Triumph tracer

HELP!!!! I need to get into the Triumph Tracers Communications screen and change the baud Rate to work with my edger. It seems there's a combination of buttons that needs to be mashed while the machine is turned on. My source is telling me its the 2nd and 5th buttons but that isn't working. Of the 10 lil black buttons, only the first one being mashed brings me to another screen, the Diagnostic screen.
I know the tracer older but it works and looks new, please help so that I may use it! Thank you!!!!!
