Precautions

Warning on power connections

• 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.

For the customers in the UK

If you use the monitor in the UK, be sure to use the appropriate
UK power cord.

Example of plug types

for 100 to 120 V AC for 200 to 240 V AC for 240 V AC only

The equipment should be installed near an easily accessible outlet.

Installation

Do not install or leave the monitor:

• In places subject to extreme temperatures, for example near a
radiator, heating ve nt, or in direc t su nlight. Subjecting the
monitor to extreme temperatures, such as in an automobile
parked in direct sunlight or near a heating vent, could cause
deformations of the casing or malfunctions.

• In places subject to mechanical vibration or shock.

• Near any equipment that generates a strong magnetic field,
such as a TV or various other household appliances.

• In places subject to inordinate amounts of dust, dirt, or sand, for
example near an open window or an outdoor exit. If setting up
temporarily in an outdoor environ me n t, be sur e to take
adequate precautions against airborne dust and dirt. Otherwise
irreparable malfu nctions could occur.

Handling the LCD screen

• Do not leave the LCD screen facing the sun as it can damage
the LCD screen. Take care when you place the monitor by a
window.

• Do not push on or scratch the LCD screen. Do not place a heavy
object on the LCD screen. This may cause th e screen to lose
uniformity or cause LCD panel malfunctions.

• If the monitor is used in a cold place, a residual image may
appear on the screen. This is not a malfunction. The screen
returns to normal as the temperature rises to a normal operating
level.

• If a still picture is displayed for a long time, a residu al ima ge
may appear for a while. The residual image will eventually
disappear.

• The LCD panel becomes warm during operation. This is not a
malfunction.

Note on the LCD (Liquid Crystal Display)

Please note that the LCD screen is made with high-precision
technology. However, black points or bright points of light (red,
blue, or green) may appear constantly on the LCD screen, and
irregular color ed stripes or brightness may appear on the LCD
screen. This is not malfunction.
(Effective dots: more than 99.99%)

Maintenance

• Be sure to unplug the power cord from the power outlet before
cleaning your mon itor.

• Clean the LCD 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
LCD screen’s coating.

• Clean the cabinet, panel, and controls with a so ft cloth lightly
moistened with a mil d detergent solution. Do not use any type
of abrasive pad, scouring powder, or solvent, such as alcohol or
benzine.

• 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.

• Note that material deterioration or LCD screen coating
degradation may occur if the monitor is exposed to volatile
solvents such as insecticide, or if prolonged co ntact is
maintained with rubber or vinyl materials.

Transportation

• Disconnect all cables from the monitor and grasp the support
and base sections of the display stand firmly with both hands
when transporti ng. If you d rop the mo nitor, yo u may be in jured
or the monitor m a y be damaged.

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

Disposal of the monitor

• Do not dispose of this monitor with general
household waste.

• The fluorescent tube used in this monitor contains
mercury. Disposal of this mon itor must be carried out
in accordance to the regulations of your local
sanitation authority.

The factory preset mode

When the monitor receives an input signal, it automatically
matches the signal to one of the factory preset modes stored in the
monitor’s memory to provide a high quality picture at the center
of the screen. If the in put sign al matc hes the fac tory pre set mode ,
the picture appears on the screen automatically with the
appropriate default adjustmen ts.

If input signals do not match one of the factory
preset modes

When the monitor receives an input signal that does not match one
of the factory preset modes, the automatic picture quality
adjustment function of this monitor is activated to ensure that a
clear picture always app ears on the screen (with in t he following
monitor frequency ranges):
Horizontal frequency: 28–92 kHz
Vertical frequency: 48–85 Hz
Consequently, the first time the monitor receives input signals
that do not match one of the factory preset modes, the monitor
may take a longer time than n ormal to display the picture on the
screen. This adjustment data is automatically stored in memory so
that next time, the monito r will function in the same wa y as when
the monitor receives the sign als that match one of the factory
preset modes.

If you adjust the phase, pitch, and picture position
manually

For some input signals, the automatic picture quality adjustment
function of this monitor may not completely adjust the picture
position, phase, and pitch. In this case, you can set these
adjustments manually (page 15). If you set these adjustments
manually, they are stored in memory as user modes and
