INTRODUCING

YOU

R MONITOR

Please read

this

brief guide carefully before you try to use your

monitor. This manual shows you how to connect the

monitor

and

use

it

in various operating modes. It also explains the picture

controls and gives instructions for the installation, use and

ser-

vice

of

the

1902.

The Commodore

1902

is a full-color dual monitor, meaning it can

display

computer

output

in either

40

- or 80-column screen width.

Some computers, like the Commodore

64

, display screen

output

in a 40-column format. Others, like the Commodore

PC

, require

an

80-column wide screen. The Commodore

128

can display

on

both screen widths.

You

can select t

he

operating mode you want

with the

flick

of

a switch. The switch setting depends on the com-

puter you have hooked up to the

1902

monitor.

The

1902

can be used in four operating modes: two

40

-column

and two aO-column. The

two

40-column modes are composite

and separated. The two aO-column modes are digital

RGB,

posi·

tive and negative sync. The following chart shows recommended

operating modes

by

computer mode. Depending

on

your com-

puter, you'

ll

find that certain operating modes give better dis-

plays while other modes may not even produce a picture.

Be

sure to take note

of

the warnings

in

this manual, and do

NOT

remove the back cover

or

otherwise attempt to service this moni-

tor for safety reasons. If you have problems with your monitor

that

are not covered in this manual, see your Commodore dealer

or a qualified technician.

CONNECTING THE MONITOR

TO

A COMPUTER

The

monitor

connection cable connects your

monitor

to a Com-

modore personal computer. Before you connect the cable, turn

off

the power

to

both your personal

computer

and the monitor.

There are

two

different

cables included

with

the

1902

that you can

use to connect the

monitor

to your computer.

1.

One kind

of

cable has three different-colored

jacks

on one end

and a larger rounded end.

2.

The other cable has a silver end that connects the monitor to

the RGB socket on the back

of

the computer.

Shielded cable must

be

used for the connection between this moni-

tor and your computer.

Shielded cables required for both

RGB

and composite connection.

\\

..

The kind

of

cable you'll use depends on your computer. The three-

plugged video cable is used for 40-column display (for composite

and separated modes). The

RGB

plug connects to the computers

that

use the 80-column operating mode. The

C128

, since

it

uses

both

RGB

and composite operating modes, connects both.

To

find

out

which kind

of

cable you should use, see the above table

and look at the audio/video connector(s) on your computer. See

your

computer

's user manual if you don't know where this con-

nector is.

3

To

connect a three-jack cable to the rear panel

of

the monitor,

follow these instructions, which clarify the diagrams:

1.

Plug the rounded end

with

eight PINS inside (the larger end of

the cable) into the VIDEO connector port on your computer.

Make sure the small dent on the metal end

of

the cable that

you plug into the computer is facing up, and push the cable

end

firmly

in.

2.

Plug the three

jack

ends

of

the cable into the three sockets

on

the back

of

the monitor. The jacks and the sockets are color-

coded:

- the

white

output

jack plugs into the AUDIO socket (WHITE)

on the monitor.

• the

yellow

output

jack

plugs into the VIDEO socket

(YELLOW).

• the

red

output

jack plugs into the CHROMA socket

(RED).

3.

Set the VIDEO MODE SWITCH to SEP (for separated luma and

chroma) for a sharp color 40-column picture display.

SAFETY PRECAUTIONS

This unit has been engineered and manufactured to assure your

personal safety. But

improper use can result

in

potential electri-

cal shock or fire hazards_

In

order not to defeat the safeguards

incorporated in this monitor, observe the following basic rules for

its installation, use and servicing. Follow all warnings and

instructions marked on your video monitor.

INSTALLATION

1.

Your set is equipped with a three-pronged

120

-volt

AC

line

plug. This safety feature allows the plug to

fit

into the power

outlet only one

way.

If

it

is necessary to use a 3-prong to

2-

prong plug adapter, make sure the adapter is properly

grounded according to

its

instructions.

2.

Operate the set only from a power source

as

indicated on the

set

or

refer to the user's manual for this information. If you

are not sure

of

the type

of

power supply to your home, con-

sult your dealer

or

local power company.

