UNDERSTANDING BANKS
Memory Banks
To make it easier to identify and select the channels you want to listen
to, the PRO-74’s channels are divided into 10 banks of 10 channels
each. Use each memory bank to group frequencies, such as the police
department, fire department, ambulance services, or aircraft (see
“Guide to the Action Bands” on Page 42). For example, the police de-
partment might use four frequencies, one for each side of town. You
could program the police frequencies starting with Channel 1 (the first
channel in bank 1) and program the fire department frequencies start-
ing with Channel 11 (the first channel in bank 2).
Service Banks
You can search for auto racing, marine, VHF, aircraft, military, amateur
radio, government, UHF, TV, and 800 MHz transmissions even if you
do not know the specific frequencies that are used in your area. And,
you can store any of the frequencies you find into channels.
This table shows each service bank’s name, what it is used for, and its
frequencies.
