FEATURES

Your RadioShack PRO-2045 200­Channel Weather Alert Home Scan­ner lets you in on all the action! This
scanner gives you direct access to
over 49,500 exciting f requen cies used
by police and fire departments, amb u­lance and transportation services, am­ateur radio, as well as aircraft
communications, Citizen’s Band, and
commercial FM and t elevision broad­casts.

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 se­lect 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 scan ner’s ability to
scan so many frequencies is its cus­tom-designed microprocessor — a
tiny, built-in computer.

more replies.

Data Skip — skips data signal s (non­modulated signals such as preamble
signals for pagers) during scan, limit
search, and direct search.

Attenuat or — 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 selec­tively listen to some business band
and amateur radio transmissions.

Backlit Display — lets you easily see
the indicators on the scanner’s dis­play, even at night.

We recommend you record your scan­ner’s serial number here. The number
is on the scanner’s back panel.

FCC NOTICE

Your scanner might caus e radio or T V
interference even when it is operat ing
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 electri­cal circuit from the receiver

• Contacting a RadioShack store for
help

SCANNING LEGALLY

Your scanner covers frequencies
used by many different groups includ­ing police and fire departments, ambu­lance services, government agencies,
private companies, amateur radio ser­vices, military operations, pager ser­vices, and wireline (telephone and
telegraph) service providers. It is lega l
to listen to almost every t ransmission
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 trans­mission)

• Pager transmissions

• Any scrambled or encrypted
transmissions

According to the Electronic Communi­cations Privacy Act (ECPA), you are
subject to fines and possible imprison­ment for intentionally listening to, us­ing, or divulging the contents of such a
transmission unless you have the con­sent of a party to the conversation (un­less such activity is otherwise illegal).
RadioShack encourages responsible,
legal scanner use.

If you cannot eliminate the interfer­ence, the FCC requires that you stop
using your scanner.

Optional Outdoor Antenna

The supplied anten na 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 anten­na (not supplied), such as a mobile,
telescoping, multi-band, or outdoor
base antenna.

The supplied telescoping antenna
helps your scanner receive st rong lo­cal signals. Follow these steps to in­stall the supplied antenna.

Warning: When installing or removing
an outdoor antenna, follow all cautions
and warnings included with the anten­na.

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

Note: Always use 50-ohm coaxial ca­ble to connect an outdoor ant enna to
your scanner. For lengths under 50
feet, use RG-58 or RG-8/M coaxial ca­ble. For lengths over 50 feet, use RG­8, low-loss coaxial cable. If the coaxial
cable’s connector does not fit the
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 out­door antenna and its location:

• The location of the external
antenna should be as high as pos­sible.

• The external antenna and
antenna cable should be as far
away as possible from sources of
electrical noise (appliances, other
radios, and so on).

ANT

RESETTING THE
SCANNER

If the scanner’s display locks up or
does not work properly after you con­nect 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
and 9, turn on the scanner.

• The external antenna should be
vertical.

Mount the antenna following the in­structions supplied with the antenna
and its mounting hardware, then route
the antenna cable t o the scanne r and
connect it to the
of the scanner.

TESTING ALERT
OPERATION

For your scanner’s weather alert func­tion to be effective, you must place the
scanner:

• Where it can receive an emer­gency alert broadcast (see “Test­ing 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 re­ception or that the t one 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
area, your scanner might be triggered
by a broadcast in one area , but no t be
triggered if you place it somewhere
else (even close by).

To test for actual reception, yo ur radio
must receive a test or emergency alert
broadcast. The National Weather Ser­vice (NWS) broadcasts a te st a lert ev­ery week on Wednesday between 11
AM and 12 Noon. To find out the spe­cific test schedule in your area, con­tact your local National Oceanic and
Atmospheric Administration (NOAA)
or National Weather Service office.

fringe

These offices are usually listed in the
telephone book under “US Govern­ment, 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 Sta nd­by Mode” o n Page 25) duri ng the time
when the test alert is broadcast in your
area.

If the test alert broadcast does not trig­ger your scanner’s tone, you are out of
range of the broadcast.

Note:

weather alert feature when you travel,
you cannot guarantee that an emer­gency alert broadcast will trigger the
scanner in all areas.

Notes for Weather Alerts:

If you use your scanner’s

• 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 lat­est weather information.

Testing the Weather Alert

Follow these steps to test the weather
alert — to hear how it sounds and e n­sure that the circuitry is working.

Note:

your scanner will sound an alert when
the weather service transmits an
emergency signal (see “Weather
Alert” on Page 25). Proper operation
is affected by the strength of the
weather service’s signal.
