Solving Problems with the Remote
Control
The projector doesn’t respond to remote control commands.
■ If you’re using the remote control for the first time, be sure to
push up on the
ON/OFF switch, as shown on page 19.
■ The remote control’s batteries may not be installed correctly or
may be low on power. To change the batteries, see page 34.
■ Make sure your remote control’s ID is set to 0, or to the
projector’s ID. See page 135.
■ Make sure you are within about 30 feet (10 meters) of the
projector, and within range of the projector’s front or back sensor
(approximately 30° to the left or right and 15° above or below).
■ 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.
