Key2
Short press key1 one time：Increase the transmitting power slightly. When the power
up to the maximum, LED2 will blink at an interval of 0.25s.
Short press key2 one time：Decrease the transmitting power slightly. When the power
down to the minimum, LED2 will blink at an interval of 0.5s.
Long press key1：When the long press time reaches 2s, the transmitting
power will continue to increase. The voltage will no longer change after release the
button. When the LED2 flashing, it means the power reaches the maximum.
Long press key2：When the long press time reaches 2s, the transmitting power will
continue to decrease. The voltage will no longer change after release the button.
When the LED2 flashing, it means the power reaches the minimum.
Save setting：The parameter will be automatically saved to EEPROM and does not
need to be set next power on.
