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:

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...

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.

computer bulletin boards, and contests for the radio enthusiast. See the enclosed printed
