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 106.
■ 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 you can’t adjust the room lighting, you can turn off one of the
remote receivers by using the Settings menu. Make sure the
receivers are not both turned off (see page 66).
■ Check to see if a button on the remote control is stuck down,
causing it to enter sleep mode. Release the button to wake the
remote.
■ If you want to use the remote control as a wireless mouse (or to
move through presentation slides), make sure
USB Type B in the
Extended menu is set to Wireless Mouse (see page 68). Also,
make sure you have connected the USB cable.
