Preface

Congratulations

on

purchasing

the

MZ-800

computer.

Your

MZ-800

is

a

compact

personal

graphics,

16-colour

display,

and

a

programmable

sound

genera-

tor

(PSG)

which

can

generate

3-tone

chords

over

6

octaves.

One

of

the

excellent

features

of

the

MZ-800

is

that

it

contains

hardware

which

makes

it

compatible

with

the

MZ-700

series

computer.

This

makes

it

possible

for

you

to

use

most

of

the

1.2

Handling

1)

This

computer

uses

many

precision

parts.

Do

not

use

or

store

it

in

extremely

hot

or

cold

condi-

tions,

or

under

conditions

where

the

temperature

changes

rapidly.

2)

Do

not

use

or

store

the

computer

in

damp

or

dusty

places,

and

avoid

exposing

it

to

corrosive

chem-

icals

or

gases.

3)

Do

not

block

the

ventilation

holes

or

place

large

objects

nearby

that

will

disrupt

ventilation.

4)

Do

not

subject

the

computer

to

shock

or

vibration.

5)

Do

not

expose

the

computer

to

direct

sunlight.

6)

Do

not

allow

water

or

other

liquid

to

enter

the

cabinet.

Using

the

computer

when

it

is

wet

is

very

dangerous,

and

will

damage

the

computer’s

electronics.

7)

Do

not

disassemble

the

cabinet

unless

you

are

installing

options

as

instructed

by

documents

from

SHARP.

8)

Radios

and

TV

sets

may

pick

up

interference

from

RF

(radio

frequency)

noise

generated

by

the

computer.

Keep

such

equipment

(other

than

that

you

may

be

using

as

the

computer’s

display

unit)

well

away

from

the

computer.

9)

When

peripheral

devices

are

connected,

the

display

image

may

jitter.

If

this

problem

occurs,

change

the

layout

of

your

system’s

equipment.

10)

Do

not

place

any

object

other

than

the

optional

plotter/printer

(MZ-1P16)

on

the

cabinet.

11)

After

turning

off the

power

switch,

unplug

the

power

cable

by

grasping

the

plug

molding,

not

the

cable.

12)

Make

sure

that

you

turn

off

the

power

switch

when

you

not

using

the

computer.

After

turning

off

the

power

switch,

wait

at

least

10

seconds

before

turning

it

on

again,

otherwise

the

system

may

not

operate

properly.

13)

Use

a

dry

soft

cloth

to

clean

the

unit.

Do

not

use

a

wet

cloth

or

volatile

fluids

such

as

alcohol

or

benzene.

Discolouration

or

deformation

of

the

cabinet

may

result

if

this

precaution

is

ignored.

14)

If

you

notice

any

abnormal

condition

such

as

an

extremely

high

temperature,

an

abnormal

odour,

or

smoke,

stop

what

you

are

doing

and

quickly

turn

off

the

power

then

unplug

the

power

cable.

Setup

To

operate

your

MZ-800

computer,

you

must

first

set

up

the

system.

To

do

this,

you

will

need

to

con-

nect

a

display

unit

to

see

what

the

computer

is

doing.

SHARP

supplies

several

types

of

display

units

for the

MZ-800

computer,

or

you

can

use

an

ordinary

home

TV

set

providing

it

can

receive

the

VHF

band.

The

minimum

configuration

your

computer

can

operate

with

is

shown

below:

The

following

explanation

shows

the

setup

procedure

for

a

typical

system.

(1)

Using

a

TV

set

To

use

a

TV

set

as

display

unit,

use the

monitor

cable

provided

with

your

MZ-800.

1)

Disconnect

all

antenna

cables

from

the

set.

(If

they

are

left

connected,

RF

interference

generat-

ed

by

the

computer

will

be

radiated

from

your

supplied

by

SHARP.

*

Part

of

the

image

may

not

be

displayed

on

some

TV

sets,

and

this

is

most

likely

due

to

how

the

ohms,

to

match

the

impedance

of

the

RF

socket

of

your

TV.

*

No

audio

signal

is

output

from

the

RF

socket,

therefore

adjust

the

volume

control

of

the

TV

set

to

minimum.

(2)

Using

the

MZ-1D19

colour

display

unit

1)
