Scanning the Stored Channels

Press 

SCAN/MAN 

until 

SCAN

 appears to continuously 

scan through all channels with stored frequencies.

displays that channel and frequency number, then 
it automatically begins scanning again when the 
transmission on that frequency ends.

the current channel for two seconds after the 
transmission ends.

even after the transmission stops, press

appears underneath them.

within the banks you have turned off.

one active bank.
