If the incoming signal disappears, scanning will
resume in about five seconds.

On the SSB/CW and SSB-based Data modes, the
scanner will pause on a received signal, then will
step across the signal very slowly, giving you
time to stop the scan, if you like. In these modes
on the VFO, the scanner does not stop, however.
5. To cancel scanning, press the
PTT
switch.

You may select the manner in which the scanner re-
sumes while it has paused on a signal, using Menu
item “

”. The default “
TIME
”
(5 sec) setting will cause the scanner to resume scan-
ning after five seconds; you may change it, however,
to resume only after the carrier has dropped out.
