MAINTENANCE

This section describes the simple maintenance procedures you should

follow to replace the lamp, and to clean the cabinet and the lens.

Replacing the Lamp

After your lamp has been operating for 1500 hours (up to 2000 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 work-

ing, replace it at 1500 hours (up to 2000 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 disconnect the power

cable. Allow at least one hour for the lamp to cool before han-

dling.

• 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 after 1600

hours (up to 2100 hours : Eco mode) of service. If this happens,

be sure to replace the lamp. If you continue to use the lamp after

1500 hours (up to 2000 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 replacement.

To replace the lamp:

1. Loosen the lamp cover screw until the screwdriver goes into a free-

wheeling condition and remove the lamp cover. The lamp cover screw

is not removable.

Interlock

2. Loosen the two screws securing the lamp housing until the screw-

driver goes into a freewheeling condition. The two screws are not

removable.

3. 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 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 replacement lamp

(LT60LP).

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 1600 hours (up to

2100 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.
