• If the temperature warning indicator illuminates, and the projector enters standby mode, follow the

possible solutions above and then wait until the projector has cooled down completely before plug-
ging in the power cord and turning the power back on. (At least 10 minutes.)

• If the power is turned off for a brief moment due to power outage or some other cause while using

the projector, and the power supply recovers immediately after that, the lamp indicator will illumi-
nate in red and the lamp may not be lit. In this case, unplug the power cord from the AC outlet,
replace the power cord in the AC outlet and then turn the power on again.

• The cooling fan keeps the internal temperature of the projector constant and this function is con-

trolled automatically. The sound of the cooling fan may change during operation because the fan
speed may change and this is not a malfunction.

• Do not unplug the power cord after the projector has entered standby mode and while the cooling

fan is running. The cooling fan runs for about 90 seconds.

■ It is recommended that the lamp (sold separately) be replaced when the remaining lamp life becomes

5% or less, or when you notice a significant deterioration in the picture and color quality. The lamp life
(percentage) can be checked with the on-screen display. (see page 

■ Purchase a replacement lamp of type AN-XR20LP from your place of purchase, nearest Sharp

Authorized Projector Dealer or Service Center.

■ 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 are illuminated, 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, 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 assure safe operation.

■ 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 a doctor as soon as possible.

• Do not remove the lamp unit from the projector right after use. The lamp will be very hot and may

cause burn or injury.

■ Carefully change the lamp by following the instructions described in this section. * If you wish,

* If the new lamp does not light after replacement, take your projector to the nearest Sharp Authorized

Projector Dealer or Service Center for repair.

The lamp included with this projector is backed by a 90-day parts and labor limited
warranty. All service of this projector under warranty, including lamp replacement,
must be obtained through a Sharp Authorized Projector Dealer or Service Center.
For the name of the nearest Sharp Authorized Projector Dealer or Service Center,
