Turn on your speedo.
Press the set button for about 4seconds until the red and green LED is on. Do not move the throttle on
your transmitter. After 2 secs the red LED is off (neutral saved). During the green LED is on (red off)the
next 3 secs give full throttle, full brake and then back to neutral on your transmitter.
If you press now the SET-button until the 3 short green LED signals occur, all additional functions are
reset to factory settings.
If you don't want to reset the speed controller, just wait for the confirmation signal of the speedo (three
short green LED signals).

curve, 200A current limit and start current, Full Brake=100%, ABS=0=off, Autogas=0, Switch=5.)
The speedo is now tuned to your transmitter.

brake (red) and half throttle area (green).
If it does not, repeat the above section.
