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.

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?  
Adjust the brightness and the contrast.  
Is the power indicator  
amber?  
If the monitor is in power saving mode, try moving the  
mouse or pressing any key on the keyboard to bring up  
the screen.  
Do you see an "OUT OF  
FREQUENCY" message  
on 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  
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.)  
interlaced mode?  
Do you have any  
magnetic material such  
as adapter, or high-  
voltage line near to your  
monitor?  
Remove magnetic sources, such as power  
adapters, speakers, or high-voltage lines, away from  
the monitor.  
Do you hear a "~ding"  
sound while the monitor  
is flickering?  
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.

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?  
Check the connection of the signal cable. Or pull out the  
video card of the PC and insert it again.  
Do you see black dots on  
the screen?  
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.  
Do you see a partial  
blurring on the screen?  
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:
