I have a C965 display for my Bafang BBS01. I cannot find how to set the wheel dimension on the thing.

The documentation I found online says that I can enter a settings menu by double press on the power button. This does nothing but if I press the plus and minus buttons together I get to some kind of settings menu but not the same one as in the manual.

When I click the plus and minus buttons together I get these menus that I can rotate through by pressing the power button:

tC - with y/n options , anyone know what tC is used for? What does it set?
bL - back light I presume
S7 - sets km or mph
OFF - auto time off.

So nothing to do with wheel diameter.
I am also expecting speed limit, password, and voltage settings but cannot find these either.

Any idea how to get access to these settings? Or do I need a usb cable or something?

This resets the trip mileage counter. When this is showing, press the '+' button so that the display shows 'y'. Leave it a few seconds and the trip counter will reset itself.

This will only reset the trip counter, not the total mileage counter!
