Note: Hand degauss must be used on stand-by or power-off condition.

This model has an automatic earth magnetism correction function by using an earth

magnetism sensor and a LCC coil. When using a hand degauss while monitor (LCC

coil) is being operated, it sometimes gets magnetized, and the system may not work

properly as a result.

• Use the supplied power cord. If you use a different power cord, 

be sure that it is compatible with your local power supply.
For the customers in the U.S.A.
If you do not use the appropriate cord, this monitor will not 
conform to mandatory FCC standards.

• Before disconnecting the power cord, wait at least 30 seconds 

after turning off the power to allow the static electricity on the 
screen’s surface to discharge.

• After the power is turned on, the screen is demagnetized 

(degaussed) for about 2 seconds. This generates a strong 
magnetic field around the screen which may affect data stored 
on magnetic tapes and disks placed near the monitor. Be sure to 
keep magnetic recording equipment, tapes, and disks away 
from the monitor.

Do not install the monitor in the following places:
• on surfaces (rugs, blankets, etc.) or near materials (curtains, 

draperies, etc.) that may block the ventilation holes

• near heat sources such as radiators or air ducts, or in a place 

subject to direct sunlight

• in a place subject to severe temperature changes
• in a place subject to mechanical vibration or shock
• on an unstable surface
• near equipment which generates magnetism, such as a 

transformer or high voltage power lines

• near or on an electrically charged metal surface

• Clean the screen with a soft cloth. If you use a glass cleaning 

liquid, do not use any type of cleaner containing an anti-static 
solution or similar additive as this may scratch the screen’s 
coating.

• Do not rub, touch, or tap the surface of the screen with sharp or 

abrasive items such as a ballpoint pen or screwdriver. This type 
of contact may result in a scratched picture tube.

• Clean the cabinet, panel and controls with a soft cloth lightly 

moistened with a mild detergent solution. Do not use any type 
of abrasive pad, scouring powder or solvent, such as alcohol or 
benzene.

When you transport this monitor for repair or shipment, use the 
original carton and packing materials.

This monitor can be adjusted within the angles shown below. To 
find the center of the monitor’s turning radius, align the center of 
the monitor’s screen with the centering dots on the stand.
Hold the monitor at the bottom with both hands when you turn it 
horizontally or vertically. Be careful not to pinch your fingers at 
the back of the monitor when you tilt the monitor up vertically.

The equipment should be installed near an easily accessible 
outlet.

With the monitor and computer switched off, first connect the 
power cord to the monitor, then connect it to a power outlet.

First turn on the monitor, then turn on the computer.

The installation of your monitor is complete.
If necessary, use the monitor’s controls to adjust the picture.

• Check that the monitor is correctly connected to the computer.
• If NO INPUT SIGNAL appears on the screen, try changing the 

input signal (page 8), and confirm that your computer’s graphic 
board is completely seated in the correct bus slot. 

• If you are replacing an old monitor with this model and OUT 

OF SCAN RANGE appears on the screen, reconnect the old 
monitor. Then adjust the computer’s graphic board so that the 
horizontal frequency is between 30 – 121 kHz, and the vertical 
frequency is between 48 – 160 Hz.

For more information about the on-screen messages, see “Trouble 
symptoms and remedies” on page 18.

To maximize the potential of your monitor, install the new model 
information file from the supplied Windows Monitor Information Disk 
onto your PC.
This monitor complies with the “VESA DDC” Plug & Play standard. If 
your PC/graphics board complies with DDC, select “Plug & Play Monitor 
(VESA DDC)” or this monitor’s model name as the monitor type in the 
“Control Panel” of Windows 95/98. If your PC/graphics board has 
difficulty communicating with this monitor, load the Windows Monitor 
Information Disk and select this monitor’s model name as the monitor 
type.

Monitor setup in Windows NT4.0 is different from Windows 95/98 and 
does not involve the selection of monitor type. Refer to the Windows 
NT4.0 instruction manual for further details on adjusting the resolution, 
refresh rate, and number of colors.

Adjust the monitor’s resolution and color number by referring to your 
computer’s instruction manual. The color number may vary according to 
your computer or video board. The color palette setting and the actual 
number of colors are as follows:
• High Color (16 bit) t 65,536 colors
• True Color (24 bit) t about 16.77 million colors
In true color mode (24 bit), speed may be slower.
