RE: SPEKTRUM AR6200
You're having something other the lost bind. When you understand how the new 2.4 system works you'd know that once you bind a receiver to the transmitter it can not "lose bind"
The GUID number is programed into the receiver. This applies to all radio systems.
If you programed failsafe and the plane goes into failsafe that indicates a loss of signal, blinking lights on the receiver shows loss of power.
Take Andy's advice. Dennis
