your scanner is causing it. Try to eliminate the interference by:
Moving your scanner away from the TV or radio
Connecting your scanner to an outlet that is on a different electrical
circuit from the TV or radio
Contacting your local Radio Shack store for help
This device complies with Part 15 of the FCC Rules. Operation is subject
to the following two conditions: (1) This device may not cause harmful
interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
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
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 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 content of a party to the communication (unless such activity
is otherwise illegal). We encourage responsible, legal scanner use.
This scanner is primarily designed for use in the home as a base station.
You can place it on a desk, shelf, or table.
Your scanner's front feet fold up or down. Adjust them to give you the
best view of the display.
POWER SOURCES
You can power your scanner from either of these sources:
Standard AC power
Vehicle battery power using an optional DC cigarette-lighter power
cord
NOTE: If the scanner stops working properly after connecting it to power,
try resetting it.
The memory backup circuit begins to function a few minutes after
you supply power to the scanner. How long the scanner will
maintain channels stored in memory depends on how long power has
been supplied to the scanner. If power is continuously supplied
to the scanner for at least 4 days, the memory backup circuit
maintains the channels stored in memory for up to 3 months.
Using Standard AC Power
Plug the scanner's power cord into a standard AC outlet.
WARNING: Do not use the scanner's polarized plug with an extension cord,
receptacle, or other outlet unless the blades can be fully
inserted to prevent blades can be fully inserted to prevent
blade exposure.
Using Vehicle Battery Power
If your AC power does not work in an emergency, you can power your scanner
from your vehicle's cigarette-lighter socket with an optional DC
cigarette-lighter power cord such as Cat. No. 270-1533 (not supplied).
To connect an optional DC cigarette-lighter power cord, insert its barrel
plug into the DC 13.8V jack on the back of the scanner, then plug the
power cord into your vehicle's cigarette-lighter socket.
Cautions:
If you use a DC cigarette-lighter power cord with the scanner, it must
supply at least 1 amp of vehicle power. Its center tip must be set to
positive, and its plug must correctly fit the DC 13.8 V jack on the
back of the scanner. The recommended power cord meets these
specifications. Using a power cord that does not meet these
specifications could damage the scanner or the power cord.
To protect your vehicle's electrical system, always plug the power cord
into the scanner before you plug it into your vehicle's cigarette-lighter
socket. Always unplug the power cord from the vehicle's
cigarette-lighter socket before you unplug it from the scanner.
Notes:
Mobile use of this scanner is unlawful or requires a permit in some
areas. Check the laws in your area.
If the scanner does not operate properly when you connect a DC power
cord, unplug the power cord from the cigarette-lighter socket and clean
the socket to remove ashes and other debris.
CONNECTING THE ANTENNA
The supplied telescoping antenna helps your scanner receive strong local
signals. To install the antenna, screw it clockwise into the hole on the
scanner's top.
The scanner's sensitivity depends on the antenna's length and various
environmental conditions. For the best reception of the transmissions you
want to hear, adjust the antenna's length.
Frequency Antenna Length
29-174 MHz Extend Fully
380-512 MHz Extend 2 segments
806-960 MHz Collapse fully (1 segment only)
Connecting an Optional Antenna
The ANT jack on the back of the scanner makes it easy to use the scanner
with a variety of antennas. Instead of the supplied antenna, you can
attach a different one, such as an external mobile antenna or outdoor base
station antenna. Your local RadioShack store sells a variety of antennas.
When deciding on an antenna and its location, consider the following:
The location of the antenna should be 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.
Always use 50-ohm coaxial cable, such as RG-58 or RG-8, to connect an
outdoor antenna. For lengths over 50 feet, use RG-8 low-loss dielectric
coaxial cable. If the coaxial cable's connector does not fit in the ANT
jack, you might also need a PL-259-to-BNC antenna plug adapter, such as
Cat. No. 278-120. Your local RadioShack store carries a wide variety of
coaxial antenna cable and connectors.
Follow the installation instructions supplied with the antenna, route the
antenna cable to the scanner, then connect it to the ANT BNC-type jack on
the back of the scanner.
Warning: Use extreme caution when installing or removing an outdoor
antenna. If the antenna starts to fall, let it go. It could
contact overhead power lines. If the antenna touches a power
line, contact with the antenna, mast, cable, or guy wires can
cause electrocution and death. Call the power company to remove
the antenna. Do not attempt to do so yourself.
Caution: Do not run the cable over sharp edges or moving objects.
