6. Troubleshooting

Minor Troubleshooting

Most of VHF troubles are caused not by the transceiver itself but by the ANT/feeder or power supply

system. The list below provides simple troubleshooting that can be done by the operator. DO NOT

ATTEMPT TO CHECK INSIDE THE TRANSCEIVER. CARELESS HANDLING MAY CAUSE

PERMANENT DAMAGE TO THE TRANSCEIVER.

Symptom

Possible Cause

Remedy

Power is off at mains switchboard.

Turn mains switch on.

Power lead is loose or disconnect.

Secure connector firmly and check

connections to battery.

Mains battery is flat.

Check battery liquid, charging

system, etc.

Volume control turned

clockwise but power

does not come on.

Fuse has blown.

Check mains voltage and polarity

and then replace fuse (10A).

SQUELCH setting is too high.

(Turned too far clockwise.)

LCD looks

normal but no sound.

VOLUME setting is too low.

To confirm audio output, turn

SQUELCH fully CCW and turn

VOLUME slowly CW.
