Be sure to check for available updates for the product as outdated versions of the software can sometimes cause issues. This will fix bugs and provide the latest features and enhancements. This can be accomplished through the Bose connect app or your computer. After connecting the product to your computer, follow the update instructions on the Bose website.
You may need to reset the product to bring it back to its default factory state. Keep in mind that this will delete all saved settings. To do this:
- Press the power button to turn on the speaker.
- Press and hold the power button for 10 seconds. Wait until you see a blinking blue light coming from the Bluetooth button. You will then hear a voice prompt asking you to select a language.
- Set up the Bluetooth speaker.
If you have replaced the USB cable and the product still does not charge, you may need to replace the AC adapter. AC adapters with a higher current rating generally charge products faster than those with a lower rating. Current ratings are typically listed on the label for the AC adapter in Amps (A) or milliamps (mA). A current rating of 1 A / 1000 mA or higher is recommended. The closer the amp rating of the AC adapter is to the maximum amp rating of the product, the more quickly the product will recharge.
Refer to the specifications indicated on the product or within its owner’s guide for details. Be sure to use a safety-agency-approved AC adapter that meets local regulatory requirements (e.g. UL, CSA, VDE, CCC).
After exhausting all other methods, you may need to replace your product’s battery. With prolonged use, lithium ion batteries deplete their function overtime. The normal charging power for a lithium ion battery is about 300-500 charging cycles. To avoid future problems, be sure to purchase a genuine replacement battery.
