2. Set Up
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
TFR8SB support two selectable failsafe setting options either use native failsafe position preset on the transmitter side
or set failsafe on TFR8SB.
2.2.1 Use native failsafe position preset on the transmitter side:
If not disabling failsafe on the transmitter side TFR8SB will use native failsafe position preset on the transmitter side.
2.2.2 Set failsafe on TFR8SB side:
TFR8SB supports failsafe function for all channels. Follow the steps below to set failsafe on TFR8SB:
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.
I f you do not need the failsafe function any more just re-bind the receiver to set default failsafe mode.

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.
Note: HS mode is only applied for high-speed digital servos. Other servos should select FS mode otherwise servos will get hot or even burn out.
4. Channel Setting Methods
Channel setting for Futaba S.BUS servos and FrSky S Bus compatible servos can be performed at TFR8SB.
1 Connect the SB port and RSSI port by the provided cable.
2 Connect an S.BUS servo or S Bus compatible servo to the output connector (1~8) corresponding to the channel you want to set.
3 Connect battery to the receiver RED blinking LED indicating the channel setting is completed in Mode A. To switch to Mode B press the button on receiver for three seconds until GREEN LED starts to blink indicating the channel setting is completed in Mode B.
Mode A: RED LED blinks
Mode B: GREEN LED blinks
Note: Do not perform linking procedure while motor’s main wire is connected or engine is operating otherwise damage may occur. After linking is completed recycle the receiver power and check if the receiver is really under control by linked transmitter.
