10 Maintenance
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 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 computer or display.
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.
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.

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