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.

may harm the coating of the screen area.

Understanding power management
Power management is invoked when the computer recognizes that you have not used
your mouse or keyboard for a user-definable period. There are several states as
described in the table below.
For optimal performance, switch off your monitor at the end of each working day, or
whenever you expect to leave it unused for long periods during the day.
