RC4GS - V6.0.1 (Compatible with RC4GS produced AFTER Jan.1, 2018 ONLY)
The other models RC6GS with 2-position switch, RC4GS produced before 20180101, T8FB, T8S, RC3S
and RC4G can bind to R7FG though the functions of 2-
way transmission and subsidiary ID can’t be
realized.
1.2 Binding
Each receiver has an individual ID code and must bind with transmitter before using. When the binding is
done, the ID code will be stored in the transmitter and there’s no need to rebind. Therefore, when a new
R7FG is purchased, binding needs to be done in order to work with transmitter.
Binding steps:
1. Put the receiver and the transmitter together within about 50 centimeters.
2. Power on the transmitter and R7FG will bind to the closest transmitter automatically.
3.
Press the ID SET on the receiver’s side for more than 1s and the GREEN indicator will
flash, meaning the binding process has begun.
4. When the GREEN indicator stops flashing, binding is complete.
5. Test the model servo to make sure it can be operated by the transmitter.
