Step 1. Turn off the projector. Discon-
nect the power cord from the
outlet and the projector.
Step 2. Loosen the screw and remove the
lamp cover. If the lamp is hot,
avoid burns by waiting 45 min-
utes until the lamp has cooled.
Step 3. Loosen the 3 screws. (It is
strongly recommended that you
use a magnetic-head screw-
driver.) Pull the handle to
remove the lamp housing. If the
screws are not loosened com-
pletely, they could injure your
fingers. Do not insert your hand
into the box after the lamp is
removed. If you touch the opti-
cal components inside, this
could cause color unevenness in
projected images.

Step 4. Replace the lamp with a new one.
Insert it into the projector, and
tighten the screws firmly. Loose
screws may cause a bad connec-
tion, which may result in mal-
function.
Step 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.
