SAFETY

PRECAUTIONS

(This

“safety

precaution”

is

applied

only

in

U.S.A.)

Before

servicing,

unplug

the

power

cord

to

prevent

an

electric

shock.

When

replacing

parts,

use

only

manufacturer’s

recommended

components

for

safety.

Check

the

condition

of

the

power

cord.

Replace

if

wear

or

damage

is

evident.

After

servicing,

be

sure

to

restore

the

lead

dress,

insulation

barriers,

insulation

papers,

shields,

etc.

Before

returning

the

serviced

equipment

to

the

customer,

be

sure

to

make

the

following

insulation

resistance

test

to

prevent

the

customer

from

being

exposed

to

a

shock

hazard.

hg

ON

INSULATION

RESISTANCE

TEST

1.

Unplug

the

power

cord

and

short

the

two

prongs

of

the

plug

with

a

jumper

wire.

2.

Turn

on

the

power

switch.

3.

Measure

the

resistance

value

with

ohmmeter

between

the

jumpered

AC

plug

and

each

exposed

metal

cabinet

part,

such

as

screwheads

antenna,

control

shafts,

handle

brackets,

etc.

Equipment

with

antenna

terminals

should

read

between

3MQ2

and

5.2MQ2

to

all

exposed

parts.

(Fig.

A)

Equipment

without

antenna

all

exposed

parts.

(Fig.

Note:

Some
