1. Safety Precautions

1. The design this product contains special hardware and many circuits and components spectaliy 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. Arty
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 pans list of
service manual. Electrical components having such features are identified by ( A )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. 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
reassembiing.

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 aLeakage 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 a known good eanh ground. Any
leakage current must not exposeed 0.5mA AC(r.m.s.)

- Alternate check method

h AC l' - l « t, U A l AC VOLTMETER

Plug t e ine cord directy into the AC outle so an C votmeter E33 (Having 1°00 ohms/volt,
having 1.000 ohms per volt or more sensitivity in the following manner. or more sensitivity.)
Connect a 1.500 ohms iow resistor paralleled by a 0.15 [1 F AC type a
capacitor between an exposed metal pan and a known good earth 0-1551F AC TYPE
ground. Measure the AC voltage across the resistor with the AC L

and measure the AC voltage across the resistor. Now. reverse the plug Good 93" WWW

in the AC outlet and repeat each measurement. Any voltage measured

A 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 preformlng repair of this system.

3.Removal of Main Parts

I Removing the rear cover and side
panel (See Figs.3-1~3~4)

1. ' Remove the six screws ® retaining the rear cover
from behind the body.
- From the bottom face of the body, remove the tour
screws (2 retaining the rear cover.
- After passing the lock pawls at the speaker terminals
through the position in Fig. 5- 1, remove the rear
cover.

Rear cover

2. - Remove the two screws (3 retaining both of the right
and left side panels. Speaker
- By moving the side panels (right and left sides) while
pulling out the panels toward the rear side, disengage
the upper two engagement sections, and dismount the
panels while expanding them toward the front side.

356 For assembling (the rear cover and side panels), mount 6)
the upper two engagement sections while aligning the
same in place at first, and assemble the rear cover and
side panels while plugging (the cover and panels)
toward the front side.

3. The side fitting should be pulled out upward.
