Precautions

The

contains

special

hardware

many

circuits

and

components

specially

for

safety

purposes.

For

continued

protection,

no

changes

should

be

made

to

design

unless

authorized

in

writing

by

the

manufacturer.

Replacement

parts

must

be

identical

to

those

used

in

the

original

circuits.

Service

should

be

performed

by

qualified

personnel

only.

.

Alterations

of

the

design

or

circuitry

of

the

product

should

not

be

made.

Any

design

alterations

of

the

product

should

not

be

made.

Any

design

alterations

or

additions

will

void

the

manufacture's

warranty

and

will

further

relieve

the

manufacture

of

responsibility

for

personal

injury

or

property

damage

resulting

therefrom.

.

Many

electrical

and

mechanical

parts

in

the

product

have

special

safety

~

These

characteristics

are

often

not

evident

from

visual

inspection

nor

can

the

protection

afforded

by

them

necessarily

be

obtained

by

using

replacement

components

rated

for

higher

voltage,

wattage,

etc.

Replacement

parts

which

have

these

special

safety

characteristics

are

identified

in

the

manual.

Electrical

period

of

time,

disconnect

the

power

cord from

the

with

wet

hands.

When

unplugging

from
