versatility at
the touch
of
a
few
switches.

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,

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.

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.
