 Avoid using the projector under the following conditions. Such conditions create
the risk of malfunction of and damage to the projector.
 Avoid areas subject to temperature extremes (operating temperature range is 5°C to 35°C (41°F
to 95°F)).
 Never place heavy objects on the projector or climb on top of the projector.
 Never insert or allow foreign objects to drop into the projector.
 Never place a vase or any other container of water on top of the projector.
.
 Whenever setting the projector down or performing any operation that
involves moving or reorienting it, take care that you do not pinch your
fingers under the projector.
 To avoid running down the batteries, store the remote control unit so its keys are
not pressed inadvertently.
 Never leave dead batteries inside the remote controller for a long time.
Dead batteries can leak, which leads to malfunction of and damage to the remote controller. Be sure
to replace the batteries at least once every one year, no matter how much you use the remote
controller during that time.
 Clean with a soft, dry cloth.
When very dirty, use a soft cloth that has been dampened in a weak solution of water and a mild
neutral detergent. Wring all excess water from the cloth before wiping. Never use thinner, benzine, or
any other volatile agent to clean the projector. Doing so can remove its markings and cause staining of
the case.
 Missing Screen Dots
Though this projector is manufactured using the most advanced digital technology available today,
some of the dots on the screen may be missing. This is normal, and does not indicate malfunction.
 Never subject the projector to strong impact while it is projecting.
If the projector is accidentally subjected to strong impact, the projection image will momentarily go
blank. The image will reappear after some time, but it may be the wrong color or it may be
accompanied by an error message.
If the projected image is the wrong color, turn projector power off and then back on again.
If the image reappears with an error message, correct the problem in accordance with the indicator
explanations under "Error Indicators and Messages" (page 70).
 Use a power outlet near the projector. Always use the projector so that the power
cord can be easily unplugged.
 The YW-41 Wireless Adapter (included or purchased separately) supports the
2.4GHz band only.
