with original Firewire charging
2004-2008
This Service Manual applies to original SoundDock systems built before 8/8/08, DOM 8221. For SoundDock systems built after 8/8/08, use the new SoundDock manual with “USB iPod Charging” part number 277378-SM_USB.
To determine the SoundDock version, use the date of manufacture (DOM) encoded within the serial number located
on the product label
Serial Number example 0402509
Characters 8 to 11 identifiy the DOM - 7342
7342 = the 342nd day of 2007
Both products share the same name and most of the same mechanical assemblies. However, the electronics are
not interchangeable.

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.) 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)
UL6500 / UL60065 / IEC 60065 paragraph 9.1.1. With the unit powered on, measure from a
known earth ground (metal water pipe, conduit, etc.) to all exposed metal parts of the unit
(antennas, handle bracket, metal cabinet, screw heads, 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 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.
CAUTION: The Bose® SoundDock® Digital Music System contains
no user-serviceable parts. To prevent warranty infractions,
refer servicing to warranty service stations or factory service.

USB UPDATE PROCEDURE
The SoundDock Digital Music System changed
the way it charges the iPod in October of 2008.
The system now charges via the USB charge
pins on the iPod.
This change was based on information received
from Apple describing a change to the iPod
charge circuit. iPods manufactured before 8/08
have the ability to charge via Firewire and USB,
some new iPods introduced in November of
2008 will not support the Firewire charge circuit.
It is possible to upgrade SoundDock systems
built before 8/08 from Firewire to USB charging
by replacing the Dock and DSP boards with the
upgraded versions. Use this procedure to upgrade older systems to USB charging.
Equipment Required
a. DSP board / Cradle Assy -
