-Safety Precautions
1. This 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 unless authorized in
writing by the manufacturer. Replacement parts must be identical to those used in the original circuits. Services
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 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
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 shading on the schematics and by (/t\,) 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 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 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.
0 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, particularly any exposed metal part having a return
path to the chassis, to a known good earth ground. Any leakage current must not exceed 0.5mA 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
sensitivity in the following manner. Connect a 1,500 Q10W resistor paralleled by a 0.1 51.1 F AC-type capacitor
between an exposed metal part and a known good earth ground. AC VOLTMETER

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 (h) and ICP (Q) or identified by the (N
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.

4. Fteattach the sub tray (3) while inserting the shaft | Sub tray (4)
into the groove in of the main tray, and at the same
time, putting the shaft n on the U/D cam (L). Then,
move the sub tray (3) toward the sub tray (2) until it
stops.
Sub Tray (3)
REFERENCEzAt this point, the sub tray (3) is on top of
the sub tray (2).
5 Reattach the sub tray (4) while fitting the part 0 to
the ACT.gear (2) on the main tray.
CAUTION: Make sure the part 0 of the sub tray (4)
engages with the ACT. gear (2) correctly
in the center of the main tray.
REFERENCEzAt this point, the sub tray (4) is on top of
the sub tray (3).
6. Fleattach the sub tray (6) and (5) in the same way.
CAUTION: Make sure that the trays are attached to
the correct position and that they can be
moved. To move the sub trays manually,
the sub tray drive motor assembly must
be removed in advance.
