or muted. In Windows, you may be able to check this by clicking
the volume control in your Windows system tray (lower right

volume from your menu bar (top right corner of the screen) or via
the volume control function keys.

If you’re using a DVD player or other video source, make sure the
cables are connected correctly, as described on page 35.
Solving Problems With the Remote
Control
The projector doesn’t respond to remote control commands.
■ Point the remote control towards the projector’s receiver. Make
sure you are within 19.7 feet (6 meters) of the projector and
within a 30° horizontal angle and a 15° vertical angle from the
projector’s front or back receiver.
■ The remote control’s batteries may not be installed correctly or
may be low on power. To change the batteries, see page 84.
■ 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.
■ 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.
