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.
1Switch the projector OFF, remove the power cord from the power outlet, and wait at least 45 minutes for the unit to cool.
2Prepare a new lamp.
3Check that the projector has cooled sufficiently, and gently
turn it upside down.
4 Loosen the two screws as shown in the diagram, and remove the lamp cover.
5 Loosen the one screw, and gently remove the lamp while holding the grips. Touching the inside of the lamp case may result in uneven coloring.
6Install the new lamp and tighten the one screw firmly. Make sure that the lamp assembly is seated properly before replacing the other screw.
7Replace the lamp cover in position and tighten the two
screws firmly.
8 Gently turn the projector
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.
