FEATURES

Your RadioShack PRO-2045 200-

Channel Weather Alert Home Scan-

ner lets you in on all the action! This

scanner gives you direct access to

over 49,500 exciting frequencies used

by police and fire departments, ambu-

lance and transportation services, am-

ateur radio, as well as aircraft

communications, Citizen’s Band, and

commercial FM and television broad-

casts.

You can select up to 200 channels for

your scanner to scan, and you can

change your selections at any time. Its

rotary tuning control lets you easily se-

lect frequencies and channels. Plus,

when you turn on the weather alert

function, the scanner sounds an alarm

if the weather service transmits a

weather alert tone.

The secret to your scanner’s ability to

scan so many frequencies is its cus-

tom-designed microprocessor — a

tiny, built-in computer.

Your scanner has these features:

WX Alert — warns you of serious

weather conditions by sounding an

alarm if the weather service transmits

a weather alert tone.

Weather Band Auto Scan — scans

the preprogrammed weather frequen-

cies so you can stay informed about

current weather conditions.

perscan — scans programmed

channels at up to 50 channels per

second.

persearch — lets you set the scan-

ner to search at up to 300 steps per

second.

Rotar

Tuner — lets you easily tune

and select frequencies or channels.

Auto Sort — lets you scan the chan-

nels stored in a bank, in order from

lowest to highest frequency, to in-

crease scanning speed.

Auto Store — quickly finds and auto-

matically stores active frequencies

into the selected banks (but does not

store the frequency if it is already

stored in another channel).

Ten Channel-Stora

e Banks — let

you store 20 channels in each of 10

banks to group frequencies so you

can easily identify calls.

Frequenc

Transfer — lets you easi-

ly organize your frequencies by trans-

ferring them from one channel to

another.

Monitor Memories — let you store up

to 10 frequencies you locate during a

frequency search.

Limit Search — lets you search for

transmissions within a set range.

20-418.fm Page 2 Wednesday, August 4, 1999 12:42 PM

Direct Search — lets you search for

transmissions starting from a frequen-

cy you specify.

Count Feature — lets you keep track

of how many times your scanner has

stopped on a channel.

Search Skip — lets you select up to

50 frequencies for the scanner to skip

during a search, so you can avoid fre-

quencies you have already discovered

or that have a continuous transmis-

sion.

Two-Second Scan Delay — delays

scanning for 2 seconds before moving

to another channel, so you can hear

more replies.

Data Skip — skips data signals (non-

modulated signals such as preamble

signals for pagers) during scan, limit

search, and direct search.

Lock-Out Function — prevents

channels you select from being

scanned.

Priority Channels — checks 10 spec-

ified channels every 2 seconds so you

do not miss important calls.

Automatic Modulation Mode — se-

lects the modulation method — nar-

row-band frequency modulation

(NFM) or amplitude modulation (AM)

— most often used for each band, and

lets you manually override the preset

mode.

Attenuator — reduces the scanner’s

sensitivity to help limit reception to

strong, nearby transmitters.

Memory Backup — keeps stored

channel frequencies in memory for up

to 3 days during a power loss.

CTCSS Option — with an optional

CTCSS tone circuit board, you can

use the Continuous Tone Coded

Squelch System (CTCSS) to selec-

tively listen to some business band

and amateur radio transmissions.

Backlit Display — lets you easily see

the indicators on the scanner’s dis-

play, even at night.

We recommend you record your scan-

ner’s serial number here. The number

is on the scanner’s back panel.

Serial Number: _________________

Your scanner has the following pre-

programmed weather channels:

• 162.4000 MHz (NFM)

• 162.4250 MHz (NFM)

• 162.4500 MHz (NFM)

• 162.4750 MHz (NFM)

• 162.5000 MHz (NFM)

• 162.5250 MHz (NFM)

• 162.5500 MHz (NFM)

20-418.fm Page 3 Wednesday, August 4, 1999 12:42 PM

Your scanner can receive all of these

bands:

FCC NOTICE

Your scanner might cause radio or TV

interference even when it is operating

properly. To determine if your scanner

is causing the interference, turn off

your scanner. If the interference goes

away, your scanner was causing it.

