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

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.
