Warning:
• Be careful not to drop the lamp fi xing screws into the inside of the projector. Don’t put a metal piece or fl ammable
object into the projector. Using the projector with any foreign object present inside may result in electric shock or
fi re. 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 fi re.
• Don’t shake the removed lamp or don’t lift it above your face. You may be injured in your eye by fl ying or falling
glass fragments.
• Don’t replace the lamp immediately after use because the lamp cover is very hot. You may get burned. Turn off the
power using the POWER button. After the lamp goes out, wait about 2 minutes until the intake and exhaust fans
for cooling the lamp stop rotating. Then unplug the power cord, and wait at least 1 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 4000 or 5000 hours
*1
of consecutive use. Such interval
differs depending on the operating environment and may be shorter. Decrease in luminescence and/or color
brightness indicates that the lamp needs to be replaced. When the lamp operation time exceeds the time elapsed
until the lamp shutdown notice
*1
is issued, 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 1 minute everytime the lamp is turned on. When the lamp operation time exceeds the time elapsed until
the lamp shutdown warning

thereafter. When the lamp operation time exceeds the time elapsed until the lamp
shutdown

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.
• When removing the lamp from the ceiling-mounted projector, use the lamp replacement tray packed with the
projector or option lamp to prevent glass fragments from scattering.
• Be sure to use the lamp exclusive to this projector, VLT-XL650LP for XL2550U (or VLT-XL550LP for XL1550U). Use
of other lamps may cause a failure of the projector.
