©2008 Bose Corporation Reference Number 277378-SM Rev. 12 Service Manual SoundDock® Digital Music System with original Firewire charging 2004-2008 Electronic Copy Only This Service Manual applies to original SoundDock systems built before 8/8/08, DOM 8221. For SoundDock sys- tems 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 73420105AE 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 cur-
rent 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 prod-
ucts, 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.

5 PRODUCT DESCRIPTION SoundDock®is a powered acoustic package for current and future versions of Apple’s iPod portable MP3 player. It takes the design form of a “picture frame” - a rectangular speaker package that allows the iPod to dock into the middle. SoundDock with docked iPod is an elegant, highly functional, and great-sounding system for use in the living room, kitchen, or bedroom. Bose ® developed and manu- factured the product with input from Apple. Apple and Bose will advertise and sell the product. There are 4 adapters shipped with the product.

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
® SoundDock® Digital Music System is covered by a limited 1-year transferable warranty.

7 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 up- grade older systems to USB charging. Equipment Required a. DSP board / Cradle Assy - Black - 279103-008 White - 279103-010 b. Phillips-head screw driver c. Bose Logo Black - 277381-002 White - 277381-001 1. Original Dock Removal 1.1 Remove the four Phillips-head screws securing the bottom cradle cover. 1.2 Remove cable connected to J300.2. Grille and Amplifier board Removal 2.1 Remove the grille by pushing upward as shown above. 2.2 Remove the four Phillips-head screws securing the amp board to the acoustic enclosure. 3. Install the DSP/Cradle Upgrade Assembly 3.2 Connect the flex cable to J300 on the new upgrade assembly and install the cradle along with the amplifier board. 3.3 Install Bose logo on the front of the cradle. 3.4Fully test with iPod to confirm correct operation.
8 NEW IPOD CHARGING CIRCUIT The original SoundDock® Digital Music System charges the iPod with the Firewire connection pins on the dock assembly. Pin 11 of the Dock connector is used to charge the iPod Battery and pin 13 is used to detect the iPod is placed on the cradle.
