If you turn your transmitter on first, and then your receiver, the lights should come on steady. The only time they should flash is when you're binding (inserting the binding plug etc..) of if you turn the reciever off and on without turning off the transmitter. An example of that would be changing batteries without turing the transmitter off.
This statement is not true.
A Spektrum receiver flashes RAPIDLY when the bind plug is inserted and the unit is turned on prior to the transmitter...as it should be when binding.
They will also flash SLOWLY when the receiver is indicating that a signal fade or loss has occurred. This will happen during 1 of 2 times:
1) After a flight, if signal loss occurred during the flight. It will not tell you when it occurred, how often, or to what extent...merely that at SOME point(s) during the flight, the signal faded.
2) It will also happen during an otherwise normal startup sequence (TX on, then RX) if the TX is too close to the RX (4' is the recommended distance), or if the RX is turned on too soon after the TX (5 seconds seems to be a good wait time). The RX is indicating that there was an error in its initial attempt to synch with the TX. This is not a safety of flight issue, but it DOES eliminate the Rx's ability to tell you that a fade occurred at some point during the flight, since it will be flashing from the start.
===========
There is no inherent reason a Spektrum RX should flash simply because it was turned off and on with the TX remaining on. You're presenting absolutely nothing to the RX in that condition that you don't ALWAYS present it with during a normal startup.
