Troubleshooting

Guide

Although

the

greatest

care

has

been

taken

in

the

manufacture

of

this

unit,

the

possibility

remains

that

a

fault

could

appear

or

that

for

some

reasons

the

unit

could

fail

to

function

to

your

complete

satisfaction.

The

cause,

however,

will

not

always

be

found

in

the

unit

itself.

External

factors,

and

the

fact

that

it

takes

time

to

become

accustomed

to

the

whole

concept

of

the

new

product

and

the

new

discs,

can

also

play

a

role.

To

save

your

unnecessary

calls

on

your

dealer

or

our

Service

Organization,

we

have

compiled

a

list

of

possible

faults

and

their

causes.

To

even

mention

some

of

these

causes,

such

as

those

to

do

with

power

connection,

may

perhaps

seem

excessive.

Our

experience

shows,

however,

that

they

are

easily

overlooked

as

sources

of

troubles.

If,

by

using

this

list,

you

do

not

succeed

in

solving

the

problem,

stop

your

investigation.

Disconnect

the

AC

cord

and

contact

your

dealer.

Under

no

circumstances

should

you

open

up

the

unit.

If

you

should,

this

will

invalidate

all

your

rights

under

the

guarantee.

NOTE:

If

the

faults

relating

to

the

power

or

the

connections

arise

when

the

unit

is

a

part

of

a

system,

check

your

operating

instructions

for

the

amplifier

of

the

system.
