Attention: The VTX800 supports up to 1600MW, and it is recommended to set it to 800MW when used for a long time. The factory default configuration is 800MW.Before powering on, please make sure to reliably connect the antenna, otherwise it may burn when powered on. VTX800 generate heat during use, which is normal. Please do not touch with your hands to avoid .The higher the power, the more heat it generates. The PCB uses high-end customized materials, and high temperatures not burn out the circuit board. VTX800 should be away from the flight control and in a ventilated position on the aircraft.The heat dissipation module should face upwards and be in a ventilated position in order to continuously dissipate heat. Support manual adjustment of power and frequency, support IRC protocol OSD parameter adjustment.
