When Cook-Key ® is attached to Thermomix ® TM5, an automatic check for the latest software is already on your Thermomix ® TM5. If there is a new update available you will get a notification on your Thermomix ® TM5 display where you can confirm the software update. Please note that the update of the software might take a few minutes.
If it does not happen automatically, you can check for updates by going to HELP > ABOUT THERMOMIX® > CHECK FOR UPDATES
