No signals are
received or receive
sensitivity seems
poor; S-meter is
reading full scale.
The RF gain was set too low. Turn the RF control clockwise to increase the RF
gain.

Received signals
are completely
unintelligible
The wrong modulation was
selected.
Select the correct modulation mode. 11
Memory Scan will not
start scanning.
1 The SQL control was not
set correctly.
2 Less than 2 memory
channels were unlocked.
3 Less than 2 memory
channels were
programmed.
1 Adjust the SQL control to just eliminate
background noise.
2 Unlock at least 2 memory channels.
3 Store data in at least 2 memory channels.

Memory Scan will
not scan one of the
stored channels; the
desired channel is not
locked out.
With Group Scan selected, the
channel you want to scan is in
a different group.
Select the Memory Group that contains the
memory channel you want to scan.

Program Scan will not
start scanning.
The start and end frequencies
are identical
Store different start and end frequencies. 48
AT does not fi nish
successfully.
The impedance of the coaxial
cable and antenna was not
matched. Tuning does not
successfully fi nish depending
on conditions, although the
SWR meter indicates smaller
than 3:1.
Adjust the antenna system to lower the SWR. 52
The internal tuner is
bypassed immediately
after tuning is started.
The SWR of the antenna
system is too high.
Adjust the antenna system to lower the SWR 52
You cannot transmit
even though you
press MIC [PTT], or
transmissions result
in no contacts.
1 The microphone plug was
not inserted completely into
the MIC connector.
2 The Transmit Inhibit function
is ON.
3 CW or FSK was selected
instead of a voice mode.
4 The DSP TX fi lter
bandwidth was improperly
selected.
5 The wrong antenna
connector (ANT 1 or ANT
2) was selected.
1 Turn OFF the power, ensure the MIC
connector has no foreign objects in it, then
plug in the connector fi rmly.
2 Change Menu No. 66 to OFF.
3 Select the correct voice mode.
4 Adjust the settings in Menu Nos. 31, 32.
5 Press and hold [PRE (ANT 1/2)] to select the
other antenna connector.

Attempting to transmit
results in the “HELLO”
message appearing
and the reception
mode being restored.
1 The antenna is not
connected correctly.
2 The impedances of the
antenna and transceiver
are not properly matched.
3 The input voltage is outside
13.8 V DC ± 15% (11.7 ~
15.8 V DC).
4 The current rating of the DC
power supply is not enough.
1 Check the antenna connection. Correct as
necessary.
2 Reduce the SWR of the antenna system.
3 Correct the input voltage or use a 12 ~ 16 V
battery.
4 Use a DC power supply that has a current
rating of more than 20.5 A at 13.8 V DC.

The transceiver has
low transmission
power.
1 The microphone gain is set
too low.
2 Poor antenna system
connections are causing
high SWR.
1 When in SSB or AM mode, increase the
microphone gain.
2 Check the antenna connections. Confi rm that
the antenna tuner is reporting a low SWR.
