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 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 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® 321 Series II Home Entertainment System
contains no user-serviceable parts. To prevent warranty infractions,
refer servicing to warranty service stations or factory service.

PRODUCT DESCRIPTION
The 3•2•1 Series II Home Entertainment System is the replacement for the 3•2•1 and 3•2•1GS Series I Home Entertainment Systems. It uses the same system concept of a console with a dedicated bass module with TrueSpace arrays.
The console will play video DVDs, DVD-R and DVD+R discs, audio CDs, Video CDs, CD-R and CD-RWs, and MP3 CDs. MP3 disc tracks must be burned in a single closed session. The MP3 disc format must be ISO9660 and each file must have an “.mp3” extension and have no other periods in the filename.
The bass module electronics house some signal processing, power supplies and amplification for the console. The console and bass module are not compatible with the 3•2•1 Series I con­sole and bass module. They cannot be used to replace the other Series components. The speaker arrays are the same as currently used on the 3•2•1 and 3•2•1GS systems. The system includes an enhanced universal type IR remote control similar to that used on the 3•2•1GS Series I system. The remote is non-repairable.
The 3•2•1 Series II uses standard 3•2•1 arrays with a cloth grille. The arrays are graphite in color. The 3•2•1GS Series II systems use the GemstoneTM arrays in both graphite and silver. The array cable color matches the array color. The console for both 321 and 321GS systems is graphite with a silver front bezel. The bass module is graphite, as is the IR remote control.

ACCESSORIES
The Bose 3•2•1 and 3•2•1GS Series II Home Entertainment Systems shelf speakers are com­patible with Bose mounting accessories, including the UB-20 wall brackets, UFS-20 floor stands and UTS-20 table stands.

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.
