2.2 Setting failsafe:
TF series receivers support failsafe function for all channels. Follow the steps below to set failsafe:
1) Bind the receiver first, and disable failsafe on the transmitter side;
2) Set all transmitter controls to the desired failsafe position;
3) Press briefly the F/S button of the receiver, the GREEN LED of the receiver will flash twice, indicating the
failsafe is set up successfully.
If you do not need the failsafe function any more, just re-bind the receiver to set default failsafe mode.

FrSky. Be sure to disable any transmitter failsafe settings before setting FrSky failsafe positions. Unusual
jitter may result otherwise.
