VAVA dash cam as gift

Received as gift, installed but can’t record more than 20 seconds. How do set it to record whole trip or when I turn it off?

snapshot button records for 20 seconds (if you hold button for 3 secs) but loop is always recording while camera has power and an SD card. The loop is a series of short videos of your entire trip (at least until you run out of SD space then it overwrites the oldest videos). “Short” is selectable as 1, 2, or 3 minutes in settings.
