Note

The projector consumes about 6W of power in standby. We recommend you to unplug the AC power cord if you will not use the projector for an extended period.

PRECAUTIONS

• Before unplugging the AC power cord, make sure that the LAMP indicator is off.

Unplugging the AC power cord and cutting off the power while the projector is running or

being cooled will shorten the life of the lamp. However, please unplug the AC power

cord if the projector locks up or acts abnormally.

Operations

WARNING

• Do not look into the lens during operation. Doing so could damage your vision.

CAUTION

Do not block the air intake or exhaust. Doing so could cause a fire due to internal overheating.

Do not place your hands, face, or other objects near the air exhaust. Doing so could cause burns, deform/break the object.

Notes

The start-up screen will disappear after a moment. You can dismiss the start-up screen before this by performing any operation. You can also configure the start-up screen not to appear via the Display setting menu p.31 .

The first time you use the projector after purchase, after the start-up screen disappears, the Language menu is displayed p.22 .

• If the AC power cord was unplugged before cooling was complete, give the lamp

sufficient time to cool before plugging it back in. If the lamp overheats, it may fail to light,

and its lifetime will be shortened.

LCD Panels

LCD panels wear out. In order to prolong the lifetime of your LCD panel, take the following precautions.

In order to extend the lifetime of the LCD panel, always turn off the power when not in use, and make sure that the lamp is off. Keeping the lamp off is also very effective at saving electricity.

If the air filter becomes dirty and clogged, the projector’s internal temperature will rise, shortening the lifetime of the LCD panel and causing malfunctions. Clean the air filter from time to time p.32 , and replace it periodically. Contact the store where you purchased your projector, or your local Service Station for replacement air filters.
