9 Series Decoding Computer System Operation 
Once the 931 Digital Controller and 921 Mono Decoding Computers are configured 
and installed in your system, all operation is done by using the remote control and 
display screen on the 931 Digital Controller. 
Front Panel Controls 
There are five buttons on the front panel of the Wadia 931. 
During configuration mode, these buttons change functions (see Configuration). 
UP/Down: These buttons perform the same function as the volume up and volume 
down keys on the remote control. The volume is increased or decreased by 1 (0.5 
dB). The volume control range is from 1 (-50 dB) to 100 (0 dB). Setting the volume 
to zero completely mutes the output. 
Left/Right: Scrolls to the next or previous enabled input in numerical order. 
Enter: Scrolls to the next menu screen.
