14.10  Firmware Upgrade

14.10.1  Automatic Firmware Update after Onboarding

After you have successfully set up the speakers with the KEF Connect App, you may be 
required to update the firmware if a new version is available. Follow the instructions in 
the KEF Connect App to complete the update process.

14.10.2  Automatic Firmware Check

The speakers check the server every 4 hours if a new firmware update is available. If a 
firmware is available, it will check if the firmware update is compulsory or not.

If a firmware update is compulsory, it will start the update when: 

• The speakers are in standby mode, or

• The Wi-Fi source or Bluetooth source has been idle for 60 minutes.

If a firmware update is not compulsory, it will be carried out when:

• The speakers are in standby mode between 2–3 am, or

• The Wi-Fi source or Bluetooth source has been idle for 60 minutes.

A firmware update will not occur when the speakers are in use.
