Scanning is easy and fun with the BC244CLT 30-Channel Base Scanner. You can
scan in 2 ways:
■
Scan channels you have programmed
■
Scan pre-programmed weather channels.
What is Scanning?
Unlike standard AM or FM radio stations, most 2-way communications do not
transmit continuously (see Types of Communication below).
The BC244CLT scans programmed channels at a rate of up to 12 channels per
second until it locates an active frequency. When the scanning stops on an active
frequency, it remains on that channel as long as the transmission continues.
When the transmission ends, the scanner stays on the channel for 2 more
seconds, waiting for a responding transmission. If no responding transmission is
detected, the scanning cycle resumes until another transmission is received.
Types of Communication
You can monitor communications such as:
■
Police and fire department (including rescue and paramedics)
Land transportation frequencies such as trucking firms, buses,
taxis, tow trucks, and railroads
■
Marine and amateur (ham radio) bands
■
And many more in the 29-54MHz, 137-174MHz, and
406-512MHz ranges
1
You must program a frequency into each channel you want to use. If you do not
have any known local frequencies to program, a Uniden representative should be
able to provide you with a few sample frequencies.
Where to Obtain More Information
The Bearcat Radio Club and other similar hobby clubs have publications,
information on computer bulletin boards, and contests for the radio enthusiast. See
the enclosed printed material for more information. Additional information is also
available through your local library.
Taking Proper Care of Your Scanner
■
Do not use the scanner in high-moisture environments such as the kitchen
or bathroom.
■
Avoid placing the unit in direct sunlight or near heating elements or vents.
■
Do not plug the scanner into an outlet controlled by a wall switch as
it could cause clock reset.

GETTING STARTED
Installing the BC244CLT
1. Insert the small plug at the end of the AC Adapter cord into the
the scanner.
2. Plug the AC Adapter into any standard 120VAC wall outlet. Do not plug into an
outlet controlled by a wall switch; it could cause clock reset.
3. Plug the Telescopic Antenna into the

4. Plug an optional external speaker (8-ohm) into the
If your scanner receives strong interference or electrical noise,
relocate the scanner or its antenna away from the source.
If you are operating the scanner in a fringe area or need to
improve reception, use an optional antenna designed for multiband coverage. (You can purchase this type of antenna at a
local electronics store.) If the optional antenna has no cable, use
a 50-70 ohm coaxial cable for lead-in. You may need a mating
plug for the optional antennas.

Programming Tips
■
Program one frequency per channel.
■
Channel 1 is the location of the default priority channel. Program the most
important frequency, or the one of major interest, into Channel 1. You may
also select any other channel to be the priority channel.
■
To quickly program a series of channels, start with the lowest number
channel. For example, when you are programming five new frequencies into
Channels 4 through 8, start with Channel 4. After you complete the
programming in one channel (by pressing E), press
the next channel.

■
If you program the same frequency in two channels, the display will indicate
the channel with the duplicate frequency. If you want to have two of the
same frequencies on different channels, accept the entry by pressing Eagain.

During numeric entry, if you know that you pressed the wrong number,
press .(decimal point) until the entry is cancelled out. When the previous
frequency is displayed, you may re-enter the frequency.

■
Turn the scanner off before disconnecting the power.
■
Always write down the programmed frequencies in the event of scanner
memory loss.
■
If scanner memory is lost, simply reprogram each channel. The display shows
AAllllLLooccOOuutt
■
Always press each keypad button firmly until you hear the entry tone for
that key.
Location
■
If your scanner receives strong interference or electrical noise, relocate the
scanner or its antenna away from the source of the noise. A higher elevation
may provide better reception. Also, try changing the length or the angle of
the antenna.
■
Avoid placing the unit in direct sunlight or near heating elements or vents.
■
Do not plug the scanner into an outlet controlled by a wall switch as it could
cause the clock to reset.
Cleaning
■
Disconnect the power to the unit before cleaning.
■
To prevent scratches, do not use abrasive cleaners or solvents. Be careful not
to rub the display window.
■
Do not use excessive amounts of water.
Repairs
■
Do not attempt any repair. The scanner contains no serviceable parts. Contact
the Uniden Customer Service Center or take it to a qualified repair
technician. (Page 25)
Birdies
■
Birdies are internally-generated signals inherent in the electronics of the
receiver. All radios are subject to receiving undesired signals or birdies. If your
scanner stops during Scan mode and no sound is heard, it may be receiving a
birdie. Press

■
If the programmed frequency is higher than
406MHz, a shorter antenna length may improve
the reception.
■
Relocate the scanner.
