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.

WARNINGS:

zThis monitor should be operated only at the correct power sources indicated on the label on the rear

Power Company.

zUse only the special power adapter that comes with this monitor for power input.

zDo not try to repair the monitor by yourself, as it contains no user-serviceable parts. Only the

qualified technician can repair it.

zDo not remove the monitor cabinet. There are high-voltage parts inside that may cause electric shock

to human bodies.

zStop using the monitor if the cabinet is damaged. Have it checked by a service technician.

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

immediately and consult your closed dealer.

zAlways 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 glass screen.

zDo 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

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

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

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