A Bass Module 700 that keeps disconnecting shows solid dim amber on its lower rear LED each time it drops, and turns solid white when it reconnects. Because the module is wireless to the host soundbar, drops are usually caused by the link (placement, another wireless device), by power, or by the host soundbar rebooting. Bose's reset for the module is to unplug it for 30 seconds and wait 15 seconds for it to reconnect to the soundbar.

Model-specific
What is true of this model and not of its siblings
- The module reset
- Disconnect the module's power cord, wait 30 seconds, reconnect it, then wait 15 seconds for it to reconnect to the control console or soundbar.
- Wireless connection
- The module connects to the soundbar wirelessly, so placement matters more than for a wired subwoofer. Keep it in range of the soundbar, avoid stacking it behind metal or glass, and remember that blinking amber means it is ready to pair while solid dim amber means it has lost the soundbar.
- Resetting several devices
- During a full system reset Bose lists the order: turn off the soundbar, unplug the soundbar, the bass module and both surround receivers if fitted, wait 30 seconds, restore the soundbar first, allow about 30 seconds for it to reboot, then reconnect each accessory and wait 15 seconds for it to link.
Stop boundary
When this stops being a self-service repair
- !If the module drops constantly in every location after a full reset, request service from Bose
