MAINTENANCE
Lamp
To order a new lamp unit (Lamp Part # PRJ-RLC-001), contact ViewSonic or your dealer. For the
lamp part number, see the Optional Parts in the Specifications in this guide. For contact information,
see the Customer Support table in this guide. Before replacing the lamp, turn the Power Switch OFF,
remove the power cord from the power outlet, then wait approximately 45 minutes until the lamp has
cooled.
CAUTION: The lamp may explode if handled at high temperatures.
WARNINGS:
• 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.
• Do not use the projector with the lamp’s front
glass covering removed.
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.
