Precaution	Description
Power Disconnect	Disconnect AC adapter and remove battery before servicing.
Static Discharge	Use anti-static wrist strap and mat when handling circuit boards.
Battery Handling	Do not puncture, short-circuit, or expose battery to high heat.
Component Handling	Handle connectors and flex cables with care; avoid excessive force.
Work Area	Work in a clean, well-lit area free of moisture and clutter.

Required Tools

Gather the following tools before beginning the repair process.

Torx T6 and T8 screwdrivers.
Phillips #00 screwdriver.
Plastic spudger or opening tool.
Anti-static wrist strap.
Multimeter for electrical testing.
Soft cloth and container for screws.

WARNING! Using incorrect tools may damage screws and housing. Use proper size and type.

Internal Components

Key internal parts: Main PCB, amplifier IC, dock connector assembly, battery management board, speaker drivers (left/right), control button board, LED indicators.

PCB Layout: Main board contains audio DSP, power management, and charging circuitry. Dock connector is soldered to main board via flex cable.

Amplifier: Class-D amplifier IC. Battery: 3.7V Li-ion pack with protection circuit. Speakers: Two full-range drivers with neodymium magnets. Connectors: 30-pin iPod connector (early models), auxiliary input jack.

Common Faults & Diagnostics

No power: Check battery, DC jack, fuse on PCB. No audio: Test amplifier IC, speaker connections, dock connector. Intermittent operation: Inspect ribbon cables, solder joints. Battery not charging: Verify charging circuit, battery health.

Use multimeter to check voltage at battery terminals (should be ~3.7V).
Check DC input for 12V.
Inspect dock connector for bent pins or debris.

Tip: Refer to schematic for voltage test points on main PCB.

Component Replacement

Replacement parts must be genuine Bose or approved equivalents.

Speaker Replacement: Desolder wires, remove mounting screws, install new speaker.
Dock Connector: Desolder old connector, clean pads, solder new connector aligning pins.
Battery: Disconnect old battery, connect new pack observing polarity.
Amplifier IC: Use hot air station for removal; apply new solder paste and reflow.
Buttons: Replace button membrane if unresponsive.
LEDs: SMD LEDs can be replaced with same specification.
Fuse: Replace if blown (check for short circuit first).
Ribbon Cables: Ensure connectors are locked and cables seated fully.

WARNING! Electrostatic discharge can damage ICs. Always use ESD protection.
