Enter the sensor settings (3) of the sensor you want to update (< or > button next to the sensor).

Select Update Firmware.

Select the latest firmware version (if multiple are available) from the dropdown list (4) and click Update (5).

Proceed with the prompts of the update process.
Once the update has been successfully completed, you should see the Firmware Update Completed information as seen in the following screen. Click Dismiss to exit the firmware updater.
