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.

28

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.

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.

Cleaning and replacing the dust filters (Optional accessory)

Cleaning the dust filters

Clean the dust filters after every 1000 hours of use. If they are note cleaned
periodically, they can become clogged with dust, preventing proper ventilation. This
can cause overheating and damage the projector.

Follow these steps:

1. Turn the projector off. Wait for the Power LED to stop flashing then unplug the

power cord.

2. Allow the projector at least 30 mins to cool down.
