Solving Problems with the Remote
Control
The projector doesn’t respond to remote control commands.
■ Make sure the remote control is turned on.
■ Make sure you are within 30 feet 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).
■ The remote control batteries may not be installed correctly or may
be low on power. To test the batteries, press the
light button.
The other buttons on the remote should light up temporarily. If
they don’t, you need to change the batteries as described on
page 28.
■ 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 can’t control the mouse pointer with the remote
control.
■ Make sure the mouse cable is securely connected to both your
computer’s mouse port or USB port and the projector’s mouse
port. For details, see page 13 (for laptops) or Appendix A (for
other systems).
■ To use the USB mouse connection on a PC, your system must
have a “clean” installation of Windows 98 (SR2), Windows Me,
or Windows 2000. The connection may not work correctly if
your system was upgraded from Windows 95. [TRUE?]
