NEC WT600 - Manual (Page 63)

7-1
This section describes the simple maintenance procedures you
should follow to replace the lamp, and to clean the cabinet and
the mirror.
7-1. Replacing the Lamp
After your lamp has been operating for 2000 hours (up to 3000
hours : Eco mode) or longer, the "Lamp" indicator in the cabinet
will blink red and the message will appear. Even though the lamp
may still be working, replace it at 2000 hours (up to 3000 hours
: Eco mode) 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
90 seconds, turn off the main power switch, and then dis-
connect 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 receive an
electric shock.
• The projector will turn off and go into stand by mode af-
ter 2100 hours (up to 3100 hours : Eco mode) of service.
If this happens, be sure to replace the lamp. If you con-
tinue to use the lamp after 2000 hours (up to 3000 hours :
Eco mode) of use, the lamp bulb may shatter, and pieces
of glass may be scattered in the lamp housing. Do not
touch them as the pieces of glass may cause injury.
If this happens, contact your NEC dealer for lamp replace-
ment.
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.
3. Remove the lamp housing by pulling out the handle.

5. Secure it in place with the two screws.
Be sure to tighten the screws.
6. Reattach the lamp cover.
7. Tighten the lamp cover screw.
Be sure to tighten the screw.
8. After you install a new lamp, from the menu select [Projector
Options] → [Setup] → [Page 4] → [Clear Lamp Hour Meter] to
reset the lamp usage hours.
If the projector will not be turned on after using 2100 hours
(up to 3100 hours : Eco mode) of service, press and hold the
[Help] button on the remote control for ten seconds or longer
to reset the lamp time clock to zero.
NOTE: There is an interlock on this case to prevent the risk of electri-
cal shock. Do not attempt to circumvent this interlock.
4. Insert a new lamp housing until the lamp housing is plugged
into the socket.
CAUTION: Do not use a lamp other than the NEC replace-
ment lamp (LT60LPK).
