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
ÒstatusÓ 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.
MAINTENANCE 4
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 replacement lamp.
Order this from your NEC dealer using your projectors 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.Step 1A

Cleaning Or Replacing The Filter
The air-filter sponge keeps the inside of the MultiSync MT830/1030 LCD Projector free from dust or
dirt and should be cleaned after every 100 hours of operation (more often in dusty conditions). If the
filter is dirty or clogged, your projector may overheat.
NOTE:  Clean your filter after every 100 hours of operation.
CAUTION
¥ Turn off the main power and unplug the projector before replacing the filter.
¥ Only clean the outside of the filter cover with a vacuum cleaner.
¥ Do not attempt to operate the projector without a filter cover.
¥ Your LCD projector will not operate unless the filter cover is installed correctly.
To clean the air-filter:
Vacuum the filter through the filter cover.
To replace the air-filter:
1. Remove the filter cover by pushing up on the catch of the cover with a flat-head screwdriver until
you feel it detach.
2. Reinstall the new filter cover.
NOTE:Do not detach the sponge from the filter cover. Do not wash the filter cover with soap and
water. Soap and water will damage the filter membrane.
Before replacing the filter cover, remove dust and dirt from the projector cabinet. Keep out
dust and dirt during filter replacement.
Remote Control Battery Installation
1. Press firmly and slide the battery cover off.
2. Remove both old batteries and install new ones (AA). Ensure that you have the batteries polarity
(+/Ð) aligned correctly.
3. Slip the cover back over the batteries until it snaps into place.
