power your scanner using four AA batteries.

For the longest operation and best performance, we

recommend alkaline batteries (such as Cat. No. 23-

552).

You can also use four rechargeable nickel-cadmium

batteries (Cat. No. 23-125). Before you use nickel-cad-

mium batteries, you must charge them (see “Charging

Nick el-Ca d mium Batt eries on P age 11).

Follow these steps to install batteries.

1. Turn

VOLUME /OFF

counterclockwise until it clicks

to make sure the power is turned off.

2. Slide up and hold the tab on the back of the scan-

ner, then pull up the battery compartment cover.

20-521 .fm Page 9 Wed ne sday, August 4, 199 9 3:32 PM

10

3. If you are installing alkaline batteries, use a

pointed object such as a pencil to set

ALKALINE

JACK NI-CD

inside the compartment to

ALKALINE

. Or,

if you are inst alling nickel-cadmium

batteries, s et i t to

NI-CD

.

Warning:

Never set

ALKALINE JACK NI-CD

to

NI-CD

if you are install ing non-rechar geable bat-

teries. Non-rechar geable batteries can get hot or

explode if you try to rec harge them.

4. Install two batteries in the compartment and two in

the cover as indicated by the polarity symbols (+

and –) marked inside those locations.

Cautions:

Use only fresh bat teries of the required size and

recommended type.

Always remove old or weak batteries. Batteries

can leak chemicals that destroy electronic cir-

cuits.

Do not mix old and new batteries, different

types of batteries (standard, alkaline, or

rechargeable), or rechargeable batteries of dif-

ferent capacit ies.

5. Replace the cover.

20-521 .fm Page 10 We dnesday, August 4, 1999 3:32 PM

11

If

BATT.Lo

flashes and the scanner beeps every 15

seconds, replace (standard/alkaline) or recharge (re-

chargeable nickel-cadmium) the batteries.

Caution: Always dispose of old batteries promptly and

properly. Do not bury or burn them.

Charging Nickel-Cadmium Batteries

The scanner has a built-in circuit that lets you recharge

nickel-cadmium batteries while they are in the scanner.

To charge the batteries, set

ALKALINE JACK NI-

CD

to

NI-CD

, install the nickel-cadmium batteries in the

scanner, and connect an external AC or DC adapter to

the scanner’s

POWER

jack (see “Using AC Power” on

Page 12 or “Using Vehicle Battery Power” on Page 13).

Warning: Do not connect either adapter to the scanner

if non-rechargeable batteries (such as alkaline batter-

ies) are ins tal led in the scan ner and

ALKALINE JACK

NI-CD

is set to

NI-CD

, or you are unsure of the

switch’s position. Non-rechargeable batteries will get

hot and can even explode if you try to recharge them.

Before you use nickel-cadmium batteries for the first

time, charge them at least 24 hour s to bring them to a

full charge.

Discharged batteries take about 10 to 18 hours to fully

recharge. If you use the scanner while the batteries are

charging, char ging takes longer.

Notes:

Nickel-cadmium batteries last longer and deliver

more power if you occasionally let them fully dis-

charge. To do this, simply use the scanner until it

beeps every 15 seco nds and

BATT.Lo

flashes.

To prevent damage to nickel-cadmium batteries,

never charge them in an area where the tempera-

ture is above 113°F or below 40°F.

20-521 .fm Page 11 We dnesday, August 4, 1999 3:32 PM

12

Important: At the end of a rechargeable battery’s use-

ful life, it must be recycled or disposed of properly.

Contact your local, county, or state hazardous waste

management authorities for information on recycling or

disposal programs in your area. Some options that

might be available are: municipal curb-side collection,

drop-off boxes at retailers such as your local Ra-

dioShack store, recycling collection centers, and mail-

back programs.

Using AC Power

You can power the scanner from a standard AC outlet

using an optional AC adapter (such as Cat. No. 273-

1665).

Warning: Do not use an AC adapter’s polarized plug

with an extension cord, receptacle, or other outlet un-

less the blades can be fully inserted to prevent blade

exposure.

Cautions:

The recommended AC adapter supplies 9 volts

and delivers at least 300 milliamps. It has a barrel

plug with a c enter negative tip that correctly fits the

scanner’s

POWER

jack. Using an adapter that

does not meet these specifications could dam age

the scanner or the adapter.

To protect your scanner and AC adapter, always

plug the adapter into the scanner before you plug

it into the AC outlet, and always unplug the

adapter from the AC outlet before you unplug it

from the scanner.

