■
Do not store the projector outside of the required temperature
range (14 to 140 °F) or in direct sunlight for long periods of time.
Doing so may cause damage to the case.
■
Do not use the projector with the lens cap in place. The heat
generated by the lens may damage the cap.

The liquid crystal display panel contains more than 99.99% active
pixels. However, 0.01% of the pixels may be missing or constantly
illuminated.
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 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.
If the remote control still does not work correctly, you can always run
your computer-based presentation directly from the computer.
