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.

10

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.

49

Program Scan will not

start scanning.

The start and end frequencies

are identical

Store different start and end frequencies.

46

AT does not finish

successfully.

The impedance of the coaxial

cable and antenna was not

matched. Tuning does not

successfully finish depending

on conditions, although the

SWR meter indicates smaller

than 3:1.

Adjust the antenna system to lower the SWR.

50

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

50

You cannot transmit

even though you

press MIC [PTT], or

transmissinos 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 filter

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 firmly.

2 Change Menu No. 60 to OFF.

3 Select the correct voice mode.

4 Adjust the settings in Menu Nos. 25, 26.

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.

1

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. Confirm that

the antenna tuner is reporting a low SWR.
