Settings

1. Set the OUT-1(Vx) voltage

• Output voltage indicators, 5V Red, 6V Green, 7.2V Green, 12V Blue

• Press and hold the button for 3 seconds to enter the setting of the OUT-1 voltage.

• The LED on the current output voltage will blink. then press button to choose the voltage between 5V(Red), 6V(Green), 7.2V(Green), 12V (Blue) .

• The value will be saved if no button action within 3 seconds.

2. PWM control

• PWM Freq & Range:  50Hz-330Hz, 900-2100

• OUT-1 Default output is ON if no PWM signal connected

• Connect the PWM pin and GND to a spare PWM channel on the receiver or flight controller.

• OUT-1 will be turned OFF when the auxiliary switch’s pwm value becomes higher than 1800. It will be turned ON when the value falls below 1200.
