1 Safety Precautions

. The design of this product contains special hardware.

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 per-
formed by qualified personnel only.

2. Alterations of the design or circuitry of the product
should not be made. Any design alterations or additions
will void the manufacturer's warranty and will further
relieve the manufacturer 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 charac-
teristics are often not evident from visual inspection
nor can the protection afforded by then 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 (A) on the
schematics and parts list in Service manual. The use of
a substitutue replacement which does not have the same
safety charactensitics as the recommended replacemeM
part shown in the parts list in 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/or the like to be
separated from live parts, high temperature part, mov-
ing parts and/or sharp edges for the prevention of elec-
tric shock and fire hazard.

When service is required, the original lead routing and
dress should be observed, and they should be confirmed
to be returned to normal, after rte-assembling.

5. Leakage current check

(Satety for electrical shock hazard)

After re-assembling the product, always perform an

isolation check on the exposed metal parts of the Pro-

ducts (antenna terminals, knobs, metal cabinet, screw

heads, earphone iack, 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. UsV
ing a Leakage Current Tester", measure the leakage
current from each exposed metal part of the cabinet,
particularly any exposed metal part having a return
path to the chassis, to a known good earth ground
(water pipe, etc,). Any leakage current must not ex-
ceed 0.5 mA 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 mroe
sesitivity in the following manner. Connect a 1500 Q
10 W resistor paralleled by a 0.15 F AC-type capaci-
tor between an exposed metal part and a known good
earth ground (water pipe, etc).
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 volt-
age across the resistor. Now, reverse the plug in the
AC outlet and repeat each measurement. Any voltage
measured musy not exceed 0.75 V AC (r.m.s.).
This corresponds to 0.5 mA AC (r.m.s.).
