1.SAFETY PRECAUTIONS
The following check should be performed for the
continued protection of the customer and service
technician.
LEAKAGE CURRENT CHECK
Measure leakage current to a known earth ground
ANY MEASUREMENTS NOT WITHIN THE LIMITS
OUTLINED ABOVE ARE INDICATIVE OF A PO-
TENTIAL SHOCK HAZARD AND MUST BE COR-
RECTED BEFORE RETURNING THE APPLIANCE TO
THE CUSTOMER.
(water pipe, conduit, etc.) by connecting a leakage
current tester such as Simpson Model 229-2 or
equivalent between the earth ground and all exposed
metal parts of the appliance (input/output terminals,
screwheads, metal overlays, control shaft, etc.). Plug
the AC line cord of the appliance directly into a 120V
AC 60Hz outlet and turn the AC power switch on. Any
current measured must not exceed 0.5mA.
z Reading should
Leakage | 10t be above
0.5mA
Test all
ekposed metal
surfaces
Also test with
plug reversed
(Using AC adapter
plug as required)

2.PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in the appli-
ance have special safety related characteristics. These
are often not evident from visual inspection nor the
protection afforded by them necessarily can be ob-
tained by using replacement components rated for vol-
tage, wattage, etc. Replacement parts which have
these special safety characteristics are identified in
this Service Manual.
Electrical components having such features are
identified by marking witha A on the schematics and
on the parts list in this Service Manual.
The use of a substitute replacement component which
dose not have the same safety characteristics as the
PIONEER recommended replacement one, shownin
the parts list in this Service Manual, may create shock,
fire, or other hazards.
Product Safety is continuously under review and
new instructions are issued from time to time. For
the latest information, always consult the current
PIONEER Service Manual. A subscription to, or ad-
ditional copies of, PIONEER Service Manual may be
obtained at a nominal charge from PIONEER.

NOTE FOR SCHEMATIC DIAGRAMS (Type 4A)
1. When ordering service parts, be sure to refer to
“PARTS LIST of EXPLODED VIEWS” or “PCB
PARTS LIST”.
2. Since these are basic circuits, some parts of them or the
values of some components may be changed for improve-
ment.
3. RESISTORS:
Unit: k:kQ, M:MQ, or Q unless otherwise noted.
Rated power: 1/4W, 1/6W, 1/8W, 1/10W unless otherwise
noted.
Tolerance: (F): +1%, (G): +2%, (K): +10%, (M): +20% or +5% un-
less otherwise noted.
4. CAPACITORS:
Unit: p:pF or uF unless otherwise noted.
Ratings: capacitor (uF)/ voltage (V) unless otherwise noted.
Rated voltage: 50V except for electrolytic capacitors.
5. COILS:
Unit: m:mH or uH unless otherwise noted.
6. VOLTAGE AND CURRENT:
SJ or -.V:
DC voltage (V) in PLAY mode unless otherwise noted.
© mA or> mA:
DC current in PLAY mode unless otherwise noted.
Value in( ) is OC current in STOP mode.
7. OTHERS:
¢@or®@ : Adjusting point.
e : Measurement point.
e The A mark found on some component parts indicates the im-
portance of the safety factor of the parts. Therefore, when re-
placing, be sure to use parts of identical designation.
8. SCH—O] ON THE SCHEMATIC DIAGRAM:
e SCH—O indicates the drawing number of the schematic dia-
gram. (SCH stands for schematic diagram.)
