Reset trip on my brilliant Haibike SDURO 3.0?

[malcolmr]

This is my second day of ownership and its all lovely -except I am travelling greater and greater distances but not able to record a particular spin.
Can anyone help now ? A problem was posted some months ago but I missed the solution.
Thanks much

Hello.
Might be a bit of a late reply but on my haibike you long-press the up and down buttons.
