The projector is equipped with two outputs (Voltage: 12
Vdc) for motorised projection screen and screen masking
systems. These 12V outputs should be connected to the
appropriate screen interface provided by the screen

The +12V output is activated when the projector is
switched on (green LED on) and is de-activated when the
projector is in stand-by mode (red LED on).
The output is active when one of the following modes,

Menu.
This output allows reduction in the area of a 16:9 screen,
