Activate or reset trip B?

Sounds like a simple task however, I cannot locate a trip b to activate and/or reset. I know how to access the TFT menu ect., but I cannot figure out how to access Trip B. Looking through the owners manual I see there is a trip b and it indicates that it may need to be activated. I assume that it is not active by default because I cannot access it but I don't know for sure. Anyone deal with this issue? Thanks in advance for any information you can provide.
