•
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.
