Other Precautions

This projector is made of precision components. Failure to observe the following precautions can
result in inability to correctly save data and malfunction.
 Never use or store the projector in the following locations. Doing so creates the
risk of malfunction of and damage to the projector.
 Locations subjected to electrostatic charge
 Locations subjected to temperature extremes
 Locations where there is extreme moisture
 Locations subjected to sudden temperature changes
 Locations where there is a lot of dust
 On a shaky, slanted, or otherwise unstable surface
 Locations where there is the danger of getting wet
 Locations where there are large amounts of oil smoke or other smoke
 Locations where there is the risk of salt damage
 Locations where corrosive gas (such as the sulfur gas at hot springs) is generated
 Never use the projector in an environment where large amounts of oil smoke are
present. In particular, ceiling or wall mounting the projector in an environment
where large amounts of oil smoke are present can result in the projector falling
from its mounting.
 Ensure that the remote control signal receiver is not exposed fluorescent light,
sunlight, or other strong light. Strong light can cause malfunction.
 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.
