Replacing the lamp

This projector is equipped with a lamp to project images. This lamp is a consumable. It may burn out or its brightness may decrease during use. In such cases, replace the lamp with a new one as soon as possible. Be sure to replace the lamp with a new lamp sold separately that is exclusive to this projector. Contact your dealer for purchase of the lamp.

Spare lamp VLT-HC910LP

Warning:

•Be careful not to drop the lamp fixing screws inside of the projector. Don’t put a metal piece or flammable object into the projector. Using the projector with any foreign object present inside may result in electric shock or fire. When you can’t remove the foreign object from the inside, contact your dealer for removal.

•Be sure to install the lamp securely. When the lamp isn’t installed properly, it won’t illuminate. Improper installation may also result in fire.

•Don’t shake the removed lamp or don’t lift it above your face. Your eyes may be injured by flying or falling glass fragments.

•Don’t replace the lamp immediately after use because the lamp cover will be very hot. You may get burned. Turn off the power using the POWER button. After the lamp goes out, wait about two minutes until the intake and exhaust fans for cooling the lamp stop rotating. Then unplug the power cord, and wait at least one hour to allow the lamp to cool down enough to the touch.

•Do not touch the lamp directly. It may break and cause injury or burn.

Interval of lamp replacement

The recommended interval of lamp replacement is about 3000 hours*1*2 of consecutive use. Such interval differs depending on the operating environment and may be shorter than 3000 hours*1*2. Decrease in luminescence and/or color brightness indicates that the lamp needs to be replaced. When the lamp operation time exceeds 2250 hours*1,

the indicator will blink alternately between green and red (while the lamp is lit; when the lamp is not lit, the indicator will be lit red only) and the lamp replacement message will appear on the screen for one minute everytime the lamp is turned on. When the lamp has been used for about 2850 hours*1, the replacement message (LAMP EXCHANGE) will

appear on the screen for one minute every 15 hours*1 thereafter.

When the lamp operation time exceeds 3000 hours*1*2, the projector automatically shuts off and can’t be used until the lamp is replaced and the lamp operation time is reset.

*1 Duration when LAMP MODE of the INSTALLATION menu is set to LOW. When it is set to STANDARD, this duration will be shorted.

*2 Duration when LAMP MODE is set to STANDARD, this duration will be shorted to 2000 hours.

Caution:

•Don’t remove the lamp for any purpose other than replacement. Unnecessary removal of the lamp may result in a breakdown.

•This projector uses a high-pressure mercury lamp as the light source. The high-pressure mercury lamp may explode or fail to illuminate permanently because of an impact, scratch, or deterioration through use. The period of time until explosion or permanent failure to illuminate varies considerably from lamp to lamp, depending on operation conditions. Therefore, the lamp may explode soon after the start of use.

•The possibility of explosion of the lamp increases if you use it beyond its replacement period. When the instruction of lamp replacement appears, replace it with a new one immediately even if the lamp is still lighting normally.

•When the high-pressure mercury lamp explodes, glass fragments will scatter inside or outside the lamp box and the gas charged inside the lamp will diffuse inside or outside the projector. The gas inside the lamp contains mercury. Be careful not to breathe it or avoid it from entering your eye or mouth. If you should breathe it or if it should enter your eye or mouth, see a doctor immediately.

•In the event that the high-pressure mercury lamp exploded, glass fragments may have been scattered inside the projector. Ask your dealer to replace the lamp and to inspect the inside of the projector. When you clean or replace the lamp by yourself, be sure to hold the handle of the lamp. You may get injured by glass fragments.

•Don’t replace the lamp while the projector is installed on the ceiling. Glass fragments may fall from the projector, entering your eye or mouth causing injury.

•When placing the projector upside down to replace the lamp or conduct maintenance, ensure that the projector is securely placed before working with it.

•Be sure to use the lamp exclusive to this projector, VLT-HC910LP. Use of other lamps may cause a failure of the projector.
