Use only replacement parts that have critical characteristicsrecommended by the manufacturer.2. Make leakage current or resistance me

6、asurements to determine that exposed parts areacceptably 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 corddirectly into a 120V AC

7、outlet. (Do not use an isolation transformer during this test.) Use aleakage current tester or a metering system that complies with American National StandardsInstitute (ANSI) C101.1 Leakage Current for Appliances and Underwriters Laboratories (UL)6500 / IEC 60056 paragraph 9.1.1. With the unit AC s

8、witch first in the ON position and then inOFF position, measure from a known earth ground (metal waterpipe, conduit, etc.) to all ex-posed metal parts of the unit (antennas, handle bracket, metal cabinet, screwheads, metallicoverlays, control shafts, etc.), especially any exposed metal parts that of

9、fer an electrical returnpath to the chassis. Any current measured must not exceed 0.5 milliamp. Reverse the unitpower cord plug in the outlet and repeat test. ANY MEASUREMENTS NOT WITHIN THELIMITS SPECIFIED HEREIN INDICATE A POTENTIAL SHOCK HAZARD THAT MUST BEELIMINATED BEFORE RETURNING THE UNIT TO

10、THE CUSTOMER.B. Insulation Resistance Test Cold Check-(1) Unplug the power supply and connect a jumperwire between the two prongs of the plug. (2) Turn on the power switch of the unit. (3) Measurethe resistance with an ohmmeter between the jumpered AC plug and each exposed metalliccabinet part on th

11、e unit. When testing 3 wire products, the resistance measured to the productenclosure should be between 2 and infinite MOhms. Also, the resistance measured to exposedinput/output connectors should be between 4 and infinite MOhms. When testing 2 wire prod-ucts, the resistance measured to exposed inpu

12、t/output connectors should be between 4 andinfinite 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 L1 Compact system containsno user-serviceable parts.
