Maintenance

Step 1. Turn the projector off. 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, you could injure your
fingers. Do not insert your hand
into the projector after the lamp
is removed. If you touch the
optical components inside, this
could cause color unevenness in
projected images.

Step 4. Replace the lamp with the new

one. Insert it into the projector,
and tighten the screws firmly.
Loose screws may cause a bad
connection, which may result in
malfunction.

Step 5. Re-install the lamp cover and

tighten the screw. Do not turn
the power on 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.
