The LED board
The LED board acts as "distribution box" for the ECU data bus, and also features three LEDs
which provide information about the current state of the Jet-tronic. Ideally the LED board should
be installed in the model with the outward facing socket (close to the three LEDs) easily
accessible, and the LEDs clearly visible. The outward facing socket is normally used for
connection to the GSU (= Ground Support Unit) for servicing and programming. The LED board
also includes a small push-button which is used in the procedure for "learning" the radio control
system; it also serves to activate the "manual mode".
