About Scanning

Scanning Options

Scanning is easy and fun with the BC278CLT 100-Channel Base Scanner with AM/FM Radio.

■Scan channels you have programmed

■Scan pre-programmed service and 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 BC278CLT scans programmed channels at rate of up to 25 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 (DELAY function).

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
