Product does not power on with battery power

If you are unable to turn on your product while it is unplugged and using only battery power, try the following:

If your product has been in extreme hot or cold temperature, wait until it reaches room temperature.

If the battery temperature is beyond the operating temperature range, wait until the product reaches room temperature, then try again.

Battery protection mode

When your speaker battery is depleted (0%), or your speaker is unplugged and unused for more than three days (with a remaining charge of less than 10%), it enters battery protection mode.

To reactivate your speaker, connect it to a wall charger or computer that is powered on. When not in use, store your speaker in a cool place.

CAUTION: Do not store your speaker for extended periods when fully charged or with a remaining charge of less than 10 percent.

Check if the battery is charged.

Be sure the battery is not depleted. For more information, see Checking the remaining battery charge.

Check if a tone is heard from you product when power is connected.

Disconnect the power connection from your product for a few seconds, then reconnect it. Within a few seconds of connecting power, a tone should play from your product. If a tone is heard but your product won't power on, the issue might be with the connections or controls; if a tone is not heard, the product might not be receiving power or producing sound.

Check for and install any available product updates.

Regardless of the issue you are experiencing with your product, try updating it. Visit btu.Bose.com and follow the instructions to ensure your product has the latest features and enhancements.
