AUDIO OUT
The projector is equipped with two outputs (Voltage: 12 Vdc) for motorised projection screen and screen masking systems, used for masking off the projection area to match the projected image aspect ratio (Fig. 17).
The +12V output is activated when the projector is switched on (green LED on) and is

The projector can be controlled from a PC: simply hookup the interface connector to a PC’s RS232 serial cable.
8 REMOTE CONTROL
The remote control requires four 1.5 V batteries, size AAA. Insert the batteries, taking care to match the polarity, as indi- cated in the battery compartment in the handset (Fig. 23). Change the batteries in the remote control if experiencing difficulty in sending commands to the projector.
Remove batteries from the remote control if it is not to be used for a long period of time. The batteries are prone to leak and corrode the remote control’s circuits.
The remote control sends commands to the projector via infrared signals.
The projector is equipped with an infrared sensor on its front panel and can therefore be controlled by pointing the remote control towards the projection screen; the IR beam reflects off the screen towards the projector (Fig. 19).
There is another infrared sensor in the rear of projector.
Do not place objects between the remote control and the receiver on the projector, as this can prevent the remote from working.
