Maintenance

The front of the display panel has been specially treated. Wipe the panel surface 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.
• Do not scratch or hit the surface of the panel with ¿ ngernails 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.

Display is dropped, or if the cabinet becomes damaged,
disconnect the power cord plug immediately.
