WARNING:

- Allow a projector to cool, for at least 45 minutes before you open Lamp

Cover. The inside of a projector can become very hot.

- For continued safety, replace with a lamp assembly of the same type.

- Do not drop a lamp assembly or touch a glass bulb! The glass can

shatter and may cause injury.

Procedure

1Turn off the projector and disconnect the AC plug. Allow the projector to

cool at least for 45 minutes.

2Remove 1 screw and remove the lamp cover.

3Loosen 2 screws and pull out the lamp assembly by grasping the handle.

4Replace the lamp assembly securely and tighten 2 screws.

5Close the lamp cover and tighten 1 screw.

6Connect the AC Power Cord to the projector and turn on the projector.

Note:

- Do not reset the Lamp Replace Counter, except after lamp is replaced.

- The projector can not be turned-on with lamp cover removed, because

when the lamp cover is removed, the lamp cover switch is also released

to switch off the mains power for safety.

7Reset the Lamp Replace Counter, see below explanation.

■Lamp Replacement

1Turn the projector on, and press the MENU button

and the on-screen menu will appear. Press the

POINT LEFT/RIGHT buttons to move the red frame

pointer to the Setting Menu icon.

2Press the POINT DOWN button to move the red

frame pointer to “Lamp counter reset” and then press

the SELECT button. The message “Lamp replace

counter reset?” is displayed. Move the pointer to [Yes]

and then press the SELECT button.

3Another confirmation dialog box appears and select

[Yes] to reset Lamp Replace Counter .

Please refer to the owners manual for further informa-

tion.

Recommendation

Should the air filter become clogged with dust particles,

it will reduce the cooling fan’s effectiveness and may

result in internal heat build up and short lamp life. We

recommend cleaning the air filter after the projection

lamp is replaced.

Refer to “Air Filter Cleaning”.

The LAMP REPLACE indicator will light yellow when

the total lamp used time reaches 2500 hours. This is

to indicate that lamp replacement is required.

The total lamp used time is calculated by using the

below expression;

Total lamp used time = Teco + Tnormal(1+1/4)

Teco :used time in the Eco mode

Tnormal :used time in the Normal and Auto mode

You can check the lamp replace counter following to

below procedure.

1Press and hold the POWER ON-OFF button on the

projector or the remote control unit for more than 20

seconds.

2 The projector used time and lamp used time will be

displayed on the screen briefly.
