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.
