The Bass Module 700 does not pair like a Bluetooth speaker; it links to its host soundbar wirelessly, and its rear LED shows the state: blinking amber means ready to pair, solid dim amber means disconnected from the soundbar, and solid white means connected. In the Bose app's Smart Soundbar 600 setup, tapping Connect for an accessory bass module or surround speakers starts the link. If the module stays amber, unplug it for 30 seconds, reconnect it and wait 15 seconds for it to find the soundbar.

Model-specific
What is true of this model and not of its siblings
- Connecting in the app
- During Smart Soundbar 600 setup the Bose app offers a Connect option for an accessory bass module or surround speakers; choosing Do It Later skips that step and it can be done afterwards.
Stop boundary
When this stops being a self-service repair
- !If the LED shows any state other than the listed ones, Bose says the module requires service, so contact Bose Support
- !If the module never leaves blinking amber after a full reset of both devices, request service
