To restore settings on a Yolin YL81F using a K6 controller:
1. Enter the main setting interface. 2. Ensure the speed is at 0. 3. Press and hold the "+" and "-" buttons simultaneously for 2 seconds to enter the restore factory default setting interface. 4. Use the "+" or "-" buttons to toggle to "dEF-Y" (to restore defaults). 5. Press the confirmation button (often the power or mode button) to confirm. 6. The display will show "dEF-0" for a few seconds and then automatically restore the factory default settings. 7. The display will exit to the setting interface automatically.

Why does the menu structure of the YL81F display on my Burchda RX80 bike differ from the menu structure in this manual? For example, I can't set any PAS level ratio values on my display. This submenu does not even exist.
Likewise, the PAS level settings on my display cannot be found under 03P, but under 05P.
