Precautions for use
Cleaning and maintenance
The front of the liquid crystal panel has been specially treated. Wipe the surface of the liquid crystal panel
gently using only a cleaning cloth or a soft, lint-free cloth.
•
If the surface is particularly dirty, wipe with a soft, lint-free cloth which has been soaked in pure water or water in
which neutral detergent has been diluted 100 times, and then wipe it evenly with a dry cloth of the same type until
the surface is dry.
Wipe off dirt on the IR transmission part with soft cloth.
•
Wipe off dirt on the IR transmission part with soft cloth once a day.
If malfunction is due to dirt on the IR transmission part, simply wiping it off lightly can recover the performance.
If dirt is sticky, wipe it off with cloth wrung out of neutral detergent diluted with water and then wipe the part with
dry cloth.
•
If the substance such as the material of the supplied pen is stuck on the glass surface, wipe it with a wet cloth.
Note that if a deep scratch is caused by using objects other than the supplied pen, it may not be wiped off.
•
Do not scratch or hit the surface of the panel with fingernails or other hard objects, otherwise the surface may
become damaged. Furthermore, avoid contact with volatile substances such as insect sprays, solvents and
thinner, otherwise the quality of the surface may be adversely affected.
If the cabinet becomes dirty, wipe it with a soft, dry cloth.
•
If the cabinet is particularly dirty, soak the cloth in water to which a small amount of neutral detergent has been
added and then wring the cloth dry. Use this cloth to wipe the cabinet, and then wipe it dry with a dry cloth.
•
Do not allow any detergent to come into direct contact with the surface of the Display. If water droplets get inside
the unit, operating problems may result.
•
Avoid contact with volatile substances such as insect sprays, solvents and thinner, otherwise the quality of the
cabinet surface may be adversely affected or the coating may peel off. Furthermore, do not leave it for long
periods in contact with articles made from rubber or PVC.
Usage of a chemical cloth
•
Do not use a chemical cloth for the panel surface.
•
Follow the instructions for the chemical cloth to use it for the cabinet.
Touch panel
Carefully observe the following instructions as the display has an optical touch panel.
Do not expose the display to direct sunlight or strong light source during use.
•
Otherwise malfunction may occur since the optical touch panel of the display uses infrared rays.
After turning on the power of the display, do not touch the IR transmission part and
the screen until any image is displayed.
•
Otherwise the touched part may be detected as defective elements, resulting in
abnormal operation. If this occurred, turn the display off and then on.
Always use a finger or the supplied pen to operate the touch panel. Do not use a hard or sharp tip such as
nail, ball-point pen, and pencil.
When using any other infrared device, keep a distance to prevent erroneous operation.
