CAUTION
• Potential hazard of glass particles if lamp ruptures. In case of lamp rupture, contact your nearest
Sharp Authorized LCD Projector Dealer or Service Center for a replacement.
• Do not remove the lamp cage directly after operation of the projector. The lamp may be extremely
hot. Wait at least one hour after the power cord is disconnected to allow the surface of the lamp cage
to fully cool before removing the lamp cage.
Caution Concerning the Lamp
• This projector utilizes a pressurized mercury lamp. A loud sound may indicate lamp failure. Lamp failure can
be attributed to numerous sources such as excessive shock, improper cooling, surface scratches or deterioration
of the lamp due to a lapse of usage time. The period of time up to failure largely varies depending on the
individual lamp and/or the condition and the frequency of use. It is important to note  that failure can often result
in the bulb cracking.
• When the LAMP REPLACEMENT indicator and on-screen display icon is illuminated or blinks, it is recommended
that the lamp be replaced with a new one immediately, even if the lamp appears to be operating normally.
• Should the lamp break, the glass particles may spread inside the lamp cage or gas contained in the lamp may
be vented into the room from the exhaust vent. Because the gas in this lamp includes mercury, ventilate the
room well if the lamp breaks and avoid all exposure to the released gas. In case of exposure to  the gas, consult
with a doctor as soon as possible.
• Should the lamp break, there is also a possibility that glass particles may spread inside of the projector. In such
a case, it is recommended you contact your nearest Sharp Authorized LCD Projector Dealer or Service Center
to remove the damaged lamp and assure safe operation.
