1、Default Output: 5733MHZ(5.733GHZ)/1.6W. 2、Support manual power and frequency adjustment, support IRC protocol OSD tuning reference. 3、Built-in microphone for real-time sound transmission. 4、The map transmitter has a built-in temperature detection module, at the 1.6W Level if the temperature is too high for a long time, it will automatically reduce the output power. 5、When the temperature drops, it will increase to the maximum power output again. The surface temperature of the maximum power is around 115-120 degrees when the unit is left stationary for a long time.
