Maintenance
A lamp has a finite product life. Using the lamp for long periods of the time could
cause the picture to become darker or the color tone to become poor. Note that
each lamp has a different lifetime, and some may burst or burn out soon after you
start using them.
Preparation of a new lamp and early replacement are recommended. To purchase
a new lamp, contact your dealer and tell the lamp type number = DT00665.

Turn the projector off, and unplug the power cord. Allow the projector to cool
for at least 45 minutes.
