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.)
The command line at the bottom of the
control screen tells what to do next from
this screen. You can toggle between control
screens, adjust the selected option, or exit
the screen.
