Insert the binding cable into the receiver's BIND port.<br/>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.<br/>3. Put the transmitter into bind mode; (See the transmitter's instruction manual for more information.)<br/>4. Binding is successful when the receiver's LED starts to flash slowly. Remove the power and bind cables from the receiver <strong>*</strong>if the transmitter is bidirectional the reciever status indicator will not fash slowly.<br/>5. Reconnect the power cable to the receiver.<br/>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.</p>
