    There are two possibilities:
    1) Either you do not change any resistor at all, and then this table applies:

    options starting at 1.200 Volt with the existing sertting of "01110"
    -------1.200-1.250-1.300-1.350-1.400-1.450-1.500-1.550

    Pin22----0-----0----0------0------0-----0------0----0
    pin21----1-----1----1------1------0-----0------0----0
    pin30----1-----1----0------0------1-----1------0----0
    pin31----1-----0----1------0------1-----0------1----0
    pin32----0-----0----0------0------0-----0------0----0


    2)Or you change the resistor as in the picture from Flytek to 50Kohm,
    then this table applies starting from 1.5 Volt for the existing setting of "01110"

    -------1.500-1.525-1.550-1.575-1.600-1.625-1.650-1.675-1.700Volt

    Pin22----0-----0----0------0------0-----0------0----0-----0
    pin21----1-----1----1------1------1-----1------1----0-----0
    pin30----1-----1----1------0------0-----0------0----1-----1
    pin31----1-----0----0------1------1-----0------0----1-----1
    pin32----0-----1----0------1------0-----1------0----1-----0

    In the Picture that FLYtek mailed, the wrong combination of resistor and table was made.
