NOTICE

(FOR CANADIAN MODEL ONLY)

Fuse symbols

(fast operating fuse)

and/or

(slow operating fuse) on PCB indicate that replacement

parts must be of identical designation.

REMARQUE

(POUR MODÈLE CANADIEN SEULEMENT)

Les symboles de fusible

(fusible de type rapide)

et/ou

(fusible de type lent) sur CCI indiquent que

les pièces de remplacement doivent avoir la même désignation.

ANY MEASUREMENTS NOT WITHIN THE

LIMITS OUTLINED ABOVE ARE INDICATIVE

OF A POTENTIAL SHOCK HAZARD AND

MUST BE CORRECTED BEFORE RETURN-

ING THE APPLIANCE TO THE CUSTOMER.

2. PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in the appliance

have special safety related character istics. 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 par ts which have these

special safety character istics are identified in this

Service Manual.

Electr ical 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

does 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

infor mation, always consult the current PIONEER

Ser vice Manual. A subscription to, or

additional copies

of, PIONEER Ser vice Manual may be obtained at a

nominal charge from PIONEER.

(FOR USA MODEL ONLY)

1. SAFETY PRECAUTIONS

The following check should be perfor med for the

continued protection of the customer and ser vice

technician.

LEAKAGE CURRENT CHECK

Measure leakage current to a known ear th ground

(water pipe, conduit, etc.) by connecting a leakage

current tester such as Simpson Model 229-2 or

equivalent between the ear th ground and all exposed

metal par ts of the appliance (input/output ter minals,

screwheads, metal overlays, control shaft, etc.). Plug

the AC line cord of the appliance directly into a 120V

AC 60 Hz outlet and turn the AC power switch on. Any

current measured must not exceed 0.5 mA.

Device
