1: K2 will only activate the PD function when the screen lights up by pressing the lightning button

2: When pressing the OK button to turn on the screen, PD is not supported, and entering PD spoofing or protocol detection will result in a black screen or repeated restarts

3: TYPE-C data plug K2 female socket can be flipped over and plugged in again if the screen does not light up after pressing the lightning button

4: The HID interface on the side of K2 is connected to a computer and cannot detect the protocol

5: K2 testing protocol will restart multiple times, which is a normal phenomenon. Do not connect the HID port for power supply during protocol testing
