Setup with two separate speed controllers:
1. Connect throttle channel M1, M2 and all proportional channels you are using.
2. All channels and the trim must be in neutral position on your radio. Switch on
transmitter first and then the SFR-1-D.
3. Activate the setup, with the blue „setup“ button on the SFR-1-D board, until
the green LED flashes fast. The blue LED flashes once.
4. With correct signals at the throttle channel X2/1 and X2/2, all neutral positions
are evaluated and stored. If the red LED is flashing, the SFR-1-D can not
detect a correct signal at X2/1 or X2/2. Please check all connections and start
the complete process again.

and return to neutral position.
6. Wait until the blue LED flashes two times and lights permanently.
7. Within 20 seconds press the throttle stick of the left motor down and give full
throttle backwards and return to neutral position. The blue LED flashes three
times. The green and red LED are flashing fast.

neutral. The blue LED is flashing 4 times und stays on afterwards.
9. Within 20 seconds turn the throttle stick of the right motor completely to full
throttle backwards and return to neutral. The blue LED flashes 5 times and
