■ Dim the room lights and turn off any fluorescent lights. Make
sure the projector is not in direct sunlight. Strong lighting,
especially fluorescent lights, may affect the projector’s infrared
receivers. Also, turn off any nearby equipment that emits infrared
energy, such as a radiant room heater. To avoid interference, you
can also turn off the projector’s front or back sensor with the
Remote Receiver setting (see page 57), but this may limit where
you can use the remote control.
■ Make sure the projector’s sensors have not been turned off with
the
Remote Receiver setting (see page 57).
■ If the projector ID has been set, you may need to change the
projector or remote control ID. See page 37.
■ If any buttons are held for longer than 30 seconds, the remote
enters sleep mode. Release any button that is held to wake the
remote.