CONNECTING AN EARPHONE/HEADPHONES
For private listening, you can plug an earphone or mono headphones (such
as Cat. No. 33-175 or 20-210) into the headphones jack on the front of
your scanner. This automatically disconnects the internal speaker.
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 permanent 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 volume level that does not cause discomfort
might still damage your hearing.
Traffic Safety
Do mot use an earphone of headphones with your scanner when operating a
motor vehicle in or near traffic. Doing so can create a traffic hazard
and could be illegal in some areas.
If you use an earphone or headphones with your scanner while operating
a motor vehicle, 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.
CONNECTING AN EXTENSION SPEAKER
In a noisy area, an extension speaker (Cat. No. 21-549) or an amplified
speaker (Cat. No. 21-541) might provide more comfortable listening.
Plug the speaker cable's 1/8-inch mini-plug into the EXT SPKR jack on the
back of your scanner.
UNDERSTANDING YOUR SCANNER
Once you understand a few simple terms we use in this manual and
familiarize yourself with your scanner's features, you can put the
scanner to work for you. You simply determine the communications you
want to receive, then set the scanner to scan those frequencies.
A frequency is the turning location of a station (expressed in kHz or
MHz). To find active frequencies, you can use the search function to
search bands, which are preset ranges of frequencies.
When you find a frequency, you can store it into a permanent memory
location called a channel, which is grouped with your other channels
in a channel-storage bank. You can then scan the channel-storage banks
to see if there is activity on the frequencies stored there. Each time
the scanner finds an active frequency, it stays on that channel until the
transmission ends.
Another option is to store the frequency into a temporary memory location
called a monitor memory until you decide to move it to a channel.
Just keep in mind - you search frequencies and scan channels.
A LOOK AT THE KEYPAD
Your scanner's keys might seem confusing at first, but this information
should help you understand each key's function.
BAND - selects a preprogrammed search band.
SCAN - scans through the programmed channels.
MANUAL - stops scanning to let you directly enter a channel number.

UNDERSTANDING BANDS/BANKS/MEMORIES
Search Bands
Your scanner can tune over 32,000 different frequencies. Many of these
frequencies are grouped within permanent memory locations called
search bands (1-17).
Band Search Description
Range
(MHz)
01 29-30 10-Meter Amateur Radio
02 30-50 VHF Lo
03 50-54 6-Meter Amateur Radio
04 108-136 Aircraft
05 144-148 2-Meter Amateur Radio
06 148-174 VHF Hi
07 380-384 Military Aircraft
08 406-420 Government
09 420-450 70-Centimeter Amateur Radio
10 450-470 UHF Lo
11 851-856 UHF Hi
12 856-866 UHF Hi
13 866-869 UHF Hi
14 935-940 UHF Hi
15 940-941 UHF Hi
16 941-952 UHF Hi
17 952-960 33-Centimeter Amateur Radio
You can search these bands to quickly find active frequencies you
might want to store into the scanner's channels. For example, if you
wanted to search for transmissions between pilots and the control tower at
an air show, you could search only the search bands where you are most
likely to hear the transmissions (4 and 7).
NOTES: The scanner can search for transmissions on frequencies that are
not stored in any of the search bands.
The actual search range of Band 04 is 108-136.975 MHz.
The frequencies in the scanner's search bands are preset. You
cannot change them.
"General Guide to Scanning," Faxback Doc. # 38900 lists other
frequency ranges and the broadcasts you are likely to hear on those
frequencies.
Channel-Storage Banks
To make it easier to identify and select the channels you want to listen
to, channels are divided into 10 channel-storage banks (1-10) of 40
channels each. You can use each channel-storage bank to group
frequencies, such as those used by the police department, fire department,
ambulance services, and aircraft.
For example, there might be three or four police departments in your
area, using several different frequencies. Additionally, there might
be other law enforcement agencies such as state police, county sheriffs,
or SWAT teams that use their own frequencies. You could program all
law enforcement frequencies starting with Channel 1 (the first channel
in Bank 1), then program the fire department, paramedic, and other public
safety frequencies starting with Channel 41 (the first channel in Bank 2).
Monitor Memories
The scanner also has 40 monitor memories that you can use to temporarily
store frequencies while you decide whether to save them into channels.
This is handy for quickly storing an active frequency when you are
searching through an entire band.
You can only store a frequency into a monitor memory during a band, limit,
or direct search. See "Operation," Faxback Doc. # 38898.
You can select monitor memories manually, but you cannot scan them.