If batteries are installed, make sure the battery

switch inside the battery compartment is set to the

correct position (see “Using Internal Batteries” on

Page 9).

20-521 .fm Page 12 We dnesday, August 4, 1999 3:32 PM

1. Turn

VOLUME/OFF

counterclockwise until it clicks

to make sure the power is turned off.

2. Plug the adapter’s 3.4 mm outside diameter/1.3

mm inside diameter barrel plug into your scanner’s

POWER

jack.

3. Plug the other end of the adapter into a standard

AC outlet.

If rechargeable batteries are installed and

ALKALINE

JACK NI-CD

is set to

NI-CD

, the adapter powers the

scanner and recharges the batteries at the same time.

Using Vehicle Battery Power

You can power the scanner from your vehicle’s battery

power using an optional DC adapter such as Cat. No.

270-1560.

Cautions:

The recommended DC adapter supplies 9 volts

and delivers at least 300 milliamps. It has a barrel

plug with a center negati ve tip that correctly fits the

scanner’s

POWER

jack. Using an ad apter that does

not meet these specifications could damage the

scanner or t he adapter.

To protect your vehicle’s electrical system, always

plug the adapter into the scanner before you plug it

into your vehicle’s ci garette-lighter socket. Alwa ys

unplug the adapter from the vehicle’s cigarette-

lighter socket before you unplug it from the scan-

ner.

If batteries are installed, make sure the battery

switch inside the battery compartment is set to the

correct position (see “Using Internal Batteries” on

Page 9).

20-521 .fm Page 13 We dnesday, August 4, 1999 3:32 PM

14

1. Turn

VOLUME/OFF

counterclockwise until it clicks

to make sure the power is turned off.

2. Set the adapter’s voltage switch to 9V.

3. Connect the 3. 4 mm outer diameter/1.3 mm inner

diameter tip to the adapter cord, matching TIP to –.

4. Plug the adapter’s barrel plug into your scanner’s

POWER

jack.

5. Plug the other end of the adapter into your vehi-

cle’s cigarette-lighter socket.

If you have installed rechargeable batteries and

set

ALKALINE JACK NI-CD

to

NI-CD

, the

adapter powers the scanner and recharges the

batteries at the same time.

Note:

If the scanner does not operate properly when

you use a DC adap ter, unplug the adapter from the cig-

arette-lighter socket and clean the socket to remove

ashes and debris.

CONNECTING THE ANTENNA

Follow these st eps to attach the supplied flexible anten-

na to the connector on the top of your scanner.

1. Align the slots around the antenna’s c onnector with

the tabs on the scanner’s BNC connector.

2. Slide the antenna’s connector down over the scan-

ner’s connector and rotate the antenna connector’s

outer ring clockwise until it locks into place.

Connecting an Optional Antenna

The scanner’s BNC connector makes it easy to connect

a variety of optional antennas (such as an external mo-

bile antenna or outdoor base station antenna). Your lo-

cal RadioShack sto re sel ls a variety of antennas.

Note:

Always use 50-ohm coaxial cable, such as RG-

58 or RG-8, to connect an outdoor antenna. If the dis-

tance from the scanner to the antenna is over 50 feet,

use RG-8 low-loss dielectric coax ial cable. If your an-

tenna’s cable does not have a BNC connector, your lo-

cal RadioShack store carries a variety of BNC

adapters.

20-521 .fm Page 15 We dnesday, August 4, 1999 3:32 PM

16

CONNECTING AN EARPHONE/

HEADPHONES

For private listening, you can plug an earphone or

mono headphones (such as Cat. No. 33-178 or 20-

210) into the jack on top of your scanner. This auto-

matically disconnects the internal spea ker.

Listening Safely

To protect your hearing, follow these guidelines when

you use an earphone or headphones.

Do not listen at extremely high volume levels.

Extended high-volume listening can lead to per-

manent hearing loss .

Set the volume to the lowest setting before you

begin listening. After you begin listening, adjust

the volume to a comfortable level.

Once you set the volume, do not increase it. Over

time, your ears adapt to the volume level, so a vol-

ume level that does not cause discomfort might

still damage your hearing.

Traffic Safety

Do not use an earphone or headphones with your

scanner when operating a motor vehicle in or near traf-

fic. Doing so can create a traffi c hazard and could be il-

legal in some areas.

