Troubleshooting (Continued)
PROBLEM
The transceiver
automatically switches to
transmit while receiving.
Cannot contact with
another station, even if
receiving and transmitting
seem normal.
Received audio in the
SSB mode is unclear or
distorted.
Transmit signal is unclear
or distorted in the SSB
mode.
The operating frequency
is not properly changed by
rotating MAIN DIAL .
Programmed scan does
not start.
Memory scan does not
start.
Select memory scan does
not start.
The contents of a selected
memory channel is not
changed.
Cannot hear the speech
after pushing .
SPEECH
The antenna SWR is too
high.
"OVF" is displayed.
The touch screen is not
working correctly.
POSSIBLE CAUSE
The VOX function is ON.
The VOX gain is set too high.
The Split function is activated.
( The transmit and receive frequencies
are different.)
The RIT function or the ∂TX function
ON, and a different receive or transmit
frequency is set.
The incorrect sideband is selected.
The PBT function is activated.
The transceiver's microphone gain is too
high.
The desktop microphone gain is too high.
The Dial Lock function is activated.
The same frequencies have been set in
scan edge memory channels P1 and P2.
No, or only 1 memory channel is set.
No, or only 1 memory channel is
designated as a Select channel.
The contents of the selected memory
channel were changed, but they are not
saved.
The speech level is too low.
The antenna is not properly tuned.
The coaxial cable is not suitable.
An excessively strong signal is received. Rotate
The touched point and the detected point
may be different.
SOLUTION
Turn OFF the VOX function in the Multi-
function menu.
Adjust the VOX gain.
Push to turn OFF the Split

function.
Toggle between USB and LSB.
Rotate

CLR
Adjust the MIC GAIN level so that the
meter reading swings between 30 and
50% of the ALC scale.
Hold down
SPEECH
Lock function OFF.
Set different frequencies in scan edge
memory channels P1 and P2.
Set at least 2 memory channels.
Designate at least 2 memory channels
as Select channels for the scan.
When you want to save the changed
settings, touch [MW] for 1 second to
write them into the memory channel on
the VFO/MEMORY screen.
Adjust "SPEECH Level" in the Speech
setting.
Adjust the antenna SWR.
The antenna SWR should be less than 3.
Use a coaxial cable whose characteristic
impedance is 50 Ω.
