Troubleshooting

Possible Fault

Recheck all connections.
•
Check diagrams.
•
Hearing loop driver not switched on. Switch on at mains socket.
Press mains switch. Check blue light is on.
•
Microphone or audio source not connected or selected.
•
Check Digital audio setting on TV is PCM.
•
Hearing aid not on the "T" or loop program.
•
Microphone too far from sound.

Loop cable wired incorrectly. Consult the wiring diagram and fix
any errors.

permanently. Decrease volume.
•
Audio volume set too high.
•
Move microphone away from loud speaker / adjust TV volume.
•
Microphone plug/lead damaged.
•
Using multiple inputs at the same time may lead to distorted
output, only select the inputs you wish to listen to.
•
If noise remains when the hearing loop driver is turned off but
hearing aid is still on loop program this interference is caused by
other equipment such as fluorescent lights or dimmer switches.
With the hearing loop driver turned off and the hearing aid still on
the loop programs turn items off and on until the interference can
be identified.
•
If noise stops when the hearing loop driver is turned off there may
be a fault in the system or a microphone lead or noise is being
picked up by the microphone.
