Turning On or Off Remote Sensor [REMOTE SENSOR]
This option determines which remote sensor on the projector is enabled in wireless mode.
The options are: FRONT/BACK, FRONT, BACK, and HDBaseT*.
NOTE:
• The remote control of the projector will not be able to receive signals if the power supply of the HDBaseT transmission device
connected to the projector is switched on when this has been set to "HDBaseT".
TIP:
• If the remote control system does not function when direct sunlight or strong illumination strikes the remote control sensor of
the projector, change to other option.
