Binding of Spektrum satellites can be done either via software (Windows, Android, iOS) or via hardware (CH4-5-6) depending on your preferences.Software: Select the checkbox “Spektrum Bind” at the bottom of the “Receiver selection” page of the WizardHardware: use the bind plug supplied with your transmitter or the bind plug supplied with each one of your receivers and insert it into the CH4-5-6 Brain2 connector.Please keep the following in mind for both scenarios:You will need to cycle power to the unit and also disconnect the USB cable that powers the unitOnce the satellites and/or the receiver have been set in bind mode (fast LED blinking on the satellites) by the iKON2, the binding process is managed by the transmitter only and by the satellite/receiver only. It must be completed by placing the transmitter at a distance of about 2.5/3.5 meters from the satellite/receiver.NOTE: For unidirectional receivers (standard receiver or serial receiver with unidirectional SRXL signal), you must put the bind plug directly into the receiver.
