[1]

0 = MOD read information indicates the modulation of the radio

channel

1 and an external input source is selected = MOD read information will

indicate the input amplitude of the selected source

6 and 5 - reserved; 0 = normal operation

4 LDON loudness on

0 = loudness control is disabled

1 = loudness control is active; loudness is controlled by the volume
