Put your monitor only in a lean, cool, dry environment. If it gets wet, unplug the power cable

immediately and consult your closed dealer.

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.

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

When replacing parts or circuit boards, clamp the lead wires around terminals before soldering.

Keep wires away from high voltage, high temperature components and sharp edges.

Keep wires in their original position so as to reduce interference.

Adjustment of this product please refers to the user’ manual.
