1. Safety Precautions
.
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.
.
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
—
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
(
Z\
_
)on
the
schematic
diagram
and
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.
.
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,
mpving
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.

Warning
1. This equipment has beer designed and manufactured to meet international safety standards.
2. It is the legal responsibility of the repairer to ensure that these safety standards are maintaintaind.
3. Repairs must be made in accordance with the relevant safety standards.
4. It is essential that safety critical components are replaced by approved parts.
5. If mains voltage selector is provided, check setting for local voltage.
