Includes: 1 x GEPRC RAD Tiny 5.8G 400mW VTX 1 x black 1.13 copper tube antenna 1 x SH1.0-5P plug silicone cable 1 x SH1.0-3P plug silicone cable 1 x GEPRC RAD Tiny 5.8G 400mW VTX Manual Function Button and indicators instruction: -Press and hold for 2S to start from the frequency point. Cycle through frequency points (green indicator light), channel groups (blue indicator light), and power (red indicator light). -After the corresponding function is selected (the corresponding indicator light is on), press it immediately to cycle through the functions. -Press and hold the side button for 2 seconds, the blue light will flash, and enter the frequency adjustment mode. Short press to switch the frequency points CH1 to CH8, select a frequency band and the indicator light will flash corresponding times. -After switching the frequency point, press and hold the button for 2 seconds again within five seconds. The green light flashes to enter the channel adjustment mode. Short press to switch channels. Band A (flashes 1 time); Band B (flashes 2 times); Band E (flashes 3 times); Band F (flashes 4 times); Band R (flashes 5 times); Band L (flashes 6 times). -After switching the channel, press and hold the button for 2 seconds again within five seconds. The red light flashes to enter the power adjustment mode. Short press to switch power: 25mW (flashes 1 time); 200mW (flashes 2 times); 400mW (flashes 3 times). ); PIT Mode Notice: -When installing the image transmission, space must be left to ensure air convection around the module and ensure heat dissipation of the module. Otherwise, the module overheating protection will activate, reduce power transmission, or even turn off power transmission. -It is recommended to ensure the correct voltage range before turning on the power. The positive and negative poles are correct to avoid burning out the components. -It is recommended to make sure that an antenna has been installed at the RF output end before turning on the power, which can extend the service life of the module. -Please read the instruction manual before use so that you can wire it correctly and extend the service life of the module.
