8、RY INFORMATION OFBOSE CORPORATION WHICH IS BEING FURNISHED ONLY FOR THE PURPOSE OF SERVICING THE IDENTIFIED BOSE PRODUCT BY AN AUTHORIZED BOSE SERVICE CENTER OR OWNER OF THE BOSE PRODUCT, AND SHALL NOT BE REPRODUCED OR USED FOR ANY OTHER PURPOSE.CAUTION: THE 102 SYSTEM CONTROLLER CONTAINS NO USER-SE

9、RVICEABLE PARTS. TO PREVENT WARRANTY INFRACTIONS, REFER SERVICING TO WARRANTY SERVICE STATIONS OR FACTORY SERVICE.ELECTROSTATIC DISCHARGE SENSITIVE (ESDS)DEVICE HANDLINGThis unit contains ESDS devices. We recommend the following precautions when repairing,replacing, or transporting ESDS devices:Perf

10、orm 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 dev

11、ices in ESD protective bags, bins, or totes. Do not insertunprotected devices into materials such as plastic, polystyrene foam, clear plastic bags, bubblewrap, or plastic trays.4SAFETY INFORMATION1. Parts that have special safety characteristics are identified by the ! symbol on schematics or by spe

12、cial 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. U

13、se the following checks to perform these measurements: A. Leakage Current Hot Check (1) 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 wi

14、th American National Standards Institute (ANSI) C101.1 Leakage Current for Appliances and Underwriters Laboratories (UL) 1492 (71). (2) With the unit AC switch first in the ON position and then in the OFF position, measure from a known earth ground (metal water pipe, conduit, etc.) to all exposed me

15、tal 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. (3) Any current measured must not exceed 0.5 milliamp. (4) Reverse the unit power cord plug in

16、 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 pro

17、ngs 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 the exposed metallic part has a return path to the chassis, the reading should be between 1 and 5.2 megohms. Wh

18、en there is no return path to the chassis, the reading must be infinite. 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.5SPECIFICATIONS102 System Controller:Input Level:Music - 10
