If the projector continues to overheat after you clean the air filter,
the problem may be caused by damage to the cooling fan or internal
circuits. Contact a qualified service person.
Warning: Don’t attempt to perform any servicing other than the
maintenance procedures explained in Chapter 5.
Problems with the Remote Control
w
The projector doesn’t respond to remote control commands.
The remote control may be too far from the projector, or at too wide
an angle to the infrared receiver. See page 59 for details.
The remote control’s batteries may be low on power. Replace them.
If you are using the remote as a wireless mouse, make sure the
projector’s mouse cable is securely connected to both your
computer’s mouse port and to the projector’s Mouse/COM port (or
the main cable if you are using ELP Link III). For details, see
Chapter 1 (or Chapter 4 for ELP Link III).
Light that is too strong, or certain types of fluorescent lighting may
affect the projector’s infrared receivers. Dim the ambient lighting
and turn off any fluorescent lighting. Move the projector out of
direct sunlight.
Turn off any nearby equipment that emits infrared energy, such as a
radiant room heater.
