Maintenance, If something abnormal happens

Warnings and precautions

Maintenance

∗Be sure to unplug the USB cable before cleaning the equipment.

Clean the inside of the equipment once a year.

•The equipment is of semi-sealed construction, so dust may eventually accumulate inside. This may cause poor operation due to a reduction in the level of infrared light available for touch detection. Cleaning frequency will vary depending on the setup location; if in doubt consult the dealer from whom you purchased the equipment.

•Be careful not to touch the infrared transmissive area on the screen of the plasma display and rub the screen with excessive force.

Cleaning of the infrared transmissive area

•Once a day, use a soft cloth to wipe off any soiling or debris on the infrared transmissive area. Failure to do so will cause a malfunction, but on such an occurrence you can restore normal function simply by gently wiping the soiling off. If soiling is severe, wet a cloth in household detergent diluted in water, wring well, wipe off the soiled part, and then wipe well with a dry cloth.

•Be aware that if you apply volatile fluids such as thinner, benzene or insecticide, or allow long-term contact with products containing materials such as rubber or vinyl, the surface of the equipment may discolor or deform. Also, be careful of wiping with chemically-treated cloths, because such action may cause similar to happen.

If something abnormal happens

If the equipment starts to smoke or emit a strange odor

•It is extremely dangerous to continue using the equipment in such a malfunctioning state.

Immediately unplug the USB cable from the computer, and request repair from the dealer from whom you purchased the equipment.
