MAINTENANCE MAINTENANCE
Lamp
HIGH VOLTAGE
HIGH TEMPERATURE
HIGH PRESSURE
Contact your dealer before replacing the lamp.
For the optional lamp, see the item “Accessories” of P.24.
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 appears
when the projector is switched ON. See Table 9 of P.20 and Table 10 of P.21.
•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 indicator is still red, replace the lamp.NOTE
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.
