Safety Precautions and Maintenance
FOR OPTIMUM PERFORMANCE, PLEASE NOTE
THE FOLLOWING WHEN SETTING UP AND
USING THE MULTISYNC LCD COLOUR MONITOR:
•DO NOT OPENTHE MONITOR. There are no user serviceable parts
inside and opening or removing covers may expose you to dangerous
shock hazards or other risks.Refer all servicing to qualified service
personnel.
•Do not spill any liquids into the cabinet or use your monitor near water.
•Do not insert objects of any kind into the cabinet slots, as they may
touch dangerous voltage points, which can be harmful or fatal or may
cause electric shock, fire or equipment failure.
•Do not place any heavy objects on the power cord. Damage to the cord
may cause shock or fire.
•Do not place this product on a sloping or unstable cart, stand or table, as
the monitor may fall, causing serious damage to the monitor.
•Do not place any objects onto the monitor and do not use the monitor
outdoors.
•The inside of the flourescent tube located within the LCD monitor
contains mercury. Please follow the bylaws or rules of your municipality
to dispose of the tube properly.
Immediately unplug your monitor from the wall outlet and refer servicing to
qualified service personnel under the following conditions:
•When the power supply cord or plug is damaged.
•If liquid has been spilled, or objects have fallen into the monitor.
•If the monitor has been exposed to rain or water.
•If the monitor has been dropped or the cabinet damaged.
•If the monitor does not operate normally by following operating
instructions.
•Do not bend power cord.
•Do not use monitor in high temperatured, humid, dusty, or oily areas.
•Do not cover vent on monitor.
•If monitor is broken, do not come in contact with the liquid crystal.
•If glass is broken.Handle with care.

English-17
English
CAUTION
•Allow adequate ventilation around the monitor so that
heat can properly dissipate. Do not block ventilated
openings or place the monitor near a radiator or other
heat sources. Do not put anything on top of monitor.
•The power cable connector is the primary means of
detaching the system from the power supply.The
monitor should be installed close to a power outlet which
is easily accessible.
•Handle with care when transporting. Save packaging for
transporting.
CORRECT PLACEMENT AND ADJUSTMENT OF
THE MONITOR CAN REDUCE EYE, SHOULDER
AND NECK FATIGUE. CHECK THE FOLLOWING
WHENYOU POSITION THE MONITOR:
•For optimum performance, allow
20 minutes for warm-up.
•Adjust the monitor height so that the top of
the screen is at or slightly below eye level.
Your eyes should look slightly downward
when viewing the middle of the screen.
•Position your monitor no closer than 40 cm
and no further away than 70 cm from your
eyes.The optimal distance is 53 cm.
•Rest your eyes periodically by focusing on
an object at least 6 m away. Blink often.
•Position the monitor at a 90°angle to windows and other light sources to
minimize glare and reflections. Adjust the monitor tilt so that ceiling lights
do not reflect on your screen.
•If reflected light makes it hard for you to see your screen, use an
antiglare filter.
•Clean the LCD monitor surface with a lint-free, non-abrasive cloth. Avoid
using any cleaning solution or glass cleaner!
•Adjust the monitor’s brightness and contrast controls to enhance
readability.
•Use a document holder placed close to the screen.
•Position whatever you are looking at most of the time (the screen or
reference material) directly in front of you to minimize turning your head
while you are typing.

English-18
•Avoid displaying fixed patterns on the monitor for long periods of time to
avoid image persistence (after-image effects).
•Get regular eye checkups.
Ergonomics
To realize the maximum ergonomics benefits, we recommend the following:
•Use the preset Size and Position controls with standard signals.
•Use the preset Colour Setting.
•Use non-interlaced signals with a vertical refresh rate between
60-75 Hz.
•Do not use primary colour blue on a dark background, as it is difficult to
see and may produce eye fatigue to insufficient contrast.
