Important Safety Notice
1. Safety precautions
This monitor is manufactured and tested on a ground principle that a user’s safety
comes first. However, improper used or installation may cause damage to the
monitor as well as to the user.
Warning:
z This monitor should be operated only at the correct power sources indicated on
the label on the rear of the monitor. If you’re unsure of the power supply in you
residence, consult your local dealer or Power Company.
z Do not try to repair the monitor by yourself, as it contains no user-serviceable
parts. This monitor should only be repaired by a qualified technician.
z Do not remove the monitor cabinet. There are high-voltage parts inside that may
cause electric shock to human bodies.
z Stop using the monitor if the cabinet is damaged. Have it checked by a service
technician.
z Put your monitor only in a lean, cool, dry environment. If it gets wet, unplug the
power cable immediately and consult your closed dealer.
z Always unplug the monitor before cleaning it. Clean the cabinet with a clean, dry
cloth. Apply non-ammonia based cleaner onto the cloth, not directly onto the
class screen.
z Do not place heavy objects on the monitor or power cord.
2. Product safety notice
Many electrical and mechanical parts in this chassis have special safety visual
inspections and the protection afforded by them cannot necessarily be obtained by
using replacement components rated for higher voltage, wattage, etc. Before
replacing any of these components read the parts list in this manual carefully. The
use of substitute replacement parts, which do not have the same safety
characteristics as specified in the parts list, may create shock, fire, or other hazards.
3. Service notes
z When replacing parts or circuit boards, clamp the lead wires around terminals
before soldering.
z Keep wires away from high voltage, high temperature components and sharp
edges.
z Keep wires in their original position so as to reduce interference.
z Adjustment of this product please refers to the user’ manual.