Try to eliminate the interference by:

• Moving your scanner away from

the receiver

• Connecting your scanner to an

outlet that is on a different electri-

cal circuit from the receiver

• Contacting a RadioShack store for

help

If you cannot eliminate the interfer-

ence, the FCC requires that you stop

using your scanner.

SCANNING LEGALLY

Your scanner covers frequencies

used by many different groups includ-

ing police and fire departments, ambu-

lance services, government agencies,

private companies, amateur radio ser-

vices, military operations, pager ser-

vices, 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 (either

cellular, cordless, or other private

means of telephone signal trans-

mission)

• Pager transmissions

• Any scrambled or encrypted

transmissions

According to the Electronic Communi-

cations Privacy Act (ECPA), you are

subject to fines and possible imprison-

ment for intentionally listening to, us-

ing, or divulging the contents of such a

transmission unless you have the con-

sent of a party to the conversation (un-

less such activity is otherwise illegal).

RadioShack encourages responsible,

legal scanner use.

PREPARATION

CONNECTING POWER

You can power your scanner from a

standard AC outlet using the supplied

AC adapter or from your vehicle’s bat-

tery using an optional DC power cord.

If a power failure occurs or if the pow-

er cord is disconnected, the scanner’s

memory backup circuit keeps informa-

tion in memory for up to 3 days.

Note: The memory backup circuit be-

gins to protect memory within a few

minutes after you plug in the scanner.

Using Standard AC Power

Warnin

: Do not use the AC adapter

with an extension cord unless the

blades can be fully inserted.

Cautions:

• The supplied AC adapter supplies

12 volts and delivers 500 milli-

amps. Its center tip is set to posi-

tive, and its plug properly fits the

scanner’s DC 12V jack. Using an

AC adapter that does not meet

these specifications could dam-

age the scanner or the adapter.

• Connect the adapter to the scan-

ner before you connect it to an AC

outlet. Disconnect the adapter

from the AC outlet before you dis-

connect it from the scanner.

• If you have difficulty inserting the

AC adapter’s plug, do not force it.

Turn it over and reinsert it.

Follow these steps to use AC power.

1. Insert the supplied AC adapter’s

barrel plug into the scanner’s DC

12V jack.

2. Plug the adapter’s power module

into a standard AC outlet.

Using Vehicle Battery Power

Use a DC power cord (not supplied),

such as RadioShack Cat. No. 270-

1533, to power your scanner in your

vehicle.

Cautions:

• The DC power cord you select

must supply 12 volts and deliver

at least 500 mA. Its center tip

must be positive, and its plug

must fit the scanner’s DC 12V jack.

The recommended power cord

meets these specifications. Using

a power cord that does not meet

these specifications could dam-

age the scanner or power cord.

• Connect the power cord to the

scanner before you plug it into

your vehicle. Disconnect the

power cord from the vehicle

before you disconnect it from the

scanner.

DC 12V

20-418.fm Page 7 Wednesday, August 4, 1999 12:42 PM

• If you use your scanner in your

vehicle with the engine running,

you might hear electrical noise

from the scanner. This is normal.

Note: Mobile use of this scanner is

unlawful or requires a permit in some

areas. Check the laws in your area.

Follow these steps to use vehicle bat-

tery power.

1. Insert the DC power cord’s barrel

plug into the scanner’s DC 12V

jack.

2. Plug the DC power cord’s ciga-

rette-lighter plug into your vehi-

cle’s cigarette-lighter socket.

CONNECTING AN

ANTENNA

You can connect either the supplied

telescoping antenna or an optional an-

tenna to your scanner.

Telescoping Antenna

The supplied telescoping antenna

helps your scanner receive strong lo-

cal signals. Follow these steps to in-

stall the supplied antenna.

1. Hold the antenna so it stands

straight up.

2. Gently push the antenna’s plug

onto the ANT jack on the scan-

ner’s back panel.

The antenna’s length affects recep-

tion. Adjust the antenna’s length as

follows for the best results.

