About Scanning
Scanning Options
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.
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 the rate of about 15 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 scanning cycle resumes until another transmission is
received. You can set a 2 second delay (refer to 2 Second Delay, page .)
Types of Communication
You can monitor communications such as:
■Police and fire department (including rescue and paramedics)
■NOAA weather broadcasts (7 pre-programmed channels)
■Business/industrial radio
■Motion picture and press relay
■Utility
■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
You must program a frequency into each channel you want to use. If you do not

have any known local frequencies to program, call the 800 number on the
yellow sheet enclosed in this package. A Uniden representative should be able to
provide you with a few sample frequencies. Or, use the enclosed order form to
purchase a local frequency list.
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
prolonged periods without power causes clock reset.

Installing the BC244CLT
1. Insert small plug at the end of the AC Adapter cord into the AC 12V jack on 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 Telescoping Antenna into the ANT. jack. Extend the antenna to its full
height. For UHF frequencies, shortening the antenna may improve the reception.
4. Plug an optional external speaker (8-ohm) into the EXT. SP. jack.
If you are operating the scanner in the fringe area or need to improve reception, use
an optional antenna designed for multi-band coverage. (You can purchase this type
of antenna at a local electronics store.) If the optional antenna has no cable, use 50-
70 ohm coaxial cable for lead-in. A mating plug may be necessary for the optional
antennas.
If your scanner receives strong interference or electrical noise, relocate the scanner
or its antenna away from the source.

mode, the scanner samples the designated Priority
Channel every 2 seconds, regardless of any other

designated Priority Channel is detected, the scanner
monitors that channel until no signal is present.
Priority mode cancels when you turn off
your scanner.
11. MANUAL Key Use to stop scanning. Press MANUAL again to step to
the next channel. Also, use for direct channel access
by first entering the channel number and then

Scanning Overview
The BC244CLT has 30 memory channels; each can be programmed to store 1
frequency within the band of frequency coverage. (For a listing of frequency
ranges and bands, see Technical Specifications on page.)
When you press SCAN , the BC244CLT scans each programmed frequency for
activity (skipping channels that are locked out) at the rate of about 15 channels
per second. As the unit scans, the word SCAN moves across the LCD display.
When the scanning stops on an active frequency, it remains on that channel as
long as the transmission continues.
