This monitor has three modes of reduced power

consumption. By sensing the absence of video signal

coming from the computer, it reduces power consumption

as follows.

Note

If the video signal cable is not connected, the "NO INPUT

SIGNAL" message (page 18) appears. After 30 seconds, the

power saving function automatically puts the monitor into the

active-off mode and the u indicator lights up orange. Once

the horizontal and vertical sync signals are detected, the

monitor automatically resumes its normal operation mode.

This monitor is equipped with a self-diagnosis function. Use

this function if there is a problem with your monitor or

computer.

1 Disconnect the video input cable or turn off the

connected computer.

2 Turn the monitor off and on.

3 Press and hold the >/ button for 2 seconds.

If all four color bars appear (white, red, green, blue) after

a few seconds, the monitor is working properly but there

might be a problem with your computer. Contact your

computer's manufacturer.

If the color bars do not appear, there is a potential

monitor failure. Inform your authorized Sony dealer of

the monitor's condition.

SECTION 1

GENERAL

The operating instructions mentioned here are partial abstracts

from the Operating Instruction Manual. The page numbers of

the Operating Instruction Manual remain as in the manual.

1-1

Getting Started

Warningonpowerconnection

· Use an appropriate power cord for 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.

Examples of plug types:

· Before disconnecting the power cord, wait at least 30

seconds after turning off the power to allow the static

electricity on the CRT display surface to discharge.

· After the power has been turned on, the CRT is

demagnetized (degaussed) for about 5 seconds. This

generates a strong magnetic field around the metal frame,

which may affect the data stored on magnetic tapes and

disks near the bezel. Place magnetic recording equipment,

tapes and disks away from this monitor.

The outlet should be installed near the equipment

and be easily accessible.

Precautions

Installation

· Prevent internal heat build-up by allowing adequate air

circulation. Do not place the monitor on surfaces (rugs,

blankets, etc.) or near materials (curtains, draperies) that

may block the ventilation holes.

· Do not install the monitor near heat sources such as

radiators or air ducts, or in a place subject to direct

sunlight, excessive dust, mechanical vibration or shock.

· Do not place the monitor near equipment which generates

magnetism, such as a transformer or high voltage power

lines.

Maintenance

· 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.

· 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.

Transportation

When you transport this monitor for repair or shipment, use

the original carton and packing materials.

UseoftheTilt-Swivel

With the tilt-swivel, this monitor can be adjusted to the

desired angle within 180° horizontally and 20° vertically.

To turn the monitor vertically and horizontally, hold it at

the bottom with both hands as illustrated below.
