Setting Instructions

1. Short press "Set" to interchange display the 4 values:
   1. FR1: PWM1 frequency
   2. dU1: PWM1 duty cycle
   3. FR2: PWM2 frequency
   4. dU2: PWM2 duty cycle
2. press"Up" and "Down" to set the current value

1. Set the PWM frequency:
   • "S1FXXXT": set the PWM1 frequency as XXX HZ(0001-999)
   • "S1FXX.XT": set the PWM1 frequency as XXX KHZ(00.1-99.9)
   • "S1FX.X.X.T": set the PWM1 frequency as XXX KHZ(0.0.1.-1.5.0.)
     • S1->PWM1; s2->PWM2; F->frequency; D->duty cycle; T->Stop bit
2. Set the PWM duty cycle:
   1. "S1DXXXT": set the PWM1 duty cycle as XXX(001-100)
   2. "S2DXXXT": set the PWM2 duty cycle as XXX(001-100)
3. DOWN: set successful
4. FALL: set fail
