Hg LAMP CONTAINS MERCURY For State Lamp Disposal Information
www.lamprecycle.org or 1-800-BE-SHARP
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 indicator and on-screen display icon are illuminated or flash, 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 Projector
Dealer or Service Center to remove the damaged lamp and assure safe operation.
Replacing the Lamp
Caution
• Do not remove the lamp unit immediately after operation of the projector. The lamp will be hot and touching
it can lead to burn or injury.
• Wait at least one hour after the power cord is disconnected to allow the surface of the lamp unit to fully cool
before removing the lamp unit.
■ Carefully change the lamp by following the instructions described in this section. *If you wish, you
may have the lamp replaced at your nearest Sharp Authorized Projector Dealer or Service Center.
* If the new lamp does not illuminate after replacement, take your projector to the nearest Sharp Authorized
Projector Dealer or Service Center for repair.
