Caring for your monitor

Be sure to turn off the power before you perform any maintenance on the monitor.
Do not:
· Apply water or liquid directly to your monitor.
· Use solvents or abrasives.
· Use flammable cleaning materials to clean your monitor or any other electrical
equipment.
· Touch the screen area of your monitor with sharp or abrasive items. This type of
contact may cause permanent damage to your screen.
· Use any cleaner which contains an anti-static solution or similar additives. This
may harm the coating of the screen area.
Do:
· Lightly dampen a soft cloth with water and use this to gently wipe the covers and
the screen.
· Remove grease or finger marks with a damp cloth and a little mild detergent.
