Start with the switch on--the board will enter into setup mode, displaying the wifi access point name and password, as well as the address. Connect to this wifi, enter the name of the wifi that the stock ticker should be using, the password, and the stock ticker symbol you want to track. Submit the changes and turn off the switch. Restart the ticker by removing the power and reconnecting it.
