About Scanning
Scanning Options
Scanning is easy and fun with the BC244CLT 30-Channel Base Scanner. You can
scan in 2 ways:
nScan channels you have programmednScan 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:
nPolice and fire department (including rescue and paramedics)nNOAA weather broadcasts (7 pre-programmed channels)nBusiness/industrial radio nMotion picture and press relay nAircraftnAuto racing frequenciesnUtilitiesnLand transportation frequencies such as trucking firms, buses,
taxis, tow trucks, and railroads
nMarine and amateur (ham radio) bandsnAnd 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, 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
nDo not use the scanner in high-moisture environments such as the kitchen
or bathroom.
nAvoid placing the unit in direct sunlight or near heating elements or vents.nDo not plug the scanner into an outlet controlled by a wall switch as 
it could cause clock reset.
Unpacking

Installing the BC244CLT 
1. Insert the small plug at the end of the AC Adapter cord into the AC 10Vjack 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 Telescopic 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 a 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
a 50-70 ohm coaxial cable for lead-in. You may need a mating
plug for the optional antennas.
If your scanner receives strong interference or electrical noise,
relocate the scanner or its antenna away from the source.

. LOCKOUT KeyPrevents scanning of the displayed channel. The L/O
indicator appears when the current channel is locked out. 
Lockout is retained in memory. Press 
LOCKOUT again to unlock 
the channel. Lockout is active only when the scanner stops on an 
active channel or a channel selected in Manual Mode.

Scanning Overview
The BC244CLT has 30 memory channels. Each can be programmed to store one
frequency within the band of frequency coverage. (For a listing of frequency ranges
and bands, see Technical Specifications on page 26.)
When you press 
SCAN, the BC244CLT scans each programmed frequency for
activity (skipping channels that are locked out) at the rate of about 12 channels per
second. As the unit scans, the word S SC
CA
AN
N
moves across the display.
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 two more seconds, waiting for a responding transmission. If no
responding transmission is detected, the scanning cycle resumes.
