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 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.
