Binding
To ensure good signal strength, make sure the receiver antenna
is as far away from any metal parts when installing the receiver.
①Insert 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.
③Put the transmitter into bind mode; (See the transmitter's instruction manual for more information.)
④Binding 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.
⑤Reconnect 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.
