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. Turn 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 that you use a
magnetic-head 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 components
inside, this could cause color
unevenness in projected images.
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 damage.
