Program the high and low
frequency
edges
of
the
desired
scanning
range into MEMO
25 and
26.
See
p.
22
for programming
the memory
channels.
•
Either
channel can have the
higher
or lower
frequency
stored.
2)
Push the [VFO] switch
to
select VFO
mode.
3)
Select LSB, USB, CW, AM
or FM mode.
4)
Adjust the
[SQL]
control
to the
threshold
point.
5)
Push the [FUNC] switch
then
push the [VFO]
switch.
•
The scan
begins
from
the lower
limit of
the range.
•
The scan
stops
when
a
receive
signal
opens the squelch.
•
The scan resumes after
the
signal
disappears.
6)
Push the [VFO]
switch again
to stop
the scan.

The following
switches and
controls
also stop the
scan:

SUPPLEMENTAL
SCAN
SETTINGS
(1)
SCAN SPEED
Scan speed in the
IC-725
is set
for
fast speed
at
the factory.
See
p.
28
for converting
to a
slower
scan speed.
(2)
SCAN CLEAR
The
scan function can
be automatically cleared when the
transceiver
receives
a
signal.
See
p.
28
for
setting the
transceiver
in
the scan clear
condition.
