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’s batteries may be low on power; replace them.
■ 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.
