Binding steps of all transmitters and receivers from RadioLink are the same as follow:
1) Put the transmitter and the receiver close to each other (about 50 centimeters) and power both on.
2) Switch on the transmitter and the LED on R8EF will start flashing slowly.
3) There is a black binding button(ID SET) on the side of receiver. Press the button until the LED flashing
quickly and release, meaning binding process is ongoing.
4) When the LED stops flashing and is always on, binding is complete. If not succeed, the LED will keep
flashing slowly to notify, repeat the above steps.
1.3 Note of Receiver Usage
1
Keep antennas as straight as possible, or the effective control range will reduce.
2
Big models may contain metal parts that influence signal emission. In this case, antennas should be
positioned at both sides of the model to ensure the best signal status in all circumstances.
3
Antennas should be kept away from metal conductor and carbon fiber at least half inch away and no
over bending.
4
Keep antennas away from motor, ESC or other possible interference sources.
5
Sponge or foam material is advised to use to prevent vibration when installing receiver.
6 Receiver contains some electronic components of high-precision. Be careful to avoid strong vibration
and high temperature.
7 Special vibration-proof material for R/C like foam or rubber cloth is used to pack to protect receiver.
Keeping the receiver in a well-sealed plastic bag can avoid humidity and dust, which would possibly make the
receiver out of control.
1.4 T8FB Calibration
Press rudder trimmer left and turn on transmitter at the same time.
When the transmitter is power-off, toggle both sticks at the central point. Then press the rudder trimmer button
left and the power button simultaneously, red and green LED will start flashing and the T8FB is ready to be
calibrated..
Range Calibration: Toggle both sticks (Ch1-4) to the highest point/maximum and the lowest point/minimum.
Then back to the central point. (Refer to image below)
Central Point Calibration: When the joysticks are back to the central point, press rudder trimmer right, and
then red and green LED always on means sticks calibration is done with success. Then turn off T8FB and
repower it on.
