6.3 Sensitivity
■
The sensitivity of the microphone can be adjusted in two steps with the SENSITIVITY switch (upper
position: high sensitivity, central position: low sensitivity). Thus, the volume level of the microphone can
be readjusted. Reduce the sensitivity if the volume of the microphone signal is too high and thus
distorted. Increase the sensitivity if the volume is too low and a poor S/N ratio results.

will be transmitted.

automatically after a short time, keep buttons ON/OFF, SET
▲
and

pressed simultaneously, until the

n

these measures of if other malfunctions occur, remove the batteries and reinsert them.
