Maintenance
Cleaning the projector
Ensure that you have unplugged the power 
cord before cleaning the projector.
The cabinet as well as the operation panel is 
made of plastic. Avoid using benzene or 
thinner, as these can damage the  nish on 
the cabinet.
Do not use volatile agents such as 
insecticides on the projector.
Do not attach rubber or plastic items to the 
projector for long periods.
The effects of some of the agents in the 
plastic may cause damage to the quality or 
 nish of the projector.
Wipe off dirt gently with a soft  annel cloth.
Using a chemical cloth (wet/dry sheet type 
cloth, etc.) may deform the components of 
the cabinet or cause cracking.
Wiping with a hard cloth or using strong 
force may scratch the cabinet surface.
When the dirt is hard to remove, soak a cloth 
in a mild detergent diluted with water, wring 
the cloth well and then wipe the projector.
Strong cleaning detergents may discolor, 
warp or damage the coating on the projector. 
Make sure to test on a small, inconspicuous 
area on the projector before use.

■Cleaning the lens
Use a commercially available blower or lens 
cleaning paper (for glasses and camera 
lenses) for cleaning the lens. Do not use any 
liquid type cleaning agents, as they may 
wear off the coating  lm on the surface of the 
lens.
As the surface of the lens can easily get 
damaged, be careful not to scrape or hit the 
lens.
Cleaning the exhaust and intake vents
Use a vacuum cleaner to clean dust from the 
exhaust vent and the intake vent.
Info
If you want to clean the air vents during 
projector operation, ensure you press 
STANDBY/ON on the projector or 
STANDBY on the remote control and put the 
projector into Standby mode. After the 
cooling fan has stopped, clean the vents.

Maintenance Indicators
The warning lights (power indicator, lamp indicator and temperature warning indicator) on the 
projector indicate problems inside the projector.
If a problem occurs, either the temperature warning indicator or the lamp indicator will 
illuminate red, and the projector will enter Standby mode. After the projector has entered 
Standby mode, follow the procedures given below.
To p  V i e wLamp indicator Temperature warning indicator
Power indicator
About the temperature warning indicator
If the temperature inside the projector increases, due to blockage of the air vents, or the setting 
location, the temperature warning indicator will blink. And if the temperature keeps on rising, 
“
” will illuminate in the lower left corner of the picture with the temperature warning 
indicator blinking. If this state continues, the lamp will turn off, the cooling fan will run and then 
the projector will enter Standby mode. When you  nd the temperature warning indicator 
blinking, be sure to perform the measures described on page 
59.
About the lamp indicator
When the remaining lamp life becomes 5% or less,  (yellow) and “Change The Lamp” will 
be displayed on the screen. When the percentage becomes 0%, it will change to  (red), the 
lamp will automatically turn off and then the projector will automatically enter Standby mode. 
At this time, the lamp indicator will illuminate in red.
If you tr y to turn on the projector a fourth time without replacing the lamp, the 
projector will not turn on. ■

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

Regarding the Lamp
Lamp
It is recommended that the lamp (sold separately) be replaced when the remaining lamp life becomes 
5% or less, or when you notice a signi cant deterioration in the picture and color quality. The lamp life 
(percentage) can be checked with the on-screen display. (See page 
53.)
Purchase a replacement lamp of type AN-D350LP from your place of purchase, nearest Sharp 
Authorized Projector Dealer or Service Center.
IMPORTANT NOTE TO U.S. CUSTOMERS:
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, 
please call toll-free: 1-888-GO-SHARP (1-888-467-4277). 
Hg  LAMP  CONTAINS  MERCURY  For  State  Lamp  Disposal          
Information
www.lamprecycle.org or 1-800-BE-SHARP 
                     U.S.A ONLY
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 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.
Replacing the Lamp
Caution
Do not remove the lamp unit from the projector right after use. The lamp will be very hot and may cause 
burns 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 Ser vice Center.
*  If the new lamp does not light after replacement, take your projector to the nearest Sharp Authorized Projector 
Dealer or Ser vice Center for repair.

Optimum image quality will be achieved by matching your computers output resolution to the 
resolution that corresponds to “TRUE” in the “Display” column shown above.
When “Screen resolution” of the computer is different from the resolution displayed on the projected 
image, follow the procedures shown below.
– Refer to “Resolution” on the “SIG-ADJ” menu and select the same resolution as the resolution in 
“Screen resolution” of the computer.
– 
Depending on the computer you are using, the output signal may not be faithful to the “Screen resolution” 
adjustment. Check the settings of the computers signal output. If the settings cannot be changed, it is 
recommended that the resolution be set to the one that corresponds to “TRUE” in the “Display” column.
