2.

This

product

must

be

grounded.

If

it

should

malfunction

or

breakdown,

grounding

provides

a

path

of

least

resistance

for

electric

current

to

reduce

the

risk

of

electric

shock.

This

product

is

equipped

with

a

power

supply

cord

having

an

equipment-grounding

conductor

and

a

grounding

plug.

The

Improper

connection

of

the

equipment-grounding

conductor

can

result

in

a

risk

of

electric

shock.

Do

not

modify

the

plug

provided

with

the

product

-

if

it

will

not

as

to

whether

the

product

is

properly

grounded,

check

with

a

qualified

serviceman

Digital

that

always

this

than

the

therefore

digital

unattainable

by

Digital

SETUP

AND

OPERATIONAL

CHECKOUT

VOLTAGE

SELECTION

The

K2000

is

equipped

with

a

voltage

selector

which

allows

operation

on

single-phase

AC

of

100

Volts,

120

Volts,

220

Volts,

or

240

Volts.

The

selector

is

set

at

the

factory

for

the

AC

line

voltage

most

commonly

in

the

country

of

destination.

The

setting

can

be

checked

by

looking

at

the

small

panel

just

to

the

left

of

the

AC

power

connector

- a

white

indicator

is

visible

in

the

hole

the

selected

voltage.

Do not attempt to operate the K2000 on any AC voltage other than the one selected -extensive

damage to the unit

may

result!

There

are

two

banks

of

SIMM

sockets,

the

two

inner

install

the

SIMMs

in
