PROBLEM
POSSIBLE CASE
SOLUTION
REF.
TRANSMIT
Transmitting is impos-
sible.
• The operating frequency is not set in a
ham band.
• Set the frequency in a ham band.
p. 25
Output power is too
low.
• Power is set to a lower power than max-
imum.
• Set the output power in quick set mode.
p. 71
• Microphone gain is set too low.
• Set microphone gain to a suitable level
in quick set mode.
p. 71
• The antenna is not connected properly.
• Reconnect the antenna connector.
—
• The antenna feed line is cut or shorted.
• Check the feed line and correct any im-
proper conditions.
—
• The antenna is not properly tuned.
• Push
TUNER
to manually tune the an-
tenna or test with dummy load.
p. 67
• The antenna for another band is se-
lected.
• Select an antenna suitable for the oper-
ating frequency.
p. 67
No contact possible
with other stations.
• RIT function is activated.
• Push
RIT
to turn the function OFF.
p. 44
• Split function is activated.
• Push
SPLIT

for 1 sec. to deacti-
vate the function.
p. 29
• The internal CPU has malfunctioned.
• Reset the CPU.
pgs. 21,
84
SCAN
Programmed scan
does not stop.
• [RF/SQL] is assigned to RF gain control
and squelch is open.
• Reset [RF/SQL] control assignment and
set it to the threshold point.
p. 30
Programmed scan
does not start.
• The same frequencies have been pro-
grammed in scan edge memory chan-
nels.
• Program different frequencies into scan
edge memory channels.
p. 62
Memory scan does not
start.
• 2 or more memory channels have not
been programmed.
• Program 2 or more memory channels.
p. 62
MEMORY
The memory channels
cannot be selected
with rotating the [M-CH]
control.
• The [M-CH] control acts as the RIT con-
trol mode.
• Push
M-CH/RIT
SET
to set the
[M-CH]
con-
trol to memory channel control. (RIT
control indicator goes out).
