Adjusting the radio microphone’s input sensitivity
The input sensitivity is adjusted too high when close talking distances or
speakers with loud voices cause overmodulation in the transmission link� When
the audio input level is excessively high, the audio level display (AF)

shows
full deflection�
If, on the other had, the input sensitivity is adjusted
too low
, the transmission
link will be undermodulated, which would result in a signal with high back-
ground noise�
The input sensitivity is
correctly
adjusted when the audio level display (AF) only
shows full deflection only during the loudest passages�
