SQUELCH
OPEN
The scan continues
until it is stopped man-
ually, and does not
pause even if it de-
tects signals.
This is not applicable
when the scan re-
sume is OFF and a
programmable step
(more than 1 kHz) is
selected.
Scan pauses on each
channel when the
scan resume is ON;
not applicable when
OFF.
SQUELCH
CLOSED
Scan stops when detecting a signal.
If you set scan resume ON in initial set mode,
the scan pauses for 10 sec. when detecting a
signal, then resumes. When a signal disap-
pears while scan is paused, scan resumes 2
sec. later.
