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.

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?

Is the power indicator light
on?

Is the power on and the

power indicator green?
Is the power indicator

amber?

Do you see an "OUT OF

FREQUENCY" message
on the screen?

Do you see a

"NO SIGNAL"message

on the screen?

Check and see if the power cord is connected properly to

the power outlet.

Press the Power button.

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.

Press the digital select button.

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.

This message appears when the signal cable between

your PC and your monitor is not connected. Check the
signal cable and try again.

Or press the "Digital" button to choose another input

signal.

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 high­voltage 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.

The screen is flickering.
