Uniden BC45XLT manual Introduction, What is Scanning?, What is Chain Searching?

Introduction

The BC45XLT Scanner is a sophisticated information radio that allows you to monitor 10 different frequency bands and the NOAA weather information broadcasts. It is a state-of-the-art radio with scanning capabilities, and it can save up to 20 different frequencies in memory.

What is Scanning?

Unlike standard AM or FM radio stations, most two-way communications do not transmit continuously. The BC45XLT scans programmed channels until it finds an active frequency.

Scanning stops on an active frequency and remains on that channel as long as the transmission continues. When the transmission ends, the scanning cycle resumes until another transmission is received.

What is Chain Searching?

You can program five different personal search bands in your new scanner. You simply select a Chain Search location, define the search range, and begin your search.

The scanner looks for active communications in the range you’ve specified, so you can locate frequencies in your area which may not be listed in your Betty Bearcat Starter Frequency Guide.

You can set your scanner to search up to all five Chain Search bands at once, or you can turn off those search bands you do not want. This gives you complete control of the search function.
