SAFETY INFORMATION

A

		This service manual is intended for qualified service technicians; it is not meant for the casual
		do-it-yourselfer. Qualified technicians have the necessary test equipment and tools, and have been
		trained to properly and safely repair complex products such as those covered by this manual.
		Improperly performed repairs can adversely affect the safety and reliability of the product and may
		void the warranty. If you are not qualified to perform the repair of this product properly and safely, you
		should not risk trying to do so and refer the repair to a qualified service technician.
		WARNING
		This product contains lead in solder and certain electrical parts contain chemicals which are known to the state of California to
B		cause cancer, birth defects or other reproductive harm.
		Health & Safety Code Section 25249.6 – Proposition 65

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 MODÈ LE CANADIEN SEULEMENT)

C

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.

(FOR USA MODEL ONLY)

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

c u r r e n t t e s t e r s u c h a s S i m p s o n M o d e l 2 2 9 - 2 o r

D

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 60 Hz outlet and turn the AC power switch on. Any current measured must not exceed 0.5 mA.

			Reading should
		Leakage	not be above
			0.5 mA
		current
E	Device	tester
	under
	test
	Test all
	exposed metal
	surfaces
	Also test with
	plug reversed
	(Using AC adapter		Earth
	plug as required)		ground

AC Leakage Test

ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL SHOCK HAZARD AND MUST BE CORRECTED 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 characteristics 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 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 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.
