| 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
