Precautions on handling

Precautions on transport

Make absolutely sure that the lens cap is in place when transporting the projector or carrying it around. Both the projector and the projection lens are precision-made and, as such, are susceptible to vibration and impacts. When transporting the projector and lens or carrying them around, place them in the boxes in which they were housed at the time of purchase, and take care to keep them away from vibration and impacts.

Precautions on installation

Be sure to observe the following precautions when installing the product.

Avoid installing the product in a place exposed to vibrations or impacts.

If the projector is installed in a place where vibrations are transmitted from a source of driving power and others or mounted in a car or a vessel, vibrations or impacts may be transmitted to the product to damage the internal parts, causing failure. Install the product in a place free from vibrations and impacts.

Do not move the projector while it is operating or subject it to vibration or impact.

The service life of its internal motors may be shortened.

Do not install the projector near high- voltage power lines or power sources.

The product may be exposed to interference if it is installed in the vicinity of high-voltage electrical power lines or power sources.

Do not place the projector on a vinyl sheet or carpet.

If a vinyl sheet sucked up and blocks the air filter intake port, the internal temperature of the projector may increase, which triggers the protection circuit, turning off the power.

Be sure to ask a specialized technician when installing the product to a ceiling.

If the product is to be installed hanging from the ceiling, purchase an optional hanging attachment (for high ceiling: Model No. ET-PKD56H) (for low ceiling: Model No. ET-PKD55S). Please call a specialized technician or contact an Authorized Service Center for installation.

Install the projector so that it will be supported only by its bottom panel and by none of its other parts or surfaces.

Do not place the projector over 2 700 m

(8 858.3') above sea level. When using it over 1 400 m (4 593.2') above sea level, set the “ALTITUDE”, described on page 38, to “HIGH”.

Otherwise the life of the product may be shortened. When using it over 2 700 m above sea level, consult your dealer.

Lens Focus

Do not adjust the lens focus in the initial period (within approx. 30 minutes) after switching the projector on. The high clarity projector lens is thermally affected by the light from the light source, making the focus unstable in the period just after switching on. Please allow a warm-up time of at least 30 minutes before adjusting the lens focus. Failure to do so may cause heating focus drift.

Disposal

To discard the product, call the dealer or a specialized dealer.

Precautions on use

To view clear images:

•The audience cannot enjoy high-contrast and clear images if outside light or the illumination interferes the screen surface. Draw window curtains or blinds, turn off the lightings near the screen or take other proper measures.

•Depending on where the projector is used, there are rare occasions when hot air from the air exhaust vents or the warm air from air conditioning can cause a shimmering effect on the screen. For this reason, take care not to shield the air exhaust vents and consider the direction of the air flowing from air conditioning.

Do not touch the surface of the projection lens with bare hand.

If fingerprints or stains are left on the projection lens surface, they are magnified and projected on the screen. Keep your hands away from the lens. Cover the lens with the supplied lens cap when the projector is not used.

Lamp

A mercury lamp with high internal pressure is used for the light source of this product. A high-pressure mercury lamp has the following characteristics:

•It may burst with a loud sound or end its life cycle by not illuminating because of given impacts, flaws, or deterioration due to used hours.

•The life cycle of a mercury lamp varies according to the individual difference or conditions of use.

In particular, turning the power on and off frequently and/or repeatedly will greatly affect the life cycle.

•In rare cases, it may burst shortly after the first lighting.

•The possibility of burst increases when the lamp is used beyond the replacement time.

•Lamp deterioration accelerates when used continuously for 24 hours or more. Lamp deterioration due to continuous use can be reduced by using the “LAMP RELAY” function.

Cleaning and maintenance

Be sure to remove the power cord plug from the receptacle before cleaning.

Use soft and dry cloth to clean the cabinet.

If stains are hard to remove, use a cloth dampened with a kitchen detergent solution (neutral) and squeezed to wipe the cabinet and finish with a dry cloth. If a chemical wipe is used, follow its instructions.

Do not clean the lens surface with fuzzy or dusty cloth.

If dust adheres to the lens, it will be magnified and projected on the screen.

Use a soft and clean cloth to wipe off dust.
