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 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.
