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.) Refer to
UL6500 paragraph 9.1.1. 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) 6500, 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 Meg ohms. Also, the resistance measured to exposed output/
input connectors should be between 4 and infinite Meg ohms. When testing 2 wire products, the
resistance measured to exposed output/input connectors should be between 4 and infinite Meg
ohms. 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.
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.
CAUTION: THE BOSE®PS 28 AND PS 35 POWERED SPEAKERCONTAINS NO USER-SERVICEABLE PARTS. TO PREVENT WARRANTY INFRACTIONS, REFER SERVICING TO
WARRANTY SERVICE STATIONS OR FACTORY SERVICE.

Part List Notes
1. This part is not normally available from customer service. Approval from the Field Service
Manager is required before ordering.
2. The individual parts located on the PCB are listed in the part list.
3. 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.
4. This part is set to the Lifestyle
®
28/38 system equalization. To use this part on a Lifestyle® 18, 35
or 48 system, refer to the instructions located on page 31 for setting the Equalizer using TAP
commands. Except for the Lifestyle® 18 system, in place of using TAP commands to set the EQ,
the customer may use the Bose® AdaptIQTM audio calibration system to customize the EQ to their
room. The Lifestyle® 18 system bass module is set to provide a lower outut to match the single
cubes, which can only be set using TAP commands. The AdaptIQ audio calibration system is
®
shipped with the Lifestyle
18,28,35,38,48 system.