3.

Overloaded

AC

outlets and extension cords are dangerous.

So are frayed power cords and broken plugs. They may result

in a shock

or

fire hazard. Call your service technician for

replacement.

4.

Do

not allow anything to rest or roll over the power cord, and

do not pace the set where the power cord is subject to

traffic

or abuse. This may result in a shock or fire hazard.

5.

Do

not use this monitor near

water-for

example, near a bath-

tub, washbowl, kitchen sink, laundry tub, in a wet basement,

or near a swimming pool, etc.

6. Sets are provided with ventilation openings in the cabinet to

allow heat generated during operation to

be

released. If these

openings are blocked, heat built up within the set can cause

failures which may result in a fire hazard.

Therefore:

• Never block the bottom ventilation slots by placing

it

on a

bed, sofa, rug, etc.;

• Never place a set in a

"built-in"

enclosure unless proper

ventilation is provided;

• Never cover the openings with cloth or other material;

• Never place the set near

or

over a radiator or heat register.

10

7.

To

avoid personal injury:

•

Do

not place a set on a sloping shelf unless properly

secured;

• Use

only

a

cart

or

stand

recommended

by

the

manufacturer;

•

Do

not

try

to roll a

cart

with small casters across thresh-

olds or deep-pile carpets.

• Wall- and shelf-mounted installations should use factory

approved instructions.

USE

8.

Always turn the set

off

if it

is necessary to leave the room for

more than a short period

of

time. Never leave a set on when

leaving the house. A malfunction may result in a fire hazard.

9.

Caution children about dropping or pushing objects into the

set's cabinet openings. Some internal parts carry hazardous

voltages and contact can result in a fire or electrical shock.

10

. Unplug the set from the wall outlet before cleaning the face

of

the picture tube. Use a slightly damp (not wet) cloth.

Do

not

use

an

aerosol directly on the picture tube since it may over-

spray and cause electrical shock.

11

. Never add accessories to a set that has not been designed

for this purpose. Such additions may create

an

electrical

shock hazard.

12.

For added protection

of

the set during

an

electrical storm or

when the set is to be left unattended for

an

extended period

of

time, unplug it from the wall outlet. This will prevent shock

and fire hazards due to lightning

or

power-line surges.

13.

Do not bring magnetic devices such

as

magnets or motors

near the picture tube. They may have a negative effect on the

color purity

of

the picture.

14.

Sometimes you may feel static electricity when you touch the

surface

of

the picture tube. This is normal for any

TV

set or

monitor and is harmless to the human body.

11

SERVICE

15.

Unplug the set from the wall outlet and refer servicing to

qualified service personnel under the following conditions:

A.

When the power cord or plug is damaged or frayed.

B.

If liquid has been spilled into the set.

C. If the set has been exposed to rain or water.

D.

If the set does not operate normally

by

following the oper-

ating instructions. Adjust only those controls that are cov-

ered in the operating instructions, as improper adjustment

of

other controls may result in damage and will often

require extensive work by a qualified technician to restore

the set

to

normal operation.

E.

If the set has been dropped or the cabinet has been

damaged.

F.

When the set exhibits a

distinct

change in

performance-

this

indicates a need for servicing.

G.

If snapping

or

popping from the monitor is continuous or

frequent during operation. It is normal for some sets to

make occasional snapping or popping sounds, particularly

when being turned on or off.

16.

Do

not

attempt

to service this

monitor

yourself, as opening or

removing covers may expose you to dangerous voltage or

other hazards. Dangerous high voltage is present even when

the

monitor

is unplugged. Refer all servicing to qualified ser-

vice personnel.

17.

When replacement parts are required, have the service tech-

ni,cian verify in writing that the replacements

he

used have

the same safety characteristics as the original parts. Use

of

manufacturer's specified replacements can prevent fire,

shock

or other hazards.

18.

Upon completion of any service

or

repairs to the set, please

ask the service technician to perform the safety check

described in the manufacturer's service literature.

19.

When a video

monitor

reaches the end

of

its useful life,

improper disposal could result in a picture tube implosion.

Ask a qualified service technician to dispose

of

the set.
