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.
