WARNING
• For disposal of used lamp, treat according to the instruction of
community authorities.
• Since the lamp is made of glass, do not apply shock to it and do
not scratch it.
• Also, do not use old lamp. This could also cause explosion of the
lamp.
• If it is probable that the lamp has exploded (explosive sound is
heard), disconnect the power plug from the power outlet and ask
your dealer to replace lamp. 
The lamp is covered by front glass , but, in rare cases, the
reflector and the inside of the projector may be damaged by scattered broken pieces of
glass, and broken pieces could cause injury when being handled.
• Do not use the projector with the lamp cover removed.
MAINTENANCE
Lamp
HIGH VOLTAGE
HIGH TEMPERATURE
HIGH PRESSURE
Contact your dealer before replacing the lamp.
(Option lamp: DT00331)
Before replacing the lamp, switch power OFF, remove the power cord from the power outlet, and
wait approximately 45 minutes until the lamp has cooled. The lamp may explode if handled at high
temperatures.
Lamp Life
Projector lamps have a finite life. The image will become darker, and hues will become weaker,
after a lamp has been used for a long period of time. 
Replace the lamp if the LAMP indicator is red, or the CHANGE THE LAMP message (see P.20

NOTE:
The LAMP indicator is also red when the lamp unit reaches high temperature. Before replacing the
lamp, switch power OFF, wait approximately 20 minutes, and switch power ON again. If the LAMP
