3. Button ⑤ is the power adjustment button, which switches the power level by short pressing once, between 25KW and 2.5W
Cycle between the four gears of 5W and 7W. The green LED is the power indicator light, as shown in the following figure. It flashes once at 0mw, twice at 25mw, three times at 3W, four times at 7W, and five times at 10W. Press and hold for 3 seconds to enter pit mode, with the green light constantly on.

Note
This image transmission has a temperature protection function. When the temperature of the image transmission is higher than 100 ℃, the transmission power of this image transmission will decrease by one level. If the temperature is still higher than 100 ℃, it will continue to decrease by another level until the lowest power level (1W) is reached; At this point, the temperature of the image transmission will decrease. When the temperature drops to 95 ℃, the transmission power will return to the originally set power level.

Beteflight Frequency Definision
1. Users can choose any desired frequency point within the range of 4867mhz-7210mhz, such as 4888mhz, 4999mhz, 5111mhz, etc;
2. The value entered in Betaflight corresponds to the frequency point, such as the frequency point desired by the user
Notice For Use
In Betaflight, the user sets a frequency point that is not in the image transmission table, such as 4888MHz. In this case where the flight control is connected to the IRCTramp protocol for image transmission, the user will not be able to use physical buttons, and the blue and red lights will remain on continuously. The green power light will not be affected
If the frequency used is within the image transmission table, the lights will flash in the described flashing manner;
The priority of the IRCTramp protocol for flight control and image transmission set by Betaflight will be higher than the definitions of physical buttons and image transmission tables; Assuming the flight control is already connected and the frequency point is set to 4999, the image transmission has been automatically saved
4999 is the frequency point for this image transmission. If you need to use the frequency point in the image transmission table that is not connected to the flight controller, short press the frequency point to switch to the default A1 frequency point in the image transmission table;

Product Wiring Definition
Notice For Use
1. When installing image transmission, it is necessary to leave space to ensure air convection around the module and ensure module heat dissipation; Otherwise, the module overheating protection will activate, reduce power transmission, or even turn off power transmission.
2. It is recommended to ensure the correct voltage range and positive and negative poles before connecting the power supply to avoid burning out the components.
3. It is recommended to ensure that the RF output terminal has an antenna installed before connecting the power supply, which can extend the service life of the module.
4. Please read the instruction manual before use, as this will ensure proper wiring and extend the lifespan of the module.
