SAFETY INFORMATION

1. Parts that have special safety characteristics are identified by the symbol on schematics

or by special notes on the parts list. Use only replacement parts that have critical characteristics recommended by the manufacturer.

2. Make leakage current or resistance measurements to determine that exposed parts are acceptably insulated from the supply circuit before returning the unit to the customer. Use the following checks to perform these measurements:

A. Leakage Current Hot Check - With the unit completely reassembled, plug the AC line cord directly into a 120V AC outlet. (Do not use an isolation transformer during this test.) Use a leakage current tester or a metering system that complies with American National Standards Institute (ANSI) C101.1 "Leakage Current for Appliances" and Underwriters Laboratories (UL) UL6500 / UL60065 / IEC 60065 paragraph 9.1.1. With the unit AC switch first in the ON position and then in OFF position, measure from a known earth ground (metal waterpipe, conduit, etc.) to all exposed metal parts of the unit (antennas, handle bracket, metal cabinet, screwheads, metallic overlays, control shafts, etc.), especially any exposed metal parts that offer an electrical return path to the chassis. Any current measured must not exceed 0.5 milliamp. Reverse the unit power cord plug in the outlet and repeat test. ANY MEASUREMENTS NOT WITHIN THE LIMITS SPECIFIED HEREIN INDICATE A POTENTIAL SHOCK HAZARD THAT MUST BE ELIMINATED BEFORE RETURNING THE UNIT TO THE CUSTOMER.

B. Insulation Resistance Test Cold Check - (1) Unplug the power supply and connect a jumper wire between the two prongs of the plug. (2) Turn on the power switch of the unit. (3) Measure the resistance with an ohmmeter between the jumpered AC plug and each exposed metallic cabinet part on the unit. When testing 3 wire products, the resistance measured to the product enclosure should be between 2 and infinite MOhms. Also, the resistance measured to exposed input/output connectors should be between 4 and infinite MOhms. When testing 2 wire products, the resistance measured to exposed input/output connectors should be between 4 and infinite MOhms. If it is not within the limits specified, there is the possibility of a shock hazard, and the unit must be repaired and rechecked before it is returned to the customer.

CAUTION: The Bose® Panaray® 502® Sound System contains

no user-serviceable parts. To prevent warranty infractions,

refer servicing to warranty service stations or factory service.

DEVICE HANDLING

This unit contains ESDS devices. We recommend the following precautions when repairing, replacing or transporting ESDS devices:

• Perform work at an electrically grounded work station.

• Wear wrist straps that connect to the station or heel straps that connect to conductive

floor mats.

• Avoid touching the leads or contacts of ESDS devices or PC boards even if properly grounded. Handle boards by the edges only.

• Transport or store ESDS devices in ESD protective bags, bins, or totes. Do not insert unprotected devices into materials such as plastic, polystyrene foam, clear plastic bags, bubble wrap or plastic trays.

PARTS LIST NOTES

1. This part is not normally available from Customer Service. Approval from the Field Service

Manager is required before ordering.

2. This part splits into 2 pieces. Each piece fits onto a corner of the bass box.

3. Current European units should contain 2 owner's manuals: the original version, P/N 143585,

and the German version of the owner's manual, P/N 171941. Future production units (except in North America) will contain owner's manuals in 5 languages (German, French, Italian, Spanish and English).

4. This illustration is typical of the internal layout of the 502® except as follows: (1) Barrier strip connectors are used in the US/Canada version only. XLR connectors are used on all non-US versions, and (2) The nut connected to the line cord is used on the US/Canada, UK and Australian units only.

5. This part is critical for safety purposes. Failure to use a substitute replacement with the same safety characteristics as the recommended replacement part might create shock, fire and/ or other hazards.

6. Refer to the 502C Electrical Parts List for components located on the PCB assembly.

7. This part is not illustrated.

8. These screws hold regulators U13 and U14 to the heatsink.

9. Early production runs of the 502C have 4 screws (instead of 2) that secure the cover to the

chassis.

10. Early production runs of the 502C with XLR connectors have 12 screws (instead of 6) that secure the connectors to the chassis.

11. Early production runs of the 502C have 6 screws (instead of 4) that secure the front plate to the cover and chassis.

12. Early production runs of the 502C with XLR connectors have 5 screws (instead of 2) that secure the PCB to the chassis.

13. The line cord assembly consists of the following items: (1) Line Cord-P/N 147428 (US/Canada), P/N 147430 (Euro), P/N 147429 (Japan), P/N 149025 (UK), P/N 149026 (Aus.), (2) Strain Relief Bushing - P/N 144010 (US/Canada/UK/Aus), P/N 144011 (Euro/Japan), (3) Connector Housing - P/N143964, and (4) Connector Pin - P/N 143992.
