1. SAFETY INFORMATION
1. SAFETY PRECAUTIONS
The following check should be performed for the
continued protection of the customer and service tech-
nician.
LEAKAGE CURRENT CHECK
Measure leakage current to a known earth ground
(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 appli-
ance (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.
Leakage
current
tester
Reading should
not be above
0.5mA
Test all
exposed metal
surfaces
2-wire cord
Also test with
O plug reversed Earth
(Using AC adapter : ground
plug as required)
AC Leakage Test
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.
2.PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in the appliance
have special safety related characteristics. These are often
not evident from visual inspection nor the protection
afforded by them necessarily can be obtained by using
replacement components rated for voltage, wattage, etc.
Replacement parts which have these special safety charac-
teristics are identified in this Service Manual.
Electrical components having such features are identified
by marking with 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, shown in 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 additional copies of, PIONEER
Service Manual may be obtained at a nominal charge from
PIONEER.

R Indication without voltage is 50V except electrolytic capacitor.
3. VOLTAGE, CURRENT:
(V1; Signal voltage at wt W, 82 output (1 kHz)
“5: DC voltage (V) at no input signal Value in( —_) is DC voltage at
rated power.
4. OTHERS:

e
When
ordering
resistors,
first
convert
resistance
values
into
code
form
as
shown
in
the following examples.
Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm
and 47k ohm (tolerance is shown by J = 5%, and K = 10%).
