Adjustment tips for the configuration menu
Switching the internal microphone on or off (receiver only)
INT.MIC The EK 2015 receiver has an internal microphone that picks up environmen-
tal 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)
FADE 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 micro-
phone is reduced during speech transmission. The speaker has automatic
priority over environmental sounds, providing for better speech intelligibil-
ity with the receiver. 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 cir-
cuit 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 inter-
fering noise such as banging doors do not trigger the automatic priority cir-
cuit.
Adjusting the squelch threshold (receiver only)
SQELCH The receiver is equipped with a squelch that can be adjusted via the
“
SQELCH ” menu. The squelch eliminates annoying noise when the trans-
mitter 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:
y
LO =low
y
MID =middle
y
HI =high
