Adjustment tips for the configuration menu

Switching the internal microphone on or off (receiver only)
The EK 2015 receiver has an internal microphone allowing persons with
hearing problems to hear environmental sounds. The internal microphone
can be switched on or off on via the "INT.MIC" menu.
Adjusting the gain reduction of the automatic priority circuit (receiver only)
The receiver is equipped with an automatic priority circuit. This ensures that
the gain of the hearing aid microphones or of the receiver's internal
microphone is reduced during speech transmission. The person with the
hearing problems thus hears the speaker more than he hears environmental
sounds. The internal microphone in the receiver has a preset gain reduction.
For the hearing aid microphones, in contrast, you can adjust the gain
reduction via the "FADE" menu. The higher the set value, the greater the gain
reduction. In the "OFF" setting, the automatic priority circuit is switched off,
i.e. the gain of the microphones is not reduced while the speaker is talking.
A speech filter completes the automatic priority circuit, ensuring that
interfering noise such as banging doors do not trigger the automatic priority
circuit.
Adjusting the squelch threshold (receiver only)
The receiver is equipped with a squelch that can be adjusted via the "SQELCH"
menu. The squelch eliminates annoying noise when the transmitter is
switched off. It also suppresses sudden noise when there is no longer
sufficient transmitter power received by the receiver.
There are three possible squelch settings:
LO = low
MID = middle
HI = high
Selecting the setting "LO" reduces the squelch threshold, selecting the
setting "HI" increases the squelch threshold. Adjust the squelch threshold –
with the transmitter switched off – to the lowest possible setting that
suppresses hissing noise.