If you use an earphone or headphones with your scan-

ner, be very careful. Do not listen to a continuous

broadcast. Even though some earphones/headphones

let you hear some outside sounds when listening at

normal volume levels, they still can present a traffic

hazard.

20-521 .fm Page 16 We dnesday, August 4, 1999 3:32 PM

17

CONNECTING AN EXTENSION

SPEAKER

In a noisy area, an extension speaker (suc h as Cat. No.

21-549), positioned in the right place, might provide

more comfortable listening. Plug the speaker cable’s

1

/

8

-inch mini-plug into your scanner’s jack.

ATTACHING THE BELT CLIP

You can attach the supplied belt clip to make your

scanner easier to use when you are on the go. Use a

Phillips screwdriver and the supplied screws to attach

the belt clip to the scanner. Then sl ide the clip over your

belt or waistband.

ABOUT YOUR SCANNER

Once you under stand a few simple term s we use in this

manual and familiarize yourself with your scanner’s

features, you can put the scanner to work for you. You

simply determin e the ty pe of comm unications you want

to receive, then set the scanner to scan those commu-

pressed in kHz or MHz). To find active frequencies,

you use the

search

functio n.

Besides searching within a frequency range you deter-

mine, you can also search your scanner’s

service

banks

. Service banks are preset gr oups of frequencie s

categorized by type of service. For example, many am-

ateur radio frequencies ar e located in the

HAM2

service

bank.

When you find a frequency, you can store it into a pro-

grammable memory location called a

channel

. Chan-

nels are grouped into

channel-storage banks

. (This

scanner has 5 channel-storage banks of 30 channels

each). You can then

scan

the channel-storage banks

to see if there is activity on the frequencies stored

there.

Or, when you f ind a frequency, you can store it into a

temporary memory location called a monitor memory

until you decide whether or not to move it to a channel.

Just keep in mind — you

search

frequencies and

scan

channels.

You can also use your scanner to track trunked trans-

missions (see “Trunk Tracking” on Page 39).

this information should help you under stand each key’s

function.

HOLD

— holds the frequency search; holds on the cur-

rent ID in the trunk tracking mode.

SCAN

— scans through the st ored channels.

MAN (ma nual)

— stops scanning and lets you directly

enter a channel number or frequency.

PROG (program)

— stores frequencies into channels;

programs the trunking frequency, fleet map, and ID

memories.

TRUNK

switches between conventional and trunk

tracking.

LIMIT/SRC (search)

— starts a limit search; searches a

specified f requency range to find frequencies; searches

for another active ID while trunk tracking.

— turns on or off the data signal skip feature;

moves through menu settings while trunk tracking.

PRIORITY/H/S (Hypersearch)

sets and turns on and off

the priority fe ature

;

turns on and off Hypersearch.

L-OUT/S/S (search skip)

lets you lock out selected

channels or skip specified frequencies during a search;

lets you lock out a selected ID while trunk tracking.

KEYLOCK/

— locks the keypad to prevent acciden-

tal program changes; turns on the display light for 15

gram operation; changes the ID location number while

trunk tracking.

Number Keys each key has a single-digit label and a

range of numbers. The single digits are used to enter a

channel, frequency, service bank, or ID number. The

range of numbers (31–60, for example) are use d to en-

ter the channels that make up a memory bank.

MON/CLEAR/

— stores frequencies into monitor mem-

ories during a search; recalls frequencies from monitor

memories when programming a channel; stores

searched IDs into monitor memories or selects options

while trunk tracking; enters a decimal point or clears an

incorrect entry.

SVC (service)/E (enter )

— starts a service bank search;

enters frequencies into channels.

A LOOK AT THE DISPLAY

UNDERSTANDING BANKS

Service Banks

The scanner is preprogrammed wi th all the fr equencies

allocated to the weather, ham, marine, air craft, and po-

lice (fire/emergency) services. This is handy for quickly

finding active frequencies instead of doing a limit

search (see “Servi ce Bank Search” on Page 28).

Channel Storage Banks

To make it easier to identify and select the channels

you want to listen to, channels are divided into 5 banks

of 30 channels each. Use each channel-storage bank

to group frequencies, such as those for the police de-

partment, fire department, ambulance services, or air-

craft (see “Guide to t he Acti on Bands” on Page 58).

For example, the police department might use four fre-

quencies, one for each side of town. You could pro-

gram the police frequencies starting with Channel 1

(the first channel in bank 1), and program the fire de-

partment frequencies starting with Channel 31 (the first

channel in bank 2).
