OP
I found this about the TP 2.5, but it shows a Rumble switch, so yours might be different, however, you might have some internal settings you can adjust.
Perhaps look at this manual pages 8-12 (manualslib site pages 13-17), you can see and read them online or take screenshots and crop them if you do not want to download something from a site you are unfamiliar with.
