Please heed the points listed below during servicing and inspection.
Heed the cautions!
Spots requiring particular attention when servicing, such
as the cabinet, parts, chassis, etc., have cautions indicated
on labels or seals. Be sure to heed these cautions and the
cautions indicated in the handling instructions.
Caution concerning electric shock!
(1) An AC voltage is impressed on this set, so touching in-
ternal metal parts when the set is energized could
cause electric shock. Take care to avoid electric shock,
by for example using an isolating transformer and
gloves when servicing while the set is energized, un-
plugging the power cord when replacing parts, etc.
(2)There are high voltage parts inside. Handle with extra
care when the set is energized.
Caution concerning disassembly and
assembly!
Though great care is taken when manufacturing parts from
sheet metal, there may in some rare cases be burrs on the
edges of parts which could cause injury if fingers are
moved across them. Use gloves to protect your hands.
Only use designated parts!
The set's parts have specific safety properties (fire resis-
tance, voltage resistance, etc.). For replacement parts, be
sure to use parts which have the same properties. In par-
ticular, for the important safety parts that are marked z on
wiring diagrams and parts lists, be sure to use the desig-
nated parts.
Be sure to mount parts and arrange
the wires as they were originally!
For safety reasons, some parts use tape, tubes or other in-
sulating materials, and some parts are mounted away from
the surface of printed circuit boards. Care is also taken with
the positions of the wires inside and clamps are used to
keep wires away from heating and high voltage parts, so
be sure to set everything back as it was originally.
Inspect for safety after servicing!
Check that all screws, parts and wires removed or discon-
nected for servicing have been put back in their original po-
sitions, inspect that no parts around the area that has been
serviced have been negatively affected, conduct an insu-
lation check on the external metal connectors and between
the blades of the power plug, and otherwise check that
safety is ensured.
(Insulation check procedure)
Unplug the power cord from the power outlet, disconnect
the antenna, plugs, etc., and turn the power switch on. Us-
ing a 500V insulation resistance tester, check that the in-
sulation resistance between the terminals of the power
plug and the externally exposed metal parts (antenna ter-
minal, headphones terminal, microphone terminal, input
terminal, etc.) is 1M or greater. If it is less, the set must
be inspected and repaired.
Concerning important safety
parts
Many of the electric and structural parts used in the set
have special safety properties. In most cases these prop-
erties are difficult to distinguish by sight, and using re-
placement parts with higher ratings (rated power and
withstand voltage) does not necessarily guarantee that
safety performance will be preserved. Parts with safety
properties are indicated as shown below on the wiring dia-
grams and parts lists is this service manual. Be sure to re-
place them with parts with the designated part number.
(1) Schematic diagrams ... Indicated by the z mark.
(2) Parts lists ... Indicated by the z mark.
Using parts other than the designated
parts could result in electric shock, fires or
other dangerous situations.
SAFETY PRECAUTIONS
The following check should be performed for the continued protection of the customer and service technician.
LEAKAGE CURRENT CHECK
Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis
resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the
power cord is less than 460 kohms, the unit is defective.

NOTE FOR PARTS LIST
• Parts for which "nsp" is indicated on this table cannot be supplied.
• When ordering of part, clearly indicate "1" and "I" (i) to avoid mis-
supplying.
• Ordering part without stating its part number can not be supplied.
• Part indicated with the mark " " is not illustrated in the exploded view.
• Not including General-purpose Carbon Film Resistor in the P.W.Board
parts list. (Refer to the Schematic Diagram for those parts.)
• Not including General-purpose Carbon Chip Resistor in the P.W.Board
parts list. (Refer to the Schematic Diagram for those parts.)
WARNING:
Parts marked with this symbol z have critical characteristics.
Use ONLY replacement parts recommended by the manufacturer.
