2.Setup

2.1 Bind procedure:
Turn on the transmitter, connect the battery to the receiver while pressing receiver�s F/S button. After the RED LED is off and GREEN LED is solid, the binding process is completed and the receiver is operating normally.

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.

Warning: Some transmitter manufacturers use a failsafe method that can interfere with that used by FrSky. Be sure to disable any transmitter failsafe settings before setting FrSky failsafe positions. Unusual jitter may result otherwise.
2.3 LED status:

RED LED	GREEN LED	Mode
Off	On	Normal mode
On	On	Waiting to be bound
Flashing	On	Signal lost

3. How to switch between two PPM modes
Turn the transmitter off, connect the battery to the receiver, press the F/S button of receiver for 6 seconds and then release. The red LED will flash fast in HS Mode and slow in FS Mode.Repeat this to alternate modes.
Warning: HS Mode is only applied for high-speed digital servos. Other servos should select FS Mode, otherwise servos will get heat or even burn out.
