4. MAINTENANCE
This section describes the simple maintenance procedures you
should follow to replace the lamp, clean the filters, and replace
the batteries in the remote control.
Replacing the Lamp
After your lamp has been operating for 1000 hours (up to 2000
hours in Eco 2 mode and up to 1500 hours in Eco 1 mode) or
longer, the “Status” light in the cabinet will go on and the mes-
sage will appear. Even though the lamp may still be working,
replace it at 1000 (up to 2000 hours in Eco 2 mode and up to
1500 hours in Eco 1 mode) hours to maintain optimal projector
performance.
CAUTION
•
DO NOT TOUCH THE LAMP immediately after it has been
used. It will be extremely hot. Turn the projector off, wait
60 seconds, and then disconnect the power cable. Allow at
least one hour for the lamp to cool before handling.
• DO NOT REMOVE ANY SCREWS except the lamp
cover screw and two lamp case screws. You could re-
ceive an electric shock.
•
The projector will turn off and go into stand by mode after
1100 (up to 2100 hours in Eco 2 mode and up to 1600 hours
in Eco 1 mode) hours of service. If this happens, be sure to
replace the lamp. If you continue to use the lamp after 1000
hours (up to 2000 hours in Eco 2 mode and up to 1500 hours
in Eco 1 mode) 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 hap-
pens, contact your NEC dealer for lamp replacement.
To replace the lamp:
1. Loosen the lamp cover screw until the screwdriver goes into
a freewheeling condition and remove the lamp cover. The
lamp cover screw is not removable.
2. Loosen the two screws securing the lamp housing until the
screwdriver goes into a freewheeling condition. The two
screws are not removable.
Remove the lamp housing by pulling out the handle.
NOTE: There is an interlock on this case to prevent the risk
of electrical shock. Do not attempt to circumvent this inter-
lock.
3. Insert a new lamp housing until the lamp housing is plugged
into the socket.
CAUTION
Do not use a lamp other than the NEC replacement lamp
(VT45LP).
Order this from your NEC dealer.
Secure it in place with the two screws.
Be sure to tighten the screws.
4. Reattach the lamp cover.
Tighten the lamp cover screw.
Be sure to tighten the screw.
