Introduction

Tandy

is

proud

to

present the CM-11, a high-resolution

color

display

monitor

de-

signed

to

display characters and graphics in

16

vivid colors.

The CM-11

has

many advantages over

other

color

monitors. These include:

• Thirteen-inch

color

display

providing

eye-pleasing graphics

• Adjustable picture controls

that

tailor

brightness and contrast

to

suit

environ-

mental lighting

• Unique, selective

light

transmission properties

which

reduce the effects

of

ambient

light

while maintaining true

color

purity,

even

under harsh

lighting

conditions

• Sharp,

"flicker-free"

image provided

by

non-interlaced

circuitry

• RGB direct-drive signal system

that

provides

640-dot

by

225-line display

for

crisp characters and vivid

color

graphics

Description

of

the CM-11

Care and Maintenance

Your

CM-11

should give you a long period of trouble-free service

if

it

is

connected

to

the

proper power source and handled gently. However,

if

the

monitor

malfunctions,

have it checked by a qualified Radio Shack service technician.

Installation and Location Hints

The

CM-11

has openings for ventilation purposes,

to

provide reliable

operation

of

the

monitor

and

protect

it from overheating.

• Install

the

monitor

at

least

4"

(0.1 meters) away from

the

wall.

• Never cover

the

openings with cloth

or

other

fabric.

• Never block

the

openings on

the

bottom

of

the

monitor

by

placing it

on

a bed,

sofa, rug, etc.

• Never place

the

monitor

in

a built-in enclosure unless proper ventilation

is

pro-

vided.

• Never place

the

monitor

near

or

over a radiator

or

heat

register.

• Never expose

the

monitor

to

rain, excessive moisture,

or

excessive

dust.

Moisture

and

dust

create shock and fire hazards.

• Never place

the

monitor

on an unstable desk, cart,

or

stand.

Operation Hints

• Operate

the

monitor

only from the power source indicated

on

the

back

of

the

cabinet.

Use

of

a power source

that

is

not

marked

on

the

monitor

can cause

monitor

damage, as well

as

improper operation.

•

To

ensure safe operation,

the

3-pin plug (supplied) must be inserted into a stand-

ard 3-pin AC

outlet

which

is

effectively grounded. Extension cords used

with

the

equipment

must

be 3-wire and correctly wired

to

provide

connection

to

ground.

Improperly wired extension cords are a major cause

of

fatalities.

The

fact

that

the

equipment

operates satisfactorily does

not

imply

that

the

power

point

is

grounded

and

that

the

installation

is

completely safe.

For

your

safety,

if

in

any

doubt

about

the

effective grounding

of

the

power point, consult a qualified electrician.

•

To

prevent a fire

or

electrical shock,

do

not

overload wall outlets

and

extension

cords.

• Adjust only those controls

that

are described

in

the

section "Adjusting

the

CM-11

Display." Improper adjustment

of

other

controls can result

in

damage

that

will

require

the

services

of

a technician.

• Do

not

allow anything

to

rest on

the

power

cord.

The

cord should

not

stretch

across a hall

or

any

other

high-traffic area.

7

Care and Maintenance

• Unplug

the

monitor

from

the

AC

outlet

if

it

is

to

be idle during a

weekend,

vaca-

tion,

or

other

extended

period

of

time.

• If

the

same

characters

or

graphics are

shown

for

a long

time

with

the

8

RIGHT

and

CONTRAST

controls

set

to

maximum

positions,

part

of

the

screen

may

be

damaged. Use

these

controls

with

care.

•

To

prevent

electrical

shock

and

other

hazards,

do

not

remove

the

back

cover

of

the

monitor.

•

Do

not

drop

or

push

objects

into

the

cabinet

openings.

Some

internal

parts

carry

hazardous

voltages

and

contact

can

result

in

electrical

shock

or

fire.

• Never spill a liquid

of

any

kind

on

the

monitor.

If liquid

is

accidentally spilled, un-

plug

the

set

and

have

it

checked

by

a Radio

Shack

service technician before using.

Cleaning Hints

Always

unplug

the

monitor

before

cleaning. Wipe

the

screen

and

cabinet

with

a

soft

cloth.

If

the

screen requires

more

than

dusting,

use a household

window

cleaner

and

a

soft

cloth.

Caution: Do

not

use

benzene,

thinner,

or

any

volatile substances

to

clean

the

unit.

Such

substances

can

permanently

mar

the

finish. Never leave

the

unit

in

contact

with

rubber

or

vinyl

for

an

extended

period.

Occasionally,

the

internal

parts

of

the

monitor

may need

to

be cleaned

to

prevent

a fire

and

other

damage

caused

by

dust

particles. It

is

recommended

that

you

take

the

unit

to

a

Radio

Shack

Computer

Center

for

a yearly cleaning.

to

a

computer

with

other

than the

specified

input

signal,

distortion

in the display image, shape, and

position

may

be

due

to

the inadequate

signal

of

some computers. The
