Mcs 2000 button assignment and rssi

[spectra]

Hi hoping someone can help to explain a few questions regarding an mcs2000 with the type two head.
In the cps their are options to assign the buttons on the head but changing them has no effect.
Also curious about rssi function i can't find any button assignment info or anything related to enabling it in the cps.
I.d no M01RLM9PW6PM
And CPS 2.03.00
I am using an aftermarket rib with the rj45 connector as well.
