Trouble Shooting Guide
No Sound
Check Amplifier is plugged into power source and power switch illuminates when on.
If the power point is tested OK with another appliance and the amplifier does not
illuminate when turned on refer to qualified service personnel.
If the amplifier has power, press the “bell” button to see if there is visual indication of
sound on the V.U. Meter. If there is no indication of sound refer to qualified service
personnel.
Test other input sources for indication of sound on the V.U. Meter. Check the relevant
volume controls are turned on. If there is no indication of sound from any source,
refer to qualified service personnel.
If there is no indication of sound from any one source the problem is more than likely in
that source.
If the amplifier shows visual indication of sound ie. the amplifier is not working but still
no sound out over the installation, the problem may be external to the amplifier and
should be referred to qualified service personnel.
Squealing
When microphone talk button is depressed. This is caused by the microphone being
too close to the loudspeaker.
Distortion
Or insufficient level of sound from any one source.
Adjust relevant volume control for that particular source.
NOTE
There are no user controls, adjustments, or serviceable items inside the amplifier
case. Fuses on the rear panel should be replaced by qualified service
personnel after investigation of the cause of the fuse failure.
