A Look At The Keypad - Radio Shack PRO-528 Owner's Manual

A frequency, expressed in kHz or MHz, is the tuning location of a station. To find active frequencies, you use
the search function or refer to a frequency reference such as the included Trunking Frequency Guide.
Besides searching within a selected frequency range, you can also search your scanner's service banks.
Service banks are preset groups of frequencies categorized by the type of services that use those frequencies.
For example, many amateur radio frequencies are located in the
When you search and find a desired frequency, you can store it into a programmable memory location called a
channel. Channels are grouped into channel-storage banks. The scanner has 1000 channels in
channel-storage bank. Each bank is divided into ten 100-channel sets. You can scan the channel-storage
banks to see if there is activity on the frequencies stored there.
Just keep in mind — you search frequencies and scan channels.
