It is possible to use the iKON2 AUX whose output corresponds to the CH2 connector of the iKON2 for this purpose. It is usually preassigned to channel 8 of the transmitter.
If a battery or BEC is already connected to the CH2 connector, just use a “Y” cable to continue using that as a voltage input.
In doing this, any Auto Level and/or Rescue functions assigned to the iKON2 AUX in the Auto Level / Rescue panel of the wizard must be disabled. If you want to use the Auto Level and/or Rescue functions, activate them on one of the three Setups 1/2/3 (preferably in Setup 2 or 3) in the same panel as the Wizard.
