Remote Control Information

You can operate the projector by remote control via a line-of-sight infrared

(IR) receiver at the front and rear of the projector. The projector may not

respond to remote control commands under the following conditions:

■ There is an object between the remote control IR emitter and the IR

receiver on the projector.

■ Ambient light is too bright.

■ Certain types of fluorescent lighting are used.

■ A strong light source shines into the IR receiver.

■ Other equipment that emits infrared energy, such as a radiant room

heater, is in the room.

These conditions commonly cause problems for most infrared-controlled

equipment. Try the following:

■ The remote control unit’s battery may be low on power; replace it.

■ Dim the ambient lighting and/or turn off any fluorescent lights.

■ Close any window coverings and/or move the projector out of direct

sunlight.

■ Turn off other equipment that emits infrared energy.

If the remote control still does not work correctly, you can always run your

computer-based presentation directly from the computer.
