Safety Precautions

1.

The design of 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 uniess 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 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 characteristics

are often not evident from visüal 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 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 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 conf irmed that they

have been returned to normal, after re-assembling.

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, particularly any exposed metal part having a return path to the
chassis, to a known good earth ground. Any leakage current must not exceed 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
tivity in the following manner. Connect a
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 volt-

age across the resistor. Now, reverse the plug in the

AC outlet and repeat each measurement. Any voltage
measured must not exceed

corresponds to 0.5 mA AC (r.m.s.). „ ^ ,_

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.

Notes:

1.

Disconnect the power cord when connect-

ing any component.

2.

Connect to an amplifier with left and right

channels connected correctly. Reversed

channels will degrade the stereo effect.

3. Connect plugs or wires firmly. Poor con-

tact may result in hum.

4.

In case of using the external AM antenna,

be sure to connect a ground wire to the

GND terminal to obtain AM signals with

less noise.

AM Antenna
How to fix the loop antenna (FIg. 1)

• Install the antenna by inserting it in the direc­tion of the arrow. (see Fig. 6)

• Place at a distance trom the power-source
cord,

signal cord and metal fixtures on the main

body. in a spot where reception is good.

AM (MW/LW) loop antenna (Fig. 2)

This antenna is tor the reception of local AM broad­cast. (See Fig, 7)

AM (MW/LW) external antenna (Fig. 2)

If AM reception is unsatisfactory, connect an ex­ternal AM antenna (single-wire antenna) to the AM
antenna terminal.

Noise and interference (FIg. 3)

Change the direction of the loop antenna or

stall it in a better position when reception is noisy.

Notes:

• If the provided loop antenna is not con­nected,

it wil! be impossible to receive AM

broadcasts.

• When installing an external AM antenna,
leave the AM loop antenna connected.

1.

Open the claws at both sidesand remove the

cover.

2.

Cut both ends of the oord and remove it. (only

when using coaxial cable)

3. FIX the coaxial cable and lts core.

4.

Put on the cover.

In case of a 300-ohm antenna (Fig. 9)

It is not necessary to remove the cover. If the wire
inside is cut, 300 ohm antenna can not be used.

Notes:

• Choose antennas to meet the reception
conditions.

• Oriënt and fix antennas where audio
