"Learning" the radio control system

Before the Jet-tronic is used for the first time, it has to be "taught" the radio control system's stick positions
for the throttle stick, and the positions of the three-position switch.
This is the procedure:
1. Switch off the electronics and connect the two servo leads attached to the ECU to the receiver (THRottle
= throttle stick, AUX = 3-position switch). Connect the pump battery (see wiring diagram).
Connect the Ground Support Unit (GSU) to the electronics (optional).
2. Switch on the transmitter, and reset the throttle channel and switched channel to the default settings, i.e.
all Dual Rates, Exponential, "servo slow" functions for the throttle stick and the switched channel should
be either switched off or reset (= 100%). If your transmitter features a special idle throttle trim function,
switch the function on. However, this is not absolutely essential, and the turbine control system will work
properly without it.
3. Press and hold the "Select Menu" button on the GSU, then switch on the Jet-tronic (via the receiver
switch).
* Note:
The small button on the LED board can also be used instead of the "Select Menu" button on the
GSU.
Release the button as soon as the three LEDs flash in the following sequence:
LED
Standby
Pump running
OK
The GSU screen simultaneously displays the message:
Release key to:
- learn RC -
This procedure calls up a special operating mode (-> "Teach In") for teaching the system the stick positions.
When you release the button, the green "OK" LED lights up.
The GSU screen now displays the message:
Set Throttle to
minimum:
l
The first step in the "learning" process now occurs: the setting of the throttle stick position in the "OFF"
position. You move the throttle stick to idle (back end-point) and the throttle trim to "OFF" (back position).
When you have done this, press a button -> the red "pump running" LED lights up. As a check, the GSU
screen displays a numeric value at bottom right, which changes to reflect the stick position (= pulse width of
receiver signal). Once you have stored the "OFF" stick position (by pressing a button), the GSU screen
displays the next step:
