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:

yLO =low

yMID =middle

yHI =high
