Operation
1. Before you insert the power cord into
the designated socket on the rear panel
of the inductive loop amplifier, set the
volume control to its lowest setting.
2. Press the Power on/off button (7) to
switch the loop amplifier on.
3. Now anyone wearing a hearing aid must
set it to the T or MT position.
4. Adjust the volume control to the desired
volume.
Important: Before you connect or discon-
nect an audio source, always pull the power
cord out of the wall outlet.
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.
- Make sure that the volume is set correctly.
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 wea-
ker the signal will become.
Sound distortion
- Loop volume is set too high. Turn the vol-
ume down.
- Connection cable is damaged. Replace
the cable.
Background noise (humming)
- Switch the loop amplifier off and if the
noise continues, this indicates interfer-
ence caused by another device, such
as the TV, neon lights or dimmer switches.
- 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 microphone.
