1. Safety Precautions
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(
/\
_)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.
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,
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.
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 a"Leakage 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

Warning
1. This equipment has been 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.

secondary terminal on the print circuit board to provide
proper creeping and spatial distance, solder must not
protrude from soldering round.
@ The tab for winding the power cord must be twisted and

6. Any wire, etc. should be clamped or bonded as indicated in
the above diagram so that such wire will not be positioned
close to any exothermic parts.
7. Wires must be clamped or secured at the locations shown in
the figure so that the wire do not touch to live parts mowing
part, hot part, or sharp edges.
8. By using the special tool , attach the power cord bushing to
the position where “4N — 4” is marked.

Using the remote control unit
To use the remote control unit, point it at the REMOTE
SENSOR and press the buttons gently and firmly. Remote
control operation is possible within about 7 m (approx. 23
ft). However, since the remote control range Is less when
the unit is used at an angle, use directly in front of the
REMOTE SENSOR, as far much possible.
Do not expose the REMOTE SENSOR to strong light (direct
sunlight or artificial lighting) and make sure that there are
no obstacles between the REMOTE SENSOR and the
semote control unit.
