Solving Problems with the Remote
Control
The projector doesn’t respond to remote control commands.
■
The remote control’s batteries may not be installed correctly or
may be low on power. To change the batteries, see page 32.
■ Make sure you are within about 20 feet (6 meters) of the projector
and within range of the projector’s front or back sensor
(approximately 30° to the left or right and 30° 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. To avoid interference, you
can also turn off the projector’s front or back sensor with the
Remote Receiver
setting (see page 109), 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 109).
■ 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.
■ If you’re using the remote control as a wireless mouse, make sure
the
USB Type B
setting in the Extended menu is set to
Wireless
Mouse
(see page 118).
