INTRODUCTION
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.
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)
■
NOAA weather broadcasts (7 pre-programmed channels)
■
Business/industrial radio
■
Motion picture and press relay
■
Aircraft
■
Auto racing frequencies
■
Utilities
■
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
height. For UHF frequencies, shortening the antenna may improve the reception.
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.
