9Maintenance

To clean the LCD panel, wipe off water droplets or oil immediately with absorbent cotton or a soft lint-free cloth. Staining and discoloration may occur if a liquid is left on the panel for long periods. If the surface (polarizer) of the LCD panel is dirty or stained, use absorbent cotton or a soft lint-free cloth to remove the residue as follows:

1.Turn off the display and disconnect it from the power supply.

2.Do not spray any liquid directly on the screen. Dampen a clean, soft, lint-free cloth with water only (using a paper towel or dirty cloth can scratch the screen).

3.Gently wipe the screen starting from the top of the screen to bottom wiping in a downward motion. Be careful not to press too hard to avoid damaging the screen.

4.To avoid streaking, wipe the screen again with another clean, dry, lint-free cloth.

NOTICE!

If water does not work, use a mild cleaner labeled for use with LCD panels, available at office supply stores.

Do not use any of the following as a cleaning agent:

–Ketone type materials

–Ethyl alcohol

–Ethyl acid

–Toluene

–Methyl chloride

–Ammonia

Use of these materials may permanently damage the polarizer due to a chemical reaction.
