SAFETY INFORMATION
ELECTROSTATIC DISCHARGE SENSITIVE (ESDS)
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.
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 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 120VAC outlet. (Do not use an isolation transformer during this test.) Use a leak-
age current tester or a metering system that complies with American National Standards Institute
(ANSI) C101.1 "Leakage Current forAppliances" and Underwriters Laboratories (UL) UL6500 /
UL60065 / IEC 60065 paragraph 9.1.1. With the unitAC switch first in the ON position and then in
OFF 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, 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 WITHINTHE LIMITS
SPECIFIEDHEREIN INDICATEAPOTENTIALSHOCK HAZARDTHATMUSTBE 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 jumperedAC 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.

AMPLIFIER/DRIVER BOARD VERSION INFORMATION
Units built before June 2005 have the original version of the amplifier PCB assembly. Units built
after that date have a different version of the 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 versions 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 both. Be sure to use the appropriate schematic, board
layout diagram and parts list for the amplifier PCB assembly in your unit.
Original Version Driver Module, used with
the 6000.0435 Amplifier PCB Newer Version Driver Module, used with the 8005.0587Amplifier PCB
