-Powering on the VTX, blue LED display 0, indicating the VTX is powered on , but it is in off status without any transmission.
-Short-press the button to change channel(CH), digital display will change synchronously. Digital display changes cyclically from 1 to 8.
-Long-press the button for 2 seconds until digital display flicker. Then short-press the button to change the frequency band(FR), digital display will change synchronously. Digital display changes cyclically from A, B, E, F, R, U, O, L, H.
-Long-press the button for 5 second until digital display flicker. Then short-press the button to change the power, 25mW/50mW/200mW(one hyphen stands for 25mW, two hyphens stand for 50mW, and three hyphens stand for 200mW).
-5 seconds after setting, CH, FR and power will flicker alternately.
