FrSky Futaba FASST Compatible 4Ch 2.4Ghz Receiver

1) Compatible with FASST 2.4G: Air Systems (7CH Mode/Multi Mode) & Surface Systems (C1 Mode);

3) Lighter weight and physically smaller;
4) Two selectable failsafe setting options.

 

Turn on the transmitter, connect the battery to the receiver while pressing receiverΆs 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.

TFR4-B support two selectable failsafe setting options, either use native failsafe position preset on the transmitter side, or set failsafe on TFR4-B.

If not disabling failsafe on the transmitter side, TFR4-B will use native failsafe position preset on the transmitter side.

TFR4-B supports failsafe function for all channels. Follow the steps below to set failsafe on TFR4-B:
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.

If CH3 and CH4 are connected by a jumper, CH1 will output CPPM for CH1~CH8, and CH2 will output RSSI (PWM).
