6. Loosen the lamp screw to the right rear of the

Replacing the lamp
1. First, plug in the lamp cable. Be sure it is fully
seated.
WARNING
If the lamp cable is not fully seated on the
lamp plug, the lamp will not operate properly.
Overheating may occur.
2. Then mount the lamp in its place. Note the two
pins opposite the lamp screw. These fit into holes
in the optical engine.
3. Close the system following the removal steps in
reverse.
Resetting lamp hours
It is a good idea to reset the lamp hours to zero
when you install a new lamp. (See “Diagnostics:
Hours” on page 107.) This is not absolutely neces-
sary; it is just a way for you to keep track of lamp use.
How to maintain lamp life
There are some actions that can shorten lamp life:
• Turning off AC power when the lamp is on. (Turn
off the lamp with the remote and let it cool until
the fans stop; then turn off AC.)
• Turning a lamp on and off rapidly. (The lamp
should be allowed to heat up fully before turning
it off, at least three minutes.)
