MAINTENANCE MAINTENANCE
Lamp
HIGH VOLTAGE
HIGH TEMPERATURE
HIGH PRESSURE
Contact your dealer before replacing the lamp.
For the optional lamp, see the item “Option Parts” of the Table 12.
Before replacing the lamp, switch power OFF, remove the power cord from the power outlet, and
wait approximately 45 minutes until the lamp has cooled. The lamp may explode if handled at high
temperatures.
Lamp Life
Projector lamps have a finite life. The image will become darker, and hues will become weaker,
after a lamp has been used for a long period of time. 
Replace the lamp if the LAMP indicator is red, or the CHANGE THE LAMP message appears
when the projector is switched ON. See Table 9 of P.20 and Table 10 of P.21.
•The LAMP indicator is also red when the lamp unit reaches high temperature. Before
replacing the lamp, switch power OFF, wait approximately 20 minutes, and switch power ON again.
If the LAMP indicator is still red, replace the lamp.NOTE
WARNINGAmercury lamp used in this LCD projector is made of glass and has high
internal pressure.  The mercury lamp can burst with a big noise due to deterioration
resulting from a shock, crack and passage of time, and can end its service life in unlit
condition.  Lamps also have a considerably different service life and can sometimes end up
in burst or turn to unlit condition soon after use.  Furthermore, when the lamp is blown up,
glass fragments can get scattered around the lamp house and some gas containing mercury
inside the lamp can leak out of the projector’s air vent.
• Handle the lamp with utmost care as it can burst during use if subjected to a shock or
impact or if scratched or cracked.
• Probability for the burst will increase if the lamp is used for extended period of time or
used exceeding the period of replacement.  You are advised to follow instructions for lamp
replacement as soon as they are given (Refer to Table 9 of Page 20, Table 10 of Page 21).
Avoid any reuse of an old lamp (used lamp) since such reuse can result in burst.
• In case the lamp gets blown up in a short period of time after use, some electrical failures
or troubles other than the lamp itself may be suspected as causes.  Under such
circumstances, consult the store where you purchased it or a service company.
• Should the lamp burst (accompanied by a big bursting noise), perform ventilation
sufficiently, and exercise maximum caution not to inhale any gas out of the projector’s air
vent or not to let it enter your eyes or mouth.
• Should the lamp burst (accompanied by a big bursting noise), make absolutely sure to
unplug the power cord from the outlet and ask the store where you bought the lamp for
immediate replacement.  You should not engage in cleanup or replacement of the lamp by
yourself since scattered glass fragments can damage the inside of projector or can result in
personal injury when you handle it. 
• When you dispose of any used lamps, be sure to observe and follow local ordinances and
regulations of the area or district where they are subjected to disposal.  Generally speaking,
the lamps are treated similarly as glasses and bottles in most cases, but there are areas or
districts where lamps are classified as a separate collection, and so be sure to use caution. 
• Never use the lamp in a state where the lamp cover is removed.

Replacing the Lamp
1. Switch the projector OFF, remove the power cord from the
power outlet, and wait at least 45 minutes for the unit to cool.
2. Prepare a new lamp.
3. Check that the projector has cooled sufficiently, and gently
turn it upside down.
4. Loosen the screw as shown in the diagram, and remove the
lamp cover.
5. Loosen the two screws, and gently remove the lamp while

6. Install the new lamp and tighten the two screws firmly. Also
steadily push the opposite side of the screwed lamp into the
unit.
7. Replace the lamp cover in position and tighten the screw
firmly.
8. Gently turn the projector right-side up.
Resetting the Lamp Timer
Reset the lamp timer after replacing the lamp. When the lamp has been replaced after the LAMP
indicator is red, or the CHANGE THE LAMP message is displayed, complete the following
operation within ten minutes of switching power ON. The power will be turned off automatically in
over 10 minutes.
1. Switch power ON, and press the RESET button, for approximately three seconds. The ‘LAMP
xxxx hr’ message will appear on the lamp timer on the bottom of the screen.
2. Press the MENU button on the remote control transmitter, or the RESET button on the control
panel, while the lamp timer is displayed. The ‘LAMP xxxx 
→0 CANCEL’ message will
then appear.
3. Press the  and select 0, and wait until the timer display is cleared.
•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.NOTE
CAUTION• Ensure that screws are tightened
properly. Screws not tightened fully may result
in injury or accidents.
• Do not use the projector with the lamp cover
removed.
