About Scanning
Scanning is easy and fun with the UBC248CLT 50-Channel Base Scanner with AM/FM Radio.
What is Scanning?
Unlike standard AM or FM radio stations, most 2-way communications do not transmit
continuously (see Types of Communication below).
The UBC248CLT 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)
■
Business/industrial radio
■
Utilities
■
Land transportation frequencies such as trucking firms, buses,
taxis, tow trucks, and railroads
■
Marine and amateur (ham radio) bands
INTRODUCTION

You must program a frequency into each channel you want to use.
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 unplug the scanner for prolonged periods of time, lack of power will cause
the clock to reset.

Scanning Overview
The UBC248CLT 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 32.)
When you press SCAN, the UBC248CLT 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.
Searching Overview
In contrast to Scanning which monitors only a group of frequencies that are stored in the
scanner’s channels, Searching monitors all the frequencies within a pre-selected range of
frequencies (bound by upper and lower limits). If you find an interesting frequency while
searching, you can store it in a channel for easier access later.

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.

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.
If
All Loc Out
appears in the display, when you first turn the
scanner on, this indicates that all the channel information has been
manually erased. All channels are set to 0.0MHz. To clear this
message, program the frequency and channel information as desired.

Helpful Hints
General Use
■
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.
■
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 height or 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 prolonged periods
without power will 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.
Birdies
■
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. Birdies are
internally-generated signals inherent in the electronics of the receiver. Press SCAN to
resume scanning.
If you still cannot get satisfactory results and want additional information, or to return the
unit for service, please call the Uniden Customers Service Division.
