Selects the acoustic signal to represent the level, the tone
of which varies with the power received, also:
In Monitor mode it activates the measurement bar and the
representation of the synchronism pulse.
In Spectrum Analyser mode, SPAN mode, it activates the
C/N measurement bar.
Selects television sound demodulation, permits the volume
to be altered, and eliminates the measurement information
