Microphone sensitivity
If the main unit is placed close to a sensor or external microphone,
the audio signal will be picked up by the microphone. The signal
will continue then until the main unit is switched off, i.e. there will be
feedback.
Adjust the microphone’s sensitivity with the set screw on the side of
the sensor until the audio signal does not affect the sensor.
Turn the control clockwise to increase sensitivity and anticlockwise to
reduce it.

Please note!
The risk that the audio signal will cause feedback is particularly great
if the audio signal is set on high or increasing signal while using the
internal microphone.
If you are using the high audio signal we recommend using an
external microphone.
