SAFETY
Note: Note the following safety precautions before using this monitor.
Electrical
Check the Voltage  This product should be operated from the type of power indicated on the marking
label. If you are not sure of the type of power available, consult your dealer or local
power company.
Electrical Shock  This product is equipped with a 3-wire grounding-type plug, a plug having a third
(grounding) pin. This plug will only fit into a grounding-type power outlet. This is a
safety feature. If you are unable to insert the plug into the outlet, contact your
electrician to replace your obsolete outlet. Do not defeat the purpose of the
grounding-type plug.
 To prevent electrical shock, do not insert any metal object into any opening in the LCD
monitor casing.
 Do not attempt to service this product yourself, as opening or removing covers may
expose you to dangerous voltage points or other risks. Refer all servicing to qualified
service personnel.
 If the power cord is damaged, do not use the LCD monitor. Do not place any object on
the power cord, and place the power cord away from crowded areas.
 While pulling the LCD monitor plug away from the socket on the wall, hold the plug not
the power cord.
 Do not expose the LCD monitor to rain and do not use in environments near water
(such as in the kitchen, or near a swimming pool).
 If the LCD monitor becomes wet, unplug the power cord immediately and contact a
Service Center.
Unusual conditions  If the LCD monitor begins to perform abnormally, makes a noise, or emits smoke or
odors, unplug it immediately and contact a service center.

the openings should not be blocked or covered. Do not place the LCD monitor on a
bed, sofa, blanket or other soft surfaces; as soft objects may block the vents in the
LCD monitor.
 If you place the LCD monitor on a bookshelf or other enclosed space, it is essential to
leave an air-space of 4-inches (10cm) between the monitor and the enclosure.
