If the wireless trainer unit is connected to the bluetooth port of the transmitter, then the wireless trainer unit will power by the transmitter, the wireless trainer unit needs to bind with another transmitter. The trainer function can be realized after the binding is complete. If the wireless trainer unit is powered by USB interface, then the wireless trainer unit should bind with either of the two transmitters. After the binding is successful, connect the other transmitter to the another end of the USB cable to realize the trainer function. As an example, follow the following steps for binding, if the wireless trainer unit is connected to the bluetooth port of the transmitter:

1. Power on the transmitter that needs to bind with this wireless trainer unit, then let it in the binding state. 2. Connect the wireless trainer unit to the another transmitter, then power on the transmitter. The wireless trainer unit enters the binding state after power-on. And it is in the state of waiting for the completion of the binding . Notes: (1) Please set the three-level switch before the wireless trainer unit is powered on. For an example, if the transmitter uses AFHDS3 protocol, toggle the three-level switch to this position.

(2) When the binding is successful, the LED indicator is always on. During the binding, if the binding is not completed within 10s, the LED indicator enters the flashing slowly and idle state.

(3) After the binding is completed, there is no need to bind again when it is to be powered on next time. Firmware update UPD LED After the three-level switch is set to UPD position, power on the wireless trainer unit and it enters the firmware updating state. When the wireless trainer unit is waiting for updating, the LED indicator will be in a state of three-time flashing and one off.
