Fig. (9): The transmitter
One major advantage of the 2.4 GHz radios is that any receiver only "listens" to one single
transmitter; so it cannot be interferred by other transmitters, operated at the same time. This is
why the transmitter has to be "bound" to the receiver. Binding is already done by factory when
you get the model, but in case it is necessary to repeat the binding please use this procedure:
Connect the model's battery
1.
2. Push the button at the receiver
3. Now swith on the transmitter as
close as possible to the model
Receiver's LED flashes slowly
Receiver's LED flashes in triple intervals
Receiver's LED flashes fast first, then slowly, and
lights constantly in the end
