9 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 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.
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.
