Insert the binding cable into the receiver's BIND port. 2. Plug the power cable into any other port, and the receiver's LED will start to flash quickly indicating that it has entered bind mode. 3. Put the transmitter into bind mode; (See the transmitter's instruction manual for more information.) 4. Binding is successful when the receiver's LED starts to flash slowly. Remove the power and bind cables from the receiver *if the transmitter is bidirectional the reciever status indicator will not fash slowly. 5. Reconnect the power cable to the receiver. 6. Check to make sure that the transmitter and receiver are working as expected, if there are any issues or unexpected operation follow the steps above to bind again.
