We recommend the following precautions when repairing, replacing or transporting ESDS devices: Perform work at an electrically grounded work station. Wear wrist straps th

9、at 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 unprotec

10、ted devices into materials such as plastic, polystyrene foam, clear plastic bags, bubble wrap or plastic trays. The Bose Model 2150 amplifier is covered by a five-year, transferable, limited warranty. WARRANTY 1. Parts that have special safety characteristics are identified by the symbol on schemati

11、cs 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 th

12、e 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 leak- age current tester or a metering system tha

13、t 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 wate

14、rpipe, conduit, etc.) to all ex- posed 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. Re

15、verse 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

16、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 shou

17、ld 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

18、 specified, there is the possibility of a shock hazard, and the unit must be repaired and rechecked before it is returned to the customer.

Units built after that date have a different version of the

34、amplifiier PCB assembly. Units built before June 2005 use amplifier bare board part number 6000.0435. Units built after that date use bare board part number 8005.0587. The amplifier driver modules for these boards are different as well. The original version used the black TAO103 module. Newer versio

35、ns use a PCB assembly with a heatsink visible on the top of the board. See below. CAUTION: The driver modules and the amplifier boards used with them are NOT compatible with the other versions. Any attempts to use an incorrect driver module on an incompatible amplifier board will result in damage to

36、 both. Be sure to use the appropriate schematic, board layout diagram and parts list for the amplifier PCB assembly in your unit.
