MAINTENANCE
This section describes the simple maintenance procedures you
should follow to replace the lamp, clean or replace the filter, and
replace the batteries in the remote control.
Replacing The Lamp
After your lamp has been operating for 2000 hours or
longer, the "status" light in the cabinet will go on. Even
though the lamp may still be working, replace it at 2000
hours to maintain optimal projector 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 go into stand by mode after
2100 hours of service. If this happens, be sure to replace
the lamp. If you continue to use the lamp after 2000 hours
of use, the lamp bulb may shatter, and pieces of glass may
be scattered in the lamp case. Do not touch them as the
pieces of glass may cause injury. If this happens, contact
your NEC dealer for lamp replacement.
To replace the lamp:
1. Loosen the single screw that secures the lamp housing cover
and remove the cover.
2. Loosen the two screws securing the lamp case.
3. Remove the lamp by pulling out the complete assembly.
4. Install a new lamp case assembly and secure it in place with
the two screws.
CAUTION: Do not use a lamp other than the NEC replace-
ment lamp.
Order this from your NEC dealer using your projector's
model number.
5. Reattach the lamp cover and tighten the single screw.
6. After you install a new lamp, select the lamp Usage icon and
press and hold the "Power On" button on the remote control
for ten seconds to reset the lamp time clock to zero.
NOTE: If resetting the lamp clock back to zero after 2100 hours
of service, press the "Power Off" (not "Power On") button on
the remote control for ten seconds .
NOTE: When you replace the lamp, it is also wise to replace
the filter. The filter comes in the same package with your
replacement lamp.
