Maintenance
Lamp 
To order a new lamp unit see page 26 for contact information and see Table 15 for part numbers. The 
estimated lamp life is 2000 hours. Before replacing the lamp, turn the Power Switch OFF, remove 
the power cord from the power outlet, and wait approximately 45 minutes until the lamp has cooled. 
CAUTION: 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 10: OSD Messages on page 21 and Table 
11: Indicator Messages on page 21.
NOTE: The LAMP indicator is also red when the lamp unit reaches high temperature. Before 
replacing the lamp switch the POWER OFF, wait approximately 20 minutes, and switch the 
POWER ON again. If the LAMP indicator is still red replace the lamp.

     WARNINGS
• Dispose of the used lamp according to local regulations.
• Since the lamp is made of glass, do not drop the unit and do not scratch 
the glass.
• Do not reuse the old lamp. This could cause the lamp to explode.
• If it is probable that the lamp has exploded (you have heard an explosive 
sound), disconnect the power plug from the power outlet and ask your 
dealer to replace the lamp. The lamp is protected by a cover glass, but in 
rare cases the reflector and the inside of the projector could be damaged 
by broken or shattered glass. Broken pieces of glass could cause injury.
• Do not use the projector with the lamp’s front glass covering removed.

Replacing the Lamp
When the indicator shows that there is zero (0) hours of lamp life remaining, the unit will 
automatically shut off within 10 minutes. If you see this message you should replace the lamp. 
However, you may replace the lamp anytime after the first warning message appears at 
approximately 300 hours of remaining lamp life.   
Resetting the Lamp Timer
After replacing the lamp, it is important that you reset the lamp timer. When the lamp has been 
replaced after the THE POWER WILL TURN OFF AFTER 0hr. message is displayed, complete 
the following steps within 10 minutes of switching power ON. The power will be turned off 
automatically after 10 minutes.

Image.
3Press the RESET button and hold for approximately 3 seconds. The DEFAULT and CANCEL 
options will display.
4Press the Up arrow button to select the DEFAULT. The remaining lamp life is now reset to 2000 
hours. 
IMPORTANT: Do not reset the lamp timer without replacing the lamp. The message functions will 
not operate properly if the lamp timer is not reset correctly.
1Switch the projector OFF, remove the power cord from the 
power outlet, and wait at least 45 minutes for the unit to 
cool.

replacing the other screw.
7Replace the lamp cover in position and tighten the two 
screws firmly.
8Gently turn the projector right-side up.
