Safety
Precautios
1
.
The
design
this
product
contains
special
hardware and
many
circuits
and
components
specially
for
safety
purposes
.
For
continued
protection
,
no
changes
should be made
to
the
original 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
.
2
.
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
.
3
.
Many
electrical and
mechanical
parts
in
the
product
have
special
safety
—
related
characteristics
.
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
parts
list
of
service manual
.
Electrical
components
having
such
features
are
identified
by
shading
and
(
A
\
)
on
the
schematic
diagram
and
by
( )
on
the
parts
list
in
the
service manual
.
The
use
of
a
substitute
replacement
which
does
not
have the
same
safety
characteristics
as
the
recommended
replacement
part
shown
in
the
parts
list
of
service
manual
may
create
shock
,
fire
,
or
other hazards
.
4
.
The
leads
in
the
products
are
routed and dressed
with
ties
,
clamps
,
tubings
,
barriers
and the like
to
be
separated
from
live
parts
,
high
temperature
parts
,
moving
parts
and
or
sharp
edges
for
the
prevention
of
electric shock and
fire
hazard
.
When service
is
required
,
the
original
lead
routing
and dress
should
be observed
,
and
it
should be
confirmed
that
they
have been
returned
to
normal
,
after
reassembling
.
5
.
Leakage
current
check
(
Electrical
shock
hazard
testing
)
After
re
—
assembling
the
product
,
always
perform
an
isolation check
on
the
exposed
metal
parts
of
the
product
(
antenna
terminals
,
knobs
,
metal cabinet
,
screw
heads
,
headphone
jack
,
control
shafts
,
etc
.
)
to
be
sure
the
product
is
safe
to
operate
without
danger
of
electrical
shock
.
Do
not
use a
line isolation
transformer
during
this check
.
•
Plug
the
AC
line
cord
directly
into the
AC
outlet
,
using
aTeakage
current
tester
"
,
measure
the
leakage
current
from
each
exposed
metal
part
of
the cabinet
,
particulary
any
exposed
metal
part
having
a
return
path
to
the chassis
,
to
a
known
good

Now
,
reverse

extension
When

which contains

is recorded
,
these
high
-
frequency
signals
have the
same
function
as
bias and
therefore
,
the
effective

current
changes
.
This
will
result
in
phenomena
such
as
changes
in

signal
and
subsequent
distortion and
reduction
of
the

Dolby

controls the bias
current
so
that the
effective
bias
is
constant
even
when there
are
fluctuations
in
the
high

frequency
components
of
the

This
greatly
improves

the

contain
cracking
noise and
will

If

because
the

the

If

the level is

It

the maximum

The

MAINTENANCE
The
importance
of
cleaning
When the
tape
is
moving
,
magnetic
powder
and
dust
naturally
accumulate
on
the heads
,
capstan
and
pinch
roller
.
When
they
become
too
dirty
:
•
tone
quality
deteriorates
.
•
the
output
sound level
drops
.
•
the
previous
sound is
not
erased
satisfactorily
.
•
recordings
are
not
satisfactory
.
Because
of
this
,
clean
the
heads
,
etc
.
every
10
hours
of
use so
that
optimum
recordings
will
be
made
.
Demagnetizing
the heads
Magnetic objects brought
close
to
the head
or
using
the
deck
for
a
long
period
of
time results
in
magnetization
of
the head
,
thus noise
occurs
.
When the
noise is excessive
,
high
frequen
-
cies
on
the
recorded
tape
may
be erased
.
Demagnetize
the heads and other metal
parts
that
come
into
contact
with
the
tape
every
20
-
30
hours
of
use
with
a head
demagnetizer
(
available
from
your
audio
store
)
.
Cleaning
the heads
,
pinch
roller and
capstan
Wipe
the heads
,
the
capstan
,
etc
.
with
a
cotton
swab
with
its
tip
dipped
In
alcohol
.
For
effective
cleaning
,
use
a
cleaning
kit
available
from
your
audio
store
.
After
cleaning
,
be
sure
that
the
cleaning
fluid
has
completely
dried
before
loading
a
cassette
.
