9. Maintenance

This chapter describes the simple maintenance procedures you should follow to replace the lamp and the filter, and to clean the filter and the cabinet.

z Replacing the Lamp

The projector has two lamps. The lamp replacement procedure applies to both lamps. After your lamp 1 and 2 has been operat- ing for 2000 hours (Normal mode on the standard life lamp) 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 as soon as possible to maintain optimal projector performance.

NOTE: Be sure to use the same lamp type for both lamp 1 and 2.

CAUTION

•DO NOT TOUCH THE LAMP immediately after it has been used. It will be extremely hot. Turn the projector off, wait 90 seconds (2 minutes in the optional extended life lamp GT60LPS), turn off the main power switch, 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 the two lamp case screws. You could receive an electrical shock.

•The projector will turn off and go into stand by mode after 2100 hours (Normal mode on the standard life lamp) of service. If this happens, be sure to replace the lamp. If you continue to use the lamp after 2000 hours (Normal mode on the standard life lamp) 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 hap- pens, contact your NEC dealer for lamp replacement.

•When "Dual" is selected in "Lamp Select" of "Lamp Settings", replace both lamp 1 and 2 at the same time so that the projected image will keep an even color temperature.

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

(Standard life lamp: GT60LP or Extended life lamp: GT60LPS).

4.Secure it in place with the two screws. Be sure to tighten the screws.

5. Reattach the lamp cover.

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.

6. Tighten the lamp cover screw. Be sure to tighten the screw.

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 on the handle.

Interlock

NOTE: There is an interlock on this case to prevent the risk of electrical shock. Do not attempt to circumvent this interlock.

NOTE: Replacing a new lamp automatically clears the lamp usage hours.

NOTE: The lamp housing has an EEPROM chip memorizing its amount of usage hours. You can check the amount usage hours in Information of the menu. (The standard lamp and the optional lamp have an EEPROM chip in it so that when you remove it, your lamp usage hours are saved in its own memory. The projector reads the lamp usage hours from the EEPROM chip to display them in Information of the menu.)
