TIMING SPECIFICATION

Power Saving Function

This display meets the power saving guidelines set by the International

ENERGY STAR Program. It is capable of reduced power consumption

when used with a computer equipped with Display Power Management

Signaling (DPMS). By sensing the absence of the sync signal coming

from the computer, it will reduce the power consumption as follows:

CAUTION

The Power Saving function will automatically put the display into Deep Sleep mode if the

power switch is turned on without any video signal input. Once the horizontal and vertical

syncs are sensed, the display will automatically return to its Normal Operation mode.

LEAKAGE TEST

The AC leakage from any exposed metal part to earth ground

and from all exposed metal parts to any exposed metal part hav-

ing a return to chassis, must not exceed 0.5 mA (500

microampers).

Leakage current can be measured by any one of three methods.

1. A commercial leakage tester, such as the Simpson 229 or

RCA WT-540A. Follow the manufacturers' instructions to

use these instruments.

2. A battery-operated AC milliammeter. The Data Precision

245 digital multimeter is suitable for this job.

3. Measuring the voltage drop across a resistor by means of a

VOM or battery-operated AC voltmeter. The "limit" indica-

tion is 0.75 V, so analog meters must have an accurate low-

voltage scale. The Simpson 250 and Sanwa SH-63Trd are

examples of a passive VOMs that are suitable. Nearly all

battery operated digital multimeters that have a 2 V AC

range are suitable. (See Fig. A)

WARNING!!

NEVER TURN ON THE POWER IN A CONDITION IN

WHICH THE DEGAUSS COIL HAS BEEN REMOVED.

SAFETY-RELATED COMPONENT WARNING!!

ATTENTION AUX COMPOSANTS RELATIFS À LA

SÉCURITÉ!!

LES COMPOSANTS IDENTIFIÉS PAR UNE TRAME ET

After correcting the original service problem, perform the fol-

lowing safety checks before releasing the set to the customer:

1. Check the area of your repair for unsoldered or poorly-sol-

dered connections. Check the entire board surface for solder

splashes and bridges.

2. Check the interboard wiring to ensure that no wires are

"pinched" or contact high-wattage resistors.

3. Check that all control knobs, shields, covers, ground straps,

and mounting hardware have been replaced. Be absolutely

certain that you have replaced all the insulators.

4. Look for unauthorized replacement parts, particularly tran-

sistors, that were installed during a previous repair. Point

them out to the customer and recommend their replacement.

5. Look for parts which, though functioning, show obvious

signs of deterioration. Point them out to the customer and

recommend their replacement.

6. Check the line cords for cracks and abrasion. Recommend

the replacement of any such line cord to the customer.

7. Check the B+ and HV to see if they are specified values.

Make sure your instruments are accurate; be suspicious of

your HV meter if sets always have low HV.

8. Check the antenna terminals, metal trim, "metallized"

knobs, screws, and all other exposed metal parts for AC

Leakage. Check leakage as described below.

Introduction

Congratulations on your purchase of a Sony Multimedia CPD-101VS

display!

This display incorporates over 25 years of Sony experience with Trinitron

display technology, ensuring excellent performance and outstanding

reliability.

This display's wide scan range (30 70 kHz), together with Digital

Multiscan Technology, allows it to sync to any video mode from

standard VGA through VESA 1024

× 768 at 85 Hz (VESA 1280 × 1024 at

60 Hz).

In addition, its four factory-preset color modes give you unprecedented

flexibility in matching on-screen colors to hard copy printouts.

Furthermore, it features:

· Graphic Picture Enhancement function

improves monitor performance to match the application that you are

running.

With the GPE AUTO MODE, you can use "IntelliLight" compatible

software which will maximize the color and brightness of a window

running a multimedia presentation without affecting the brightness

and contrast of text based applications.

· Integrated stereo speakers with Bass Boost

enables you to enjoy excellent sound reproduction via 3.0 W stereo

speakers.

All together, CPD-101VS delivers incredible performance with the

quality and support you can expect from Sony.

Plug and play

This display complies with DDCTM1 and DDC2B which are the Display

Data Channel (DDC) standards of VESA.

When a DDC1 host system is connected, the display synchronizes with

the V. CLK in accordance with the VESA standards and outputs the

EDID (Extended Display Identification Data) to the data line.

When a DDC2B host system is connected, the display automatically

switches to DDC2B communication.

DDCTM is a trademark of Video Electronics Standard Association.

Introduction

Installation

· Prevent internal heat build-up by allowing adequate air circulation.

Do not place the unit on surfaces (rugs, blankets, etc.) or near

materials (curtains, draperies) that may block the ventilation holes.

· Do not install the unit near heat sources such as radiators or air ducts,

nor in a place subject to direct sunlight, excessive dust, mechanical

vibration or shock.

· Do not place the unit near equipment which generates magnetism,

such as a converter or high voltage power lines.

Maintenance

· Clean the cabinet, glass 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, like a ball point pen or a screwdriver, as this type of

contact may result in a scratched picture tube.

Transportation

· Do not discard the carton and packing materials. When transporting

the unit, use these packing materials so that the unit is properly

packaged.

· When carrying the unit, be careful not to get your hands caught

between the display and the tilt-swivel.

Precautions

Warning on Power Connection

· Use the supplied power cord.

For the customers in U.S.A.

If you do not do this, this display will not conform to mandatory FCC

standards.

For the customers in UK.

If you use the display in the UK, please use the supplied UK cable

with the UK plug.

for 100 to 120 V AC

for 220 to 240 V AC

for 240 V AC only

· Before disconnecting the power cord, wait at least 30 seconds after

turning off the power switch to discharge static electricity from the

CRT display surface.

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

approximately 5 seconds. This generates a strong magnetic field

around the bezel which may affect the data stored on magnetic tape or

disks near the bezel. Place such magnetic recording equipment and

tapes/disks at a distance from this unit.

The socket-outlet shall be installed near the equipment and shall be

easily accessible.
