Your CardBot works best when it is regularly updated as updates can range from firmware enhancements to new features and logic improvements.
Luckily, it is very easy to check to see if there are updates:
Go to the Admin Page. You can access this by being on the same network as the CardBot and running the CardBot Connect Tool.
Go to the Settings Tab- on the top right is the 'Check for Updates' section.
If there is an update, there will be a list of updates needed (You will also see a download icon next to the Settings Tab)
Press the button and DO NOT LEAVE THE PAGE- this can corrupt the Bot.
Once the updates are done the page will redirect you to the Admin page.
