Maintenance
Under normal circumstances the product does not need any special maintenance.
Should the unit become dirty, swipe it with a clean damp cloth. Do not use solvent or
strong detergents.
Trouble shooting
If the loop amplifier does not perform satisfactory, check the following:
Does the mains power indicator light? If not, control that the transformer is correctly
connected to the power outlet and to the amplifier.
Does the loop current indicator light? As this indicator lights it's a guarantee that the
system works. If not, check that the loop pad, sofa or room loop is not broken and correctly
connected. Check also all other connections.
Attention! If headphones are connected the loop current indicator is disabled.
The loop current indicator lights but there is no sound in the hearing aid/headphones:
check that the M-T-O switch of the hearing aid is in T or MT mode. Also check the status of
your hearing aid batteries.
Bad sound quality? Adjust the loop current, bass and treble controls. Bass and treble
adjustment should normally not be needed.

Should the system not work after having made the product test as described above, please
