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 :"OSD Messages" on page 20 and Table
10: "Indicator Messages" on page 20.
NOTE:
The LAMP indicator is also red when the lamp unit reaches high temperature. Before
replacing the lamp switch the POWER OFF, wait approximately 20 minutes, and switch the POWER
ON again. If the LAMP indicator is still red replace the lamp.

WARNINGS
• Dispose of the used lamp according to local regulations.
• Since the lamp is made of glass, do not drop the unit and do not scratch
the glass.
• Do not reuse the old lamp. This could cause an explosion of the lamp.
• If it is probable that the lamp has exploded (you have heard an explosive
sound), disconnect the power plug from the power outlet and ask your
dealer to replace the lamp. The lamp is protected by a cover glass, but in
rare cases the reflector and the inside of the projector could be damaged
by broken or shattered glass. Broken pieces of glass could cause injury.
• Do not use the projector with the lamp’s front glass covering removed.
