Insert the bind cable into the receivers bind port 2. Plug the power cable into any other port, & the receivers LED will start to flash quickly indicating that it has entered bind mode 3. Put the transmitter into bind mode; (See the transmitters instruction manual for more information)4. Binding is successful when the receivers LED will stop flashing Remove the power & bind cables from the receiver.5. Reconnect the power cable to the receiver 6. Check to make sure that the transmitter & receiver are working as expected, if there are any issues or unexpected operation follow the steps above to bind again. Note: Ports used to connect the receiver to the various components BAT: Separate power supply interface for t
