7 Sets of PWM Channels:with channels 1-6 labeled as receiver 6 channels and – + CH7 being the 7th channel of the receiver
The sound group is activated by CH4, when the four-way is not turned on, only the steering will have sound effects; when the four-way is pressed, there will be the sound effects of adding or subtracting throttle as well as reverse.
If you don’t turn on the sound group, only the left and right turn signals are linked, and other lights can’t be turned on; but when the sound group is turned on, the brake lights, blinker lights, reversing lights and headlights can be turned on and off according to the throttle situation.
(ote: The sound group needs to input a voltage of 6V/3A or above, and a current that is too small may affect the effectial of the sound group.)
