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.

Function descriptions
OSD Lock short cuts function for the buttons
The OSD lock will be activated by pressing the front panel control buttons "(1), & (▲)" for 10
seconds. If the user then tries to access the OSD by pressing any of the buttons "1", "▼",
"▲", "2" a message will appear on the screen for 3 seconds showing "OSD Locked". The
OSD lock will be deactivated by pressing the front panel control buttons "(1), & (▲)" again for
10 seconds.
Note1: When the OSD is locked will lock all functions, including “Volume” and “Mute”
Note 2: Status bar indicating OSD Lock or Unlock is in progress and when complete it will
indicate “OSD Locked”
Note 3: OSD Lock should not lock Power Button and Power Lock function
Power Lock short cuts function for the buttons
The power button lock will be activated by pressing the front panel control buttons "(1), & (▼)" for
10 seconds. Locking the power button means that the user won't be able to turn off the LCD
while the power button is locked. If the user presses the power button while it is locked, a
message will appear on the screen for 3 seconds showing "Power Button Locked". It also means
that with the power button locked, the LCD would automatically turn back "On" when power is
restored after a power failure. If the power button is not in the locked mode, then power should
return to it's previous state when power is restored after a power failure. The power button lock
will be deactivated by pressing the front panel control buttons "(1), & (▼)" again for 10 seconds.
Note 1: Status bar indicating Power Button lock or unlock is in progress and when complete it
will indicate “Power Button Locked”
Note 2: Power should only be lockable in the “On State”
Memory Recall Actions
Memory Recall action on the analog and digital mode as below
1. Recall white balance to factory setting
2. Set the factory defaults as shown in Section 4-8
3. Clean all the mode setting buffer
4. Execute Auto Image Adjust
Note: Memory Recall should have no effect for Language, Power Lock, User Color Settings or

Do the following to adjust the display setting:
1. To display the Main Menu, press button [1].
NOTE: All OSD menus and adjustment screens disappear automatically after about 15
seconds. This is adjustable through the OSD timeout setting in the setup menu.
2. To select a control to adjust, pressSorTto scroll up or down in the Main Menu.
3. After the desired control is selected, press button [2]. A control screen like the one shown
below appears.
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.
4. To adjust the setting, press the up S or down T buttons.
5. To save the adjustments and exit the menu, press button [1] twice.
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.)
