WARNINGS:		Lamp
• Dispose of the used lamp according to local regu-
lations.
• 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 the
lamp to explode.
• 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.	Reflector	Front Glass

Lamp Life

Projector lamps have a finite life. The projected images will become darker and hues will become weaker after a lamp has been used for a long period of time.

The LAMP indicator also becomes red when the lamp unit reaches a high temperature. Before replacing the lamp, switch the POWER OFF, wait approximately 20 minutes, then switch the POWER ON again. If the LAMP indicator still displays red, replace the lamp.
