To reduce the risk of electrical shock, always turn off projector and disconnect
power cord before changing lamp.
• To reduce the risk of severe burns, allow the projector to cool for at least 45 minutes
before replacing the lamp.
• To reduce the risk of cuts to fingers and damage to internal components, use caution when
removing lamp glass that has failed and shattered into sharp pieces.

• To reduce the risk of cuts to fingers and/or decreasing image quality by touching the
lens, do not insert hand into the empty lamp compartment when the lamp has been
removed.

of this lamp in a proper manner.
1. Turn the main power switch off and disconnect the power cord from the outlet.
2. Loosen screw and remove the lamp cover. If the lamp is hot, avoid burns by waiting 45 minutes
until lamp has cooled.
3. Loosen two screws designated by arrows below. (It is strongly recommended to use a magnetic-
headed screwdriver, if possible. Pull the handle to remove lamp housing. If the screws are not
loosened completely, they could damage your fingers. Do not insert your hand into the box after the
lamp is removed. If the optical parts inside are touched by hand, it could cause color unevenness, etc.
4. Replace the lamp with the new one, insert into projector, and tighten the screws. Firmly tighten
the lamp screws. Loose screws may cause a bad connection, which may result in a malfunction.

Whenever the lamp has been replaced, reset the total operation time of the lamp. Do not reset if the
lamp was not replaced, as this could cause breakage.
