sufciently. The care in a high temperature state of the projector could cause a burn and/or
malfunction to the projector.
Avoid wetting the projector or inserting liquids in the projector. It could result in a re, an electric
shock, and/or malfunction to the projector.
• Don’t put a container containing water, cleaner or chemicals near the projector.
• Don’t use aerosols or sprays.
CAUTION
Please take right care of the projector according to the following. Incorrect care could cause not
only an injury but adverse inuence such as discoloration, peeling paint, etc.
• Do not use cleaner or chemicals other than those listed below.
• Do not polish or wipe with hard objects.
Inside of the projector
In order to ensure the safe use of the projector, it needs to clean and inspect the projector about
once a year.
Caring for the lens
If the lens is awed, soiled or fogged, it could cause deterioration of display quality. Please take
care of the lens, being cautions of the handling.
1. Turn the projector off, and unplug the power cord. Allow the projector to cool sufciently.
2. After making sure that the projector is cool adequately, lightly wipe the lens with a commercially
available lens-cleaning wipe. Do not touch the lens directly with your hand.
• Use commercially available lens tissue to clean the lens (used to clean cameras, eyeglasses, etc.).
• If the lens is heavily soiled, wipe it with a cloth moistened with little water.
• Never use polishing agents, detergents, chemicals, or solvents such as benzine or thinner.
• Excepting for lens, use a soft cloth to clean. When excessively soiled, dilute a neutral detergent in
water, wet and wring out the soft cloth.
Caring for the cabinet and remote control
Incorrect care could have adverse inuence such as discoloration, peeling paint, etc.
1. Turn the projector off, and unplug the power cord. Allow the projector to cool sufciently.
2. After making sure that the projector is cool adequately, lightly wipe with gauze or a soft cloth. If

5-1 Notice of AUTO adjustment
Use of AUTO adjustment with the image through analog RGB input optimizes V_POSI, H_POSI,
and H_PHASE automatically.
In case that display image has dark tone around its peripheral, AUTO operation sometimes makes
artifacts in the image, shifts capture area and so on. Those failures are caused by period of image
data is not exactly distinguished to period of blanking on signal processing.
To avoid such phenomena, AUTO function should be used with the full size picture that has bright
tone on its peripheral.
NOTE:
• The phenomenon of the failure ofAUTO adjustment depends on resolution of input source, scene
of picture etc.
• There is no above failure ofAUTO with video source through VIDEO port. The reason is
recognition of input signal’s standard does not need to search the capture range from input signal
itself.
Image when AUTO operates correctly Image when AUTO fails.
• Noting image of top or bottom lines.
• Shift of the image to East or West.
• Artifacts on image. Etc.
