Scanner. This scanner gives you direct

access to over 25,000 frequencies, including

those used by police and fire departments,

ambulance services, government agencies,

air, and amateur radio services. You can

select up to 200 channels to scan, and you

can change your selection at any time.

Direct Search

— lets you search for new

and unlisted frequencies starting from a

specified frequency.

Priority Channel

— lets you program a

frequency in the priority channel to be

scanned every 2 seconds so you do not miss

important calls.

The secret to your scanner's ability to scan

so many frequencies is its built-in

microprocessor. Your scanner also has

these special features:

Weather Band (WX) Key

— scans seven

preprogrammed weather frequencies to keep

you informed about current weather

conditions.

Four Service Banks

— let you search

preset frequencies in separate fire/police, air,

ham radio, and marine banks, to make it

easy to locate specific types of calls.

Weather Alert

— automatically sounds the

alarm tone to advise of hazardous weather

conditions when the scanner detects an alert

signal on the local NOAA weather channel.

Two-Second Scan Delay

— delays

scanning for 2 seconds before moving to

another channel, so you can hear more

replies.

Lock-Out Function

— lets you set your

scanner to skip over specified channels or

frequencies when scanning or searching.

Ten Channel-Storage Banks

— let you

store up to 20 channels in each of 10

different banks, to group channels so you

can more easily identify calls.

Liquid Crystal Display

— makes it easy to

view and change programming information

at any time.

20 Monitor Memories

— let you temporarily

save up to 20 frequencies you locate during

a search, so you can move selected

frequencies to channel storage later.

12V power source (such as cigarette-lighter

socket) using a 12V, 300-mA DC cord and a

size M Adaptaplug™ connector (neither

supplied). Both are available at your local

RadioShack store.

Using AC Power

You can power the scanner using the

supplied 12V, 300mA AC adapter.

Cautions:

You must use a Class 2 power

source that supplies 12V DC

and delivers at least 300 mA.

• Mobile use of this scanner is unlawful or

requires a permit in some areas. Check

the laws in your area.

Connecting an Outdoor Antenna

Instead of the supplied antenna, you can

connect an outdoor base-station or mobile

antenna (neither supplied) to your scanner.

Your local RadioShack store sells a variety

of antennas. Choose the one that best meets

your needs.

CONNECTING AN ANTENNA

Connecting the Supplied Antenna

You must install an antenna before you can

operate the scanner.

When deciding on an outdoor antenna and

its location, consider these points:

The supplied telescoping antenna helps your

scanner receive strong local signals. To

install the antenna, thread it clockwise into

the hole on top of the scanner.

• The antenna should be located as high

as possible.

• The antenna and antenna cable should

be as far as possible from sources of

electrical noise (appliances, other

radios, and so on).

• The antenna should be vertical for the

best performance.

To connect an optional base-station or

mobile antenna, first remove the supplied

antenna from the scanner. Always use 50

Ohm coaxial cable, such as RG-58 or RG-8,

to connect the base-station or mobile

antenna. For lengths over 50 feet, use RG-8

low-loss dielectric coaxial cable. If the

antenna cable's connector does not fit in the

ANT

jack on the back of the scanner, you

Service Banks

The scanner is preprogrammed with the

frequencies allocated by fire/police, aircraft,

ham radio, and marine services. In these

service banks, you can search through the

frequencies and store them in channels for

fire/police, aircraft, ham radio, and marine

banks. This is handy for quickly finding active

frequencies instead of searching through an

entire band.

Note:

The frequencies in the scanner's

AVOIDING IMAGE FREQUENCIES

You might discover one of your regular stations on another frequency that is not listed. It might

be what is known as an image frequency. For example, you might find a service that regularly

uses a frequency of 453.275 also on 474.675.

To see if it is an image, do a little math.

Note the new frequency.

474.675

Double the intermediate frequency of 10.7 MHz (21.400)

and subtract it from the new frequency.

–21.400

453.275

If the answer is the regular frequency,

then you have tuned to an image.

Occasionally, you might get interference on a weak or distant channel from a strong broadcast

21.4 MHz above or below the tuned frequency. This is rare, and the image signal is usually

cleared whenever there is a broadcast on the actual frequency.

FREQUENCY CONVERSION

The tuning location of a station can be expressed in frequency (kHz or MHz) or in wavelength

(meters). The following information can help you make the necessary conversions.

1 MHz (million) = 1,000 kHz (thousand)

To convert MHz to kHz, multiply the number of MHz by 1,000:

30.62 MHz × 1000 = 30,620 kHz

To convert from kHz to MHz, divide the number of kHz by 1,000.

127,800 kHz ÷ 1000 = 127.8 MHz

To convert MHz to meters, divide 300 by the number of MHz.

300 ÷ 50 MHz = 6 meters

Scanner receives stations poorly or

not at all.

Check the antenna (indoor or outdoor).

Signals may be blocked from being received by the scanner due

to metal frames or material in the building. Change

the scanner’s location and try again.

The scanner’s keys do not work, or

The scanner might be locked. Reset the scanner. If that does

Scanner.”

Scanner does not work at all.

Check that the power supply (AC adapter/AC outlet) is working.

The scanner might be locked. Reset the scanner. If that does

not work, reinitialize the scanner. See “Resetting/Initializing the

Scanner.”

SQUELCH

is adjusted properly.

have an unclear transmission.

Be sure

Be sure birdie frequencies are not programmed, or listen to

birdie frequencies manually. See “Birdie Frequencies” on

Page 22.

2. Insert a pointed object, such as a

straightened paper clip, into the reset

opening on the back of the scanner (as

shown) and gently press then release

the reset button inside the opening. If

the scanner still does not work properly,

you might need to initialize the scanner.

If the scanner's display locks up or does not

work properly after you connect a power

source, you might need to reset or initialize

the scanner.

Important

: If you have problems, first try to

reset the scanner. If that does not work, you

can initialize the scanner; however, this

clears all information stored in your

scanner's memory.

Resetting the Scanner

1. Turn off the scanner, then turn it on

again.
