SECTION 1
PRECAUTION

1.1 Safety Precautions

(1) This design of this product contains special hardware and
many circuits and components specially for safety purpos-
es. 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. Services should be per-
formed 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 manufacturers 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 products have
special safety»related characteristics. These characteris-
tics are often not evident from visual inspection nor can the
protection afforded by them necessarily be obtained by us-
ing replacement components rated for highervoltage, watt-
age, etc. Replacement parts which have these special
safety characteristics are identified in the Parts List of Ser-
vice Manual. Electrical components having such features
are identified by shading on the schematics and by ( A) on
the Parts List in the Service Manual. The use of a substitute
replacement which does not have the same safety charac-
teristics as the recommended replacement parts 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 reassem-
bling.

(5) Leakage shock hazard testing)

After reassembling the product, always perform an isola-
tion check on the exposed metal parts of the product (an-
tenna 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 parts of the cabinet, particular-
ly any exposed metal part having a return path to the
chassis, to a known good earth ground. Any leakage cur-
rent must not exceed 0.5mA AC (r.m.s.).

. Alternate check method
Plug the AC line cord directly into the AC outlet. Use an
AC voltmeter having, 1,000 ohms per volt or more sensi-
tivity in the following manner. Connect a 1,500 ohm 10W
resistor paralleled by a 0.15 F AC-type capacitor be-
tween an exposed metal part and a known good earth
ground.

Measure the AC voltage across the resistor with the AC
voltmeter.

Move the resistor connection to each exposed metal
part, particularly any exposed metal part having a return

path to the chassis, and measure the AC voltage across
the resistor. Now, reverse the plug in the AC outlet and
repeat each measurement. Voltage measured any must
not exceed 0.75 V AC (r.m.s.). This corresponds to 0.5

mA AC (r.m.s.).

1.2 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 maintained.

(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.

1.3 Caution

Burrs formed during molding may be left over on some parts
of the chassis.

Therefore, pay attention to such burrs in the case of pre-
forming repair of this system.

1.4 Critical parts for safety

In regard with component parts appearing on the silk-screen
printed side (parts side) of the PWB diagrams, the parts that are
printed over with black such as the resistor ( - ), diode ( _)
and ICP ( .) or identified by the "A" mark nearby are critical for
safety. When replacing them, be sure to use the parts of the
same type and rating as specified by the manufacturer. (Except
the JC version)

SAFETY INSTRUCTIONS
SOME DOS AND DON'TS ON THE SAFE USE OF EQUIPMENT"

This equipment has been designed and manufactured to meet international safety standards
but, like any electrical equipment, care must be taken if you are to obtain the best results and
safety is to be assured.

Do read the operating instructions before you attempt to use the equipment.

Do ensure that all electrical connections (including the mains plug, extension leads and
interconnections between pieces of equipment) are properly made and in accordance with the
manufacturer's instructions. Switch off and withdraw the mains plug when making or changing
connections.

Do consult your dealer if you are ever in doubt about the installation, operation or safety of
your equipment.

Do be careful with glass panels or doors on equipment.

DON'T continue to operate the equipment if you are in any doubt about it working normally, or
if it is damaged in any way-switch off, withdraw the mains plug and consult your dealer.

DON'T remove any fixed cover as this may expose dangerous voltages.

DON'T leave equipment switched on when it is unattended unless it is specifically stated that it
is designed for unattended operation or has a standby mode.

Switch off using the switch on the equipment and make sure that your family know how to do
this.

Special arrangements may need to be made for infirm or handicapped people.

DON'T use equipment such as personal stereos or radios so that you are distracted from the
requirements of traffic safety. It is illegal to watch television whilst driving.

DON'T listen to headphones at high volume as such use can permanently damage your
hearing.

DON'T obstruct the ventilation of the equipment, for example with curtains or soft furnishings.
Overheating will cause damage and shorten the life of the equipment.

DON'T use makeshift stands and NEVER fix legs with wood screws - to ensure complete
safety always fit the manufacturers approved stand or legs with the fixings provided according
to the instructions.

DON'T allow electrical equipment to be exposed to rain or moisture.
ABOVE ALL

-NEVER let anyone, especially children, push anything into holes, slots or any other opening in
the case -this could result in a fatal electrical shock.;

-NEVER guess or take chances with electrical equipment of any kind -it is better to be safe than
