Maintenance 5-3
REPLACING THE LAMP
For best performance, you should replace the lamp after 700 hours of
operation.
Note: Do not touch the lamp with your bare hands. Use gloves or a soft cloth
and handle it using the metal ends only.
Removing the old lamp
1 Leave the projector running with the lamp off for at least five minutes
before you change the lamp. This allows the fan to cool the lamp
chamber.
2 After the lamp has cooled sufficiently, turn off the projector and unplug
the power cord. (As a safety feature, the lamp chamber can’t be opened
until the power cord has been removed.)
3 Slide the AC lock button in the direction of the arrow. This button will
not move unless the power cord has been disconnected from the
projector.
4 While sliding the AC lock button, remove the left side cover by sliding it
about 1/4 of an inch to the left. When the cover releases, pull it straight
off (see Figure 5-2).
