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 1 minute until the intake and exhaust fans for cooling

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-HC9000LP. Use of other lamps may cause a failure of the projector.
