should follow to replace the lamp, clean and replace the batteries in
the remote control.
Replacing The Lamp
After your lamp has been operating for 1000 hours or longer, the
“status” light in the cabinet will go on. Even though the lamp may
still be working, replace it at 1000 hours to maintain optimal pro-
jector performance.
CAUTION
• DO NOT TOUCH THE LAMP immediately after it has been
used. It will be extremely hot. Allow at least one hour for the
lamp to cool before handling.
• DO NOT REMOVE ANY SCREWS except the lamp cover
set screw and two lamp case screws. You could receive an
electric shock.
• Turn off the main power to the projector and disconnect the
power cord. Allow at least one hour for the lamp to cool.
• The projector will turn off and be in standing by after 1100
hours of service. If this happens, be sure to replace the lamp.

checking whether the STATUS indicator is extinguished. Obtain a replace-
ment lamp at the store of purchase for this unit. When ordering a
