Maintenance
The projector needs proper maintenance. You should keep the lens clean as dust, dirt 
or spots will project on the screen and diminish image quality. If any other parts need 
replacing, contact your dealer or qualified service personnel. When cleaning any part 
of the projector, always switch off and unplug the projector first.
Warning
• Never open any of the covers on the projector. Dangerous electrical voltages inside the 
projector can cause severe injury. Do not attempt to service this product yourself. Refer 
all servicing to qualified service personnel.
Cleaning the lens
Gently wipe the lens with lens cleaning paper. Do not touch the lens with your hands.
Cleaning the projector housing
Gently wipe with a soft cloth. If dirt and stains are not easily removed, use a soft cloth 
damped with water, or water and neutral detergent, and wipe dry with a soft, dry cloth.
Note
• Turn off the projector and remove the AC power cord from the power outlet before 
beginning maintenance work.
• Make sure the lens is cool before cleaning.
• Do not use detergents or chemicals other than those noted above. Do not use benzene 
or thinners.
• Do not use chemical sprays.
• Use a soft cloth or lens paper only.

Replacing the Lamp
As the projector operates over time, the brightness of the projector lamp gradually 
decreases and the lamp becomes more susceptible to breakage. We recommend 
replacing the lamp if a warning message is displayed. Do not attempt to replace the 
lamp yourself. Contact the qualified service personnel for replacement.
Note
• The lamp is extremely hot right after turning off the projector. If you touch the lamp, you 
may scald your finger. When you replace the lamp, wait for at least 45 minutes for the 
lamp to cool down.
• Do not touch the lamp glass at any time. The lamp may explode due to improper 
handling, including the touching of the lamp glass.
• Lamp lifetime may differ from lamp to lamp and according to the environment of use. 
There is no guarantee of the same lifetime for each lamp. Some lamps may fail or 
terminate their lifetime in a shorter period of time than other similar lamps.
• A lamp may explode as a result of vibration, shock or degradation as a result of hours of 
use as its lifetime draws to an end. Risk of explosion may differ according to the 
environment or conditions in which the projector and lamp are being used.
• Wear protective gloves and eyeglasses when fixing or detaching the lamp.
• Faster on-off-cycles will damage the lamp and reduce lamp life. Wait at least for 5 
minutes to turn off the projector after powering on.
• Do not operate the lamp in proximity to paper, cloth, or other combustible material nor 
cover it with such materials.
• Do not operate the lamp in an atmosphere containing an inflammable substance, such 
as thinner.
• Thoroughly ventilate the area or the room when operating the lamp in an oxygen 
atmosphere (in the air). If ozone is inhaled, it could cause headaches, nausea, dizziness, 
and other symptoms.
• The inorganic mercury is involved in the lamp. If the lamp bursts, the mercury inside the 
lamp will be exposed. Leave the area immediately if the lamp shatters while being 
operated and ventilate the area for at least 30 minutes in order to avoid the inhalation of 
mercury fumes. Otherwise it could be harmful to user’s health. 
						

							37 1. Turn off the projector.

9. Reset the lamp hour. Refer to the “Option > Lamp Setting” menu.
Note
• Dispose the used lamp according to local regulations.
• Ensure that screws are tightened properly. Screws not tightened fully may result in 
injury or accidents.
• Since the lamp is made of glass, do not drop the unit and do not scratch the glass.
• Do not reuse the old lamp. This could cause the lamp to explode.
• Be sure to turn off the projector and unplug the AC power cord before replacing the 
lamp.
• Do not use the projector with the lamp cover removed.

Troubleshooting
Refer to the symptoms and measures listed below before sending the projector for 
repairs. If the problem persists, contact your local reseller or service center. Please 
refer to "LED Indicator Messages" as well.
Start-up problems
If no lights turn on:
•
Be sure that the power cord is securely connected to the projector and the other end is 
plugged into an outlet with power.
• Press the power button again.
•
Unplug the power cord and wait for a short while, then plug it in and press the power
button again.
Image problems
If the searching source is displayed:
•
Press SOURCE on the projector or Source on the remote control to select an active 
input source.
• Be sure the external source is turned on and connected.
•
For a computer connection, ensure your notebook computer’s external video port is
turned on. Refer to the computer manual.
If the image is out of focus:
•
While displaying the on-screen menu, adjust the focus ring. (The image size should
not change; if it does, you are adjusting the zoom, not the focus.)
• Check the projection lens to see if it needs cleaning.
• If the image is flickering or unstable for a computer connection:
• Press 
MENU on the projector or Menu on the remote control, go to Video/Audio and
adjust Frequency or Tracking.
Remote control problems
If the remote control does not operate:
• Be sure nothing is blocking the remote control receiver on the front of the projector. 
Use the remote control within the effective range.
• Aim the remote control at the screen or at the front of the projector.
•
Move the remote control so it is more directly in front of the projector and not as far to 
the side.
