Solving Problems with the Remote
Control
The projector doesn’t respond to remote control commands.
■ Make sure the remote control is turned on using the switch on its
side (see page 50).
■ Make sure the remote control ID matches the ID of the projector
you want to operate (see page 52). If you don’t know the
projector ID, set the remote control ID to zero; this lets it work
with any projector.
■ If you’ve held down the pointer button for more than 10
seconds, the remote control may have gone into sleep mode.
Releasing the button restores normal operation.
■ The remote control’s batteries may not be installed correctly or
may be low on power. To change the batteries, see page 54.
■ Make sure you are within 30 feet (9 meters) of the projector, and
within range of the projector’s front or back sensor
(approximately 30° to left or right and 15° above or below).
■ Dim the room lights and turn off any fluorescents. Make sure the
projector is not in direct sunlight. Strong lighting, especially
fluorescent lights, may affect the projector’s infrared receivers.
■ Turn off any nearby equipment that emits infrared energy, such
as a radiant room heater.
You’ve connected a computer and you can’t control the
mouse pointer with the remote control.
Make sure the cable is securely connected to both your computer’s
USB port and the projector’s USB port (see page 31).
