1. Precautions and Safety Notices

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:

 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.

 Use only the special power adapter that comes with this monitor for power input.  Do not try to repair the monitor by yourself, as it contains no user-serviceable parts. Only the

qualified technician can repair it.

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

shock to human bodies.

 Stop using the monitor if the cabinet is damaged. Have it checked by a service technician.  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 glass 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.

The following tips may help you optimize your display:

• Adjust the computer's graphics card so that it outputs a 1440 x 900 @ 60Hz video signal to the LCD display. (Look for instructions on “changing the refresh rate” in the graphics card's user guide.)

• If necessary, make small adjustments using H. POSITION and V. POSITION until the screen image is completely visible. (The black border around the edge of the screen should barely touch the illuminated “active area” of the LCD display.)
