Updating your system

Before you begin

To update your system:

  • If the accessory battery is attached to your system, the system battery charge needs to be 30% or higher. See Checking the battery level. Once charged to 30%, the system can be updated on either battery power or wall power. Wall power is recommended
  • A computer with Internet access is required
  • A USB-A to USB-micro B cable is required

Installing the update

On your computer, open a web browser and go to btu.bose.com. Keep your web browser open throughout this process

Review the Bose Updater terms of use, then click "Accept and Continue" if you'd like to run the updater

Click "Download" to download the updater

If your web browser gives download options, choose "Run." Otherwise, once the file is downloaded, open it and install the updater

Connect a USB cable from the computer to the SERVICE jack on your product

Set the system's power switch to the up/on position

Click "Apply Changes." (Note: If no update is available, the updater shows your product is up to date)

Once the system has been successfully updated, disconnect your product from the computer
