Which code list does my display use?
Look at how the code appears on your screen:
- E plus two digits (like
E07): the S866 list. - A plain number from 1 to 13 next to an "Error" label: the SW900 list.
- A number followed by "info" (like
03 info): the KT-LCD3 / LCD4 list. - A number from 21 to 30 on a King-Meter or KD display: the King-Meter / KD list.
- A two-digit number on a Bafang system: it depends on the display, because Bafang's lists differ. Check the label on the back: DPC-18, C961, C965, 850C, E162 / E163.
- Flashing lights instead of a number: Bafang E170 / E180 / E181.
