6. The receive mode fun-
ctions properly and
your signals are trans-
mitted, but you are
unable to make con-
tact with another
station.
Possible Cause
The SIMPLEX/DUPLEX Swi-
tch is in "DUP" position.
(When desiring SIMPLEX
mode.)
~The SIMPLEX/DUPLEX Swi-
tch is in "SIMP" position.
(When desiring DUPLEX
mode.)
Improper frequency split or
input/output frequency of
the repeater.
The main switch of the power
source was turned OFF or the
power plug was unplugged.
. The memorized fre-
quencies are lost and
the display shows 5.00
(IC-25A : 6.01) when
power switch is turned
ON.
The power failed (when using
the AC power source).
No frequency is programmed
in the memory channels or
the same frequency is pro-
grammed in all the memory
channels.
The VFO/MEMORY CHAN-
NEL Switch is not in a
Memory Channel position.
. Те memory scan
operation does not
function when the S/S
Switch is pushed.
The same frequency is pro
grammed in the memory
channel 1 and 2, or the
programmed frequency in the
memory channel 1 is higher
than the one in the channel 2.
The VFO/MEMORY CHAN-
NEL Switch is not in the
VFO position.
. The programmed scan
operation does not
function when the S/S
Switch is pushed.
. The scan does not

Solution
Set the SIMPLEX/DUPLEX
Switch to the "SIMP" position.
Set the SIMPLEX/DUPLEX
Switch to the "DUP" position.
Set the proper frequency split
and set the DUPLEX MODE
Switch to the "NOR" ог "REV"
position, or the OFFSET Switch
to the "+" or "—" position ac-
cording to repeater input/output
frequency.
Use the continuous operating
power source ог optional
memory power source.
Program the required frequencies
in the memory channels follow-
ing the instructions for "MEMO-
RY CHANNEL OPERATION"
on page 13.
Set the VFO/MEMORY CHAN-
NEL Switch in a Memory
Channel position.
Program the low edge frequency
into the memory channel 1, and
the high edge frequency into the
memory channel 2.
Set the VFO/MEMORY CHAN-
NEL Switch in the VFO position.
Engage the squelch on a nosignal
frequency, then start the scan by
pushing the S/S Switch.
