Ascotel® DECT System
Switching Microphone On/Off
In a call connection with another test HA or in a loopback connection of a test HA,
the microphone can be switched off and on:
1. Press "M" repeatedly until "Micro" appears
2. Press Foxkey "Micro":
Microphone is switched off and the symbol "n" is displayed.
3. Press Foxkey "Micro" again:
Microphone is switched on and the symbol "n" disappears.
Switching Hands-free Operation On/Off
The hands-free operation can be switched on and off in a call connection with
another HA. This has the advantage that the call quality can be simultaneously
checked visually and acoustically:
1. Press the loudspeaker key:
Hands-free operation is activated. The symbols "o" and "l" are displayed
2. Press the loudspeaker key again:
Hands-free operation is deactivated. The symbols "o" and "l" disappear.
Notes:
In the hands-free mode, the send path is switched through in a loud
environment and the reception path is greatly attenuated. To prevent
this, the microphone can be switched off also in the hands-free mode.
In a loopback connection, the hands-free mode makes no sense (feedback
or suppression of the signal).
