Should you wish to change your phone for another Android phone, simply log out of your marshcoding.com account on your current phone and uninstall the Marsh 241D app. Once you have installed the Marsh 241D app on your new Android phone, the first time to try to connect to a coder, you will be prompted on your new phone to pair it to your Marsh 241D Coder, and once paired, you will be able to connect and control your coder with the App on your new phone.
