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, please use the appropriate UK

power cord.

Installation

Do not install or leave the monitor:

• In places subject to extreme temperatures, for example near a

radiator, heating vent, or in direct sunlight. 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 environment, be sure to take

adequate precautions against airborne dust and dirt. Otherwise

irreparable malfunctions 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 the 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 residual image

may appear for a while. The residual image will eventually

disappear.

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

malfunction.

About the bright points of light or black dots

Bright points of light (red, blue or green) or black dots

may appear on the LCD screen. This is not a

malfunction. The LCD screen is made with high-

precision technology and more than 99.99 % of the

picture element is intact. However, some of the picture

element may not appear or some of the picture element

may appear constantly.

Maintenance

• Be sure to unplug the power cord from the power outlet before

cleaning your monitor.

• 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 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

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 contact is

maintained with rubber or vinyl materials.

Transportation

• Disconnect all cables from the monitor when transporting.

When you transport this display, grasp the support and base

sections of the display stand firmly with both hands. Also use

both hands when carrying the media engine. If you drop the

monitor, you may be injured or the monitor may be damaged.

• When you transport this monitor for repair or shipment, use the

original carton and packing materials.

Replacement of the fluorescent tube

A specially designed fluorescent tube is installed as the lighting

apparatus for this monitor. If the screen becomes dark, unstable,

or does not turn on, replace the fluorescent tube with a new one.

Consult your Sony dealer when replacing the fluorescent tube.

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 monitor must be carried out

in accordance to the regulations of your local

sanitation authority.

The equipment should be installed near an easily accessible

outlet.

Example of plug types

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

To adjust the tilt and height

This display can be adjusted within the angles shown below.

To adjust the angles, grasp the lower sides of the LCD panel with

both hands as shown below. Tilt the LCD panel adequately

backward, then lift the LCD panel upward to the desired screen

height, then adjust the screen tilt as desired. When adjusting the

screen height and tilt, proceed slowly and carefully, being sure not

to hit the LCD panel against the desk or the base of the display

stand.

To use the display comfortably

This display is designed so that you can set it up at a comfortable

viewing angle. Adjust the viewing angle of your display

according to the height of the desk and chair, and so that light is

not reflected from the screen to your eyes.

To enjoy clear sound from the built-

in stereo speaker

This monitor has a built-in stereo speaker in base of the display

stand.

We recommend that you position the LCD panel slightly away

from the display stand. High tones from the speaker may be

muffled if the LCD panel is positioned immediately on top of the

stand. Be careful not to drop any metal object into the speaker's

vents as the speakers generate a magnetic field. Also, this

magnetic field may affect data stored on magnetic tapes and discs.

Be sure to keep magnetic recording equipment, tapes, and floppy

discs away from the speaker’s opening.

A duct is provided on the rear part of the display stand to boost the

bass. Be sure not to block the duct with paper or other objects to

ensure clear sound.

When the monitor receives an input signal, the automatic picture

quality adjustment function of this monitor automatically adjusts

the picture position, phase, and pitch, and ensures that a clear

picture appears on the screen. For more information about this

function, see “Automatic picture quality adjustment function” on

Adjusting the color temperature

(COLOR)

The COLOR settings allow you to adjust the picture’s color

temperature by changing the color level of the white color field.

Colors appear reddish if the temperature is low, and bluish if the

temperature is high.

9300K is generally suitable for word processing and other text

oriented applications, and 6500K is generally suitable for video

images.

You can set the color temperature to 5000K, 6500K, 9300K or

user adjustment.

1Press the MENU button.

The main menu appears on the screen.

2Press the M(+)/m(–) buttons to select (COLOR)

and press the OK button.

The COLOR menu appears on the screen.

3Press the M(+)/m(–) buttons to select the desired

color temperature.

The preset color temperatures are 5000K, 6500K, and 9300K.

Since the default setting is 9300K, the whites will change

from a bluish hue to a reddish hue as the temperature is

lowered to 6500K and 5000K.

You can set separate color temperatures for each of the video

input signals.

4If necessary, fine tune the color temperature.

First press the M(+)/m(–) buttons to select ADJUST and

press the OK button. Then press the M(+)/m(–) buttons to

select R (Red) or B (Blue) and press the OK button, and then

press the M(+)/m(–) buttons to adjust the color temperature.

Since this adjustment changes the color temperature by

increasing or decreasing the R and B components with respect

to G (green), the G component is fixed.

If you fine tune the color temperature, the new color setting is

stored in memory for USER ADJUSTMENT and

automatically recalled whenever USER is selected.

The USER ADJUSTMENT setting is common to both the

input signals. If you change the user adjustment setting for

one input signal, the setting for the other input signal is also

changed.
