When an sound control is pressed, a bar scale and a number below
the bar scale appear on the screen with name of the control, e.g.
'Volume' above it. The length of the bar scale and the number
indicate the current memorised setting for this source. The bar
scale changes as the + or - buttons of the RCU control are pressed.
The appearance of the text, bar scale and number can be prevented
by pressing the 'TEXT' key. This button acts as a toggle switch,
switching between 'ON' and 'OFF' each time the button is pressed.
The latest position is memorized and is recalled when the power to
the projector is switched OFF and ON again.
The sound controls can be adjusted in 'adjustment mode' as well
as in 'operational mode'.
