Lamp Replacement

Caution
To reduce the risk of electrical shock, always turn off the projector and dis-
connect the power cord before changing the lamp.
1. Press the POWER button to switch off the
projector. Disconnect the power cord from
the outlet and the projector.
2. Loosen the screw and remove the lamp
cover. If the lamp is hot, avoid burns by
waiting 45 minutes until the lamp has cooled.
3. Loosen the 3 screws. (It is strongly
recommended you use a magnetic-headed
screwdriver.) Pull the handle to remove the lamp
housing. If the screws are not loosened completely,
they could injure your fingers. Do not insert your
hand into the box after the lamp is removed. If you
touch the optical parts inside, this could cause
color unevenness.
4. Replace the lamp with a new one. Insert it into
the projector, and tighten the screws firmly.
Loose screws may cause a bad connection, which
may result in malfunction.
5. Re-install the lamp cover and tighten the screw.
Do not turn on the power with the lamp
cover removed. Whenever the lamp is
replaced, reset the total lamp operation time. Do
not reset if the lamp is not replaced as this
could cause breakage.
