Sorry for not understanding.
Well the Naza doesn't detect signal loss per se... Your receiver is going to send its failsafe values to the Naza when the signal is lost, and that's what it sees. So the receiver goes into failsafe, sends its failsafe values to the Naza, and the Naza goes into failsafe. If the failsafe value isn't setup right though, Naza won't know to go into failsafe. For example, if your failsafe value on your RX keeps it in GPS mode, then it will stay in GPS mode when signal is lost. At least this is the way I've understood it to be.