Optional Outdoor Antenna

The supplied antenna is usually good

for strong, local signals. However, for

the best results in receiving weaker,

more distant signals on all bands, you

can attach an optional outdoor anten-

na (not supplied), such as a mobile,

telescoping, multi-band, or outdoor

base antenna.

Warning: When installing or removing

an outdoor antenna, follow all cautions

and warnings included with the anten-

na.

DC 12V

29–150 MHz Extend fully

150–174 MHz Extend only 3 seg-

ments

216–406 MHz Extend only 2 seg-

ments

406–1000 MHz Collapse Fully (only

1 segment extended)

ANT

20-418.fm Page 8 Wednesday, August 4, 1999 12:42 PM

Note: Always use 50-ohm coaxial ca-

ble to connect an outdoor antenna to

your scanner. For lengths under 50

feet, use RG-58 or RG-8/M coaxial ca-

ble. For lengths over 50 feet, use RG-

8, low-loss coaxial cable. If the coaxial

cable’s connector does not fit the ANT

jack, you might also need an adapter.

Your local RadioShack store sells a

complete line of outdoor antennas,

adapters, BNC connectors, and

mounting hardware.

For the best performance, consider

the following when deciding on an out-

door antenna and its location:

• The location of the external

antenna should be as high as pos-

sible.

• The external antenna and

antenna cable should be as far

away as possible from sources of

electrical noise (appliances, other

radios, and so on).

• The external antenna should be

vertical.

Mount the antenna following the in-

structions supplied with the antenna

and its mounting hardware, then route

the antenna cable to the scanner and

connect it to the ANT jack on the back

of the scanner.

RESETTING THE

SCANNER

If the scanner’s display locks up or

does not work properly after you con-

nect power or after a power surge, you

might need to reset the scanner.

Caution: This procedure clears all the

information you have programmed

into the scanner. Use this procedure

only when you are sure your scanner

is not working properly.

1. Turn off the scanner.

2. While you press and hold down 2

and 9, turn on the scanner.

USING THE FEET

To tilt the display for the best viewing

angle and to provide the best traction,

pull down on the scanner’s feet so

they lock into place.

ANT

20-418.fm Page 9 Wednesday, August 4, 1999 12:42 PM

TESTING ALERT

OPERATION

For your scanner’s weather alert func-

tion to be effective, you must place the

scanner:

• Where it can receive an emer-

gency alert broadcast (see “Test-

ing Alert Reception” on this page)

• Where you can hear its alert tone

(See “Testing the Weather Alert”

on Page 11).

Once you determine a location that

meets these two conditions, leave the

scanner there for the best protection.

Testing Alert Reception

The fact that you get clear voice re-

ception or that the tone sounds when

you test the weather alert does not

guarantee that an emergency alert

broadcast will trigger your scanner’s

alert tone. Also, if you are in a

fringe

area, your scanner might be triggered

by a broadcast in one area, but not be

triggered if you place it somewhere

else (even close by).

To test for actual reception, your radio

must receive a test or emergency alert

broadcast. The National Weather Ser-

vice (NWS) broadcasts a test alert ev-

ery week on Wednesday between 11

AM and 12 Noon. To find out the spe-

cific test schedule in your area, con-

tact your local National Oceanic and

Atmospheric Administration (NOAA)

or National Weather Service office.

These offices are usually listed in the

telephone book under “US Govern-

ment, Department of Commerce.”

To verify that your scanner receives

the test alert properly, set the scanner

to the weather alert standby mode

(see “Using the Weather Alert Stand-

by Mode” on Page 25) during the time

when the test alert is broadcast in your

area.

If the test alert broadcast does not trig-

ger your scanner’s tone, you are out of

range of the broadcast.

Note: If you use your scanner’s

weather alert feature when you travel,

you cannot guarantee that an emer-

gency alert broadcast will trigger the

scanner in all areas.

Notes for Weather Alerts:

• To ensure your scanner will sound

the alert tone when it receives an

emergency signal, keep the

antenna fully extended at all

times.

• If severe weather threatens, do

not wait for an alert tone; turn on

your scanner and monitor the lat-

est weather information.
