Important Precautions This unit has been engineered and manufactured to ensure your personal safety, however improper use may result in potential eletrical shock or fire hazards. In order to allow the proper operation of all safeguards incorporated in this monitor, observe the following basic rules for its installation, use, and servicing. Keep it in an accessible place for future reference. On Safety Use only the power cord supplied with the unit. In case you use another power cord, make sure that it is certified by the applicable national standards if not being provided by the supplier. If the power cable is faulty in any way, please contact the manufacturer or the nearest authorized repair service provider for a replacement. The power supply cord is used as the main disconnect device. Ensure that the socket-outlet is easily accessible after installation. Operate the monitor only from a power source indicated in the specifications of this manual or listed on the monitor. If you are not sure what type of power supply you have in your home, consult with your dealer. Overloaded AC outlets and extension cords are dangerous. So are frayed power cords and broken plugs. They may result in a shock or fire hazard. Call your service technician for replacement. Hands must be dry when holding the power plug to avoid an electric shock. Do not damage the power cord by disassembling, bending, pulling or heating up. It can cause fire or electric shock. Make sure to completely insert the power plug. Insecure connections can cause fire. Do not Open the Monitor. There are no user serviceable components inside. There are Dangerous High Voltages inside, even when the power is OFF. Contact your dealer if the monitor is not operating properly. To Avoid Personal Injury :
Do not place the monitor on a sloping shelf unless properly secured. Use only a stand recommended by the manufacturer. Do not try to roll a stand with small casters across thresholds or deep pile carpets. A1 Important Precautions To Prevent Fire or Hazards:
Always turn the monitor OFF if you leave the room for more than a short period of time. Never leave the monitor ON when leaving the house. Keep children from dropping or pushing objects into the monitor's cabinet openings. Some internal parts carry hazardous voltages. Do not add accessories that have not been designed for this monitor. During a lightning storm or when the monitor is to be left unattended for an extended period of time, unplug it from the wall outlet. Do not bring magnetic devices such as magnets or motors near the picture tube. On Installation Do not allow anything to rest upon or roll over the power cord, and do not place the monitor where the power cord is subject to damage. Do not use this monitor near water such as near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, or near a swimming pool. Monitors are provided with ventilation openings in the cabinet to allow the release of heat generated during operation. If these openings are blocked, built-up heat can cause failures which may result in a fire hazard. Therefore, NEVER:
Block the bottom ventilation slots by placing the monitor on a bed, sofa, rug, etc. Place the monitor in a built-in enclosure unless proper ventilation is provided. Cover the openings with cloth or other material. Place the monitor near or over a radiator or heat source. Do not install the monitor in a dusty area. It can cause fire. On Cleaning Unplug the monitor before cleaning the face of the monitor screen. Use a slightly damp (not wet) cloth. Do not use an aerosol directly on the monitor screen because overspray may cause electrical shock. On Repacking Do not throw away the carton and packing materials. They make an ideal container in which to transport the unit. When shipping the unit to another location, repack it in its original material.

A5 A6 A7 A8 A9 A10 A11 A12 Troubleshooting Check the following before calling for service. No image appears Is the power cord of the monitor connected?
Check and see if the power cord is connected properly to the power outlet. Is the power indicator light on?
Press the Power button. Is the power on and the power indicator green?
Is the power indicator flickering?
Do you see an "OUT OF FREQUENCY" message on the screen?
Adjust the brightness and the contrast. If the monitor is in power saving mode, try moving the mouse or pressing any key on the keyboard to bring up the screen. This message appears when the signal from the PC
(video card) is out of horizontal or vertical frequency range of the monitor. See the 'Specifications' section of this manual and configure your monitor again. Do you see a "SELF DIAGNOSITICS" message on the screen?
This message appears when the signal cable between your PC and your monitor is not connected. Check the signal cable and try again. The screen is flickering. Is the vertical frequency less than 70Hz or is your monitor set to the interlaced mode?
Do you have any magnetic material such as adapter, or high-
voltage line near to your monitor?
Do you hear a "~ding"
sound while the monitor is flickering?
Set the vertical frequency to 72Hz or higher, and consult the video card user manual for instructions on converting to a non-interlaced mode.
(You can set this option under the Display icon of the Control Panel.) Remove magnetic sources, such as power adapters, speakers, or high-voltage lines, away from the monitor. Use the normal degaussing function. This function clears the screen and reduces any screen blur that may occur due to the surrounding magnetic field. The screen may flicker for about 5 seconds, accompanied by a "~ding" sound. A13 Troubleshooting The screen color is not normal. Do you see basic discoloration (16 colors)?
Set the color depth to 256 colors or higher: use 'Control Panel' -> 'Display' -> 'Settings' -> 'Color Palette'
Is the screen color unstable or monochrome?
Do you see black dots on the screen?
Do you see a partial blurring on the screen?
Check the connection of the signal cable. Or pull out the video card of the PC and insert it again. This is due to a small amount of foreign or abnormally florescent material that became fastened on the mask during manufacturing. It will not affect product performance. This happens due to interference from surrounding magnetic fields, as created when speakers, steel structures, or high-voltage lines are placed near the monitor. Remove any such materials from the immediate vicinity and use the DEGAUSS icon on the screen adjustment menu to fix the screen. I see an after-image on the screen. Do you see the after-
image even when you turn off the monitor?
A premature aging of the monitor pixels may cause the prolonged display of a single image on the screen. Be sure to use a screen saver to maximize the service life of the monitor. I see waves on the screen. Do you see the wave directly on the screen?
This occurs in inverse proportion to the screen focus, which can be caused by a particular frequency or video card. Brighten the screen and use the 'MOIRE' icon on the screen adjustment menu to adjust the screen. Have you installed the monitor driver?
Have you installed the monitor driver?
Be sure to install the monitor driver from the monitor driver CD (or diskette) that comes with your monitor. Or, you can also download the driver from our web site:
