NOTE
THE LAMP (continued)
Replacing the lamp
All projector lamps will wear out eventually. If used for long periods of time, the image could become
darkened, and the color contrast could be impacted as well. We recommend that you replace your lamps
early. If the LAMP indicator turns red, or a message prompts you to replace the lamp when you power up
the projector, the lamp needs to be replaced. (See "Related Messages" ( ) and "Regarding the
Indicator Lamps" ( ) for details.)
1
Turn off the projector, and unplug the
power cord. Allow the lamp bulb to cool
for at least 45 minutes, and prepare a
new lamp.
4
Insert the new lamp, and
tighten the 3 screws firmly to
lock it in place.
5
Interlocking the 2 tabs of the
lamp cover to the projector,
put the lamp cover on the
projector.
Then push the point of the
lamp cover to fix it, as shown
in the figure.
Make sure that the lamp
cover doesn’t come up.
2
After making sure that the projector has
cooled adequately, slide the knob of a
lamp cover lock as shown in the figure.
Then, one side of the lamp cover is
raised. Pull up the lamp cover and
remove it, as shown in the figure.
3
Unscrew the 3 screws, and slowly pull
out the lamp by the handle.
• Be careful not to touch the inside of the lamp case.
ATTENTION • Make sure that the screws are screwed in firmly. Loose screws could result in damage or injury.
• Do not use with lamp cover removed.
• Do not reset the lamp timer without replacing the lamp. Reset the lamp timer always when replacing
the lamp. The message functions will not operate properly if the lamp timer is not reset correctly.
• When the lamp has been replaced after the message of “CHANGE THE LAMP .....THE POWER
WILL TURN OFF AFTER 0 hr.” is displayed, or the LAMP indicator is red, complete the following
operation within 10 minutes of switching power on.
6
Turn on the projector power,
and reset the lamp timer.
