"Yolin YL-81C Display" on a Engwe M20

[warhog]

So on P19 screen if you long press the "i" button does your screen then go to the main menu screen? Or can you short press the "i" button & return to the main menu screen?

if i hold i its just going back to 19 and if press i its just switching between the numbers

Ok if you turn the bike on/off or vice versa, does your main menu screen appear on your display. Or does it automatically go to the P19 setting screen.

Ok on that screen on the 1212 code, enter the 1st number & press "i" then go to the second digit with the "+" & enter 2 & press "i" & so on till you got the 1212 code entered & then long press the "i" button. Then after that short press the "+" button. I think then it should return to the main menu screen.

Let me start over, & ask. What was wrong with the bike when you recieved it. After you charged the batteries & turned the bike on for the very 1st time. What was wrong? Or what did not work? Thanks.
