INTRODUCTION
About Scanning
Scanning Options
Scanning is easy and fun with the BC248CLT 50-Channel Base Scanner with AM/FM Radio.
You can scan in two 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 BC248CLT scans programmed channels at 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 departments (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
1
■
Many more in the 29-54MHz, 137-174MHz, and
406-512MHz ranges
■
AM/FM radio
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
prolonged periods without power causes the clock to reset.

Scanning Overview
The BC248CLT has 50 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 28.)
When you press SCAN, the BC248CLT 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 SCAN moves across the display, and the bank number flashes.
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. If you are in
the delay mode, 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.

4. To set the SQUELCH control to AU TO turn fully counterclockwise until control clicks into
place. Or, manually set squelch as follows:
■
Think of squelch as a gate. Turn SQUELCH fully counter clockwise. This raises the
“Squelch Gate” so high that only very strong signals can get through.
■
Turn SQUELCH fully clockwise until you hear a hiss. This lowers the “Squelch Gate”
so that everything gets through — noise, weak signals, and strong signals.
■
Turn SQUELCH back counter clockwise until the hiss stops. Now the “Squelch Gate”
allows only strong signals through.
10
5. The scanner automatically starts scanning.
But if you have not programmed any
channels yet, press WX to hear your local
weather broadcast.
6. Adjust VOLUME to a comfortable
listening level.
Programming Tips for Scanner
■
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 MANUAL to step up to the next channel.
Channels are grouped by banks for easy scanning control. The channels associated with
the banks are as follows:
■
Bank Number Channel Number
1 1 through 10
2 11 through 20
3 21 through 30
4 31 through 40
5 41 through 50
■
If you make an error during programming, or the frequency is out of range,
appears on the frequency display.
■
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 E again.
■
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.
■
Above 406MHz, the frequency steps are in 12.5kHz increments. To enter a frequency
such as 450.4875, press each of the seven digits in sequence.
Error
If
All Loc Out

Weather Channel
The BC248CLT allows you to search from 7 pre-programmed NOAA channels for your local
NOAA weather channel.
Press WX/ALERT to find the active weather
channel in your area. WX icon appears in the
display. It is possible that your area is covered by
more than one weather station.
All weather channels transmit continuous broadcasts. Once the
Weather Scan stops on a transmission, it remains on that channel.
Weather Scan does not resume automatically. You must press
WX/ALERT again to resume weather scanning.
When you press WX/ALERT, the BC244CLT immediately finds an active broadcast. If the
broadcast sounds weak and distant, press SCAN to look for a closer station.
In some parts of the country, you may not be able to monitor weather
broadcasts, such as in low-lying areas. Normally a higher location
improves the reception.
To exit Weather Channel Scan mode, press
SCANNER, RADIO AM/FM or OFF.
Do not program a weather frequency into one of the 50 channels.
Because weather channels transmit continuously, the scanner remains
on that channel, disrupting the scanning cycle. The Weather Scan
feature is provided specifically to avoid this occurrence.
21
Weather Alert
In Weather Alert Mode, your scanner functions as a severe weather warning radio. This is
especially useful when your area is expecting severe weather conditions late at night. When
you set the scanner to Weather Alert Mode, it emits a loud siren whenever your local NOAA
weather station broadcasts a severe weather emergency tone.
1. Press WX/ALERT to find the active
weather channel in your area. WX icon
appears in the display. It is possible that
your area is covered by more than one
weather station.

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
