SAFETY

PRECAUTIONS

WARNING

Before

servicing

this

unit,

familiarize

yourself

with

the

following

precautions:

1

.

Many

electrical

and

mechanical

parts

in

this

chassis

have

special

safety

characteristics

that

often

pass

unnoticed

and

the

protection

afforded

by

them

cannot

necessarily

be

obtained

by

using

replacement

components

rated

for

higher

voltage,

wattage,

etc.

Replacement

parts

that

have

these-special

safety

characteristics

are

identified

in

this

manual

and

its

supplements:

electrical

components

having

such

features

are

identified

by

/\

in

the

schematic

diagram

and

the

parts

list.

Before

replacing

any

of

these

components,

read

the

parts

list

in

this

manual

carefully.

The

use

of

substitute

replacement

parts

that

do

not

have

the

same

safety

characteristics

as

specified

in

the

parts

list

may

create

shock,

fire,

or

other

hazards.

.

Before

returning

the

set

to

the

customer,

always

do

an

AC

leakage

current

check

on

the

exposed

metal

parts

of

the

cabinet,

such

as

terminals,

screw

heads,

and

metal

overlays,

to

be

sure

the

set

is

safe

to

operate

danger

of

electrical

shock.

Plug

the

AC

line

cord

directly

into

a

120

V

AC

outlet(USA

Version)

or

230

V

AC

outlet(EU

Version).

(Do.

not

use

a

line

isolation

transformer

during

this

check.)

Be

sure

your

AC

voltmeter

has

a

sensitivity

of

5000

Q

per

volt

or

greater.

Then

connect

a

1500

Q

10

watt

resistor,

paralleled

by

a

0.15

pF

150

V

AC

capacitor,

between

a

known

good

earth

ground(such

as

a

water

pipe,

or

conduit)

and

the

exposed

metalic

is

parts,

one

at

a

time.

Measure

the

AC

voltage

across

the

combination

of

a

1500

Q

resistor

and

a

0.15

pF

capacitor.

Reverse

the

AC

plug

at

the

AC

outlet

and

repeat

AC

voltage

measurements

for

each

exposed

metalic

part.

Voltage

measured

must

not

exceed

0.75

V

RMS.

This

corresponds

to

0.2

mA

AC.

Any

value

exceeding

this

limit

constitutes

a

potential

shock

hazard

and

must

be

corrected

immediately.

:

At

5000

Q

per

volt

or

greater

sensitivity,

the

reading

should

not

exceed

0.75

V.
