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 mag-
netic-head screwdriver.) Pull the
handle to remove the lamp housing.
If the screws are not loosened com-
pletely, they could injure your fin-
gers. 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 opera-
tion time. Do not reset if the lamp is
not replaced as this could cause
damage.
