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.

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 the rate of about 15 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 scanning cycle resumes until another transmission is
received. You can set a 2 second delay (refer to 2 Second Delay, page .)

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

Utility

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

You must program a frequency into each channel you want to use. If you do not
