DMemory select scan

Memory select scan allows you to increase scan effi- ciency by searching for specified channels only, thereby increasing the rate at which the scan cycles through the memory channels. Set high priority chan- nels as ‘select’ channels (memory select scan searches for signals on these channels) while leaving out lower priority channels.

Preparation—specifying select channels:

Select the channel you want to specify as a ‘select’ channel, then push [SEL] for 1 sec.

Start/stop:

Select the desired bank using [M-CH• BANK] or [ENT • BANK].

Set the squelch control to the threshold point.

Push [SEL] momentarily to start scan.

SEL” appears in the bank name area.

Push [SEL] again to stop the scan.

NOTE: Memory select scan does not start unless 2 or more channels in the bank are specified as select channels.

Convenient:

The same convenient functions are available as de- scribed above.
