Bind: Process when the receiver is associated with the transmitters unique code. Requires the bind plug.

Connect: When the receiver is powered on it scans the band for its associted transmitter. When its found the transmitter it will connect.

Once the receiver has been bound to a transmitter, the unique code is stored in memory (along with the failsafes). The receiver should connect with the transmitter within a few seconds of the transmitter being switched on.

I have noticed with my DX7 that sometimes the receiver does not connect and this appears to happen occasionally if the transmitter is turned on after the receiver.
