Troubleshooting
No sound
- Check to make sure that all the cables
are connected properly.
- Make sure that the amplifier is switched
on.
- Make sure that the hearing aid is set to
the "T" or "MT" function.
Volume level is not loud enough
- The volume control is set too low.
Turn up the volume on the amplifier.
- The Line Input control is set too low.
Turn up the line input control.
- Make sure that you are sitting up fairly
straight. The more you lie down, the
weaker the signal will become.
Sound distortion
- Loop volume is set too high. Turn the
volume down.
- Connection cable is damaged. Replace
the cable.
Background noise (humming)
- Switch the loop amplifier off and if the
noise continues, this indicates inter-
ference caused by another device, such
as the TV, neon lights or dimmer swit-
ches.
- If the noise disappears when the loop
amplifier is switched off, the
problem might be a system error, a
damaged microphone cable or a noise
that is being transmitted by the micro-
phone.

nical shocks.
