Before turning on the power, you must make sure that an antenna has been installed at the image transmission end, otherwise it will Will damage components(Antenna not included) 2. High temperature will be generated when image transmission is working. Please do not touch it directly with your hands to avoid burns. 3. Leave space at the image transmission installation location to ensure air convection around the module. Module heat dissipation. 4. When using this product, please comply with local radio laws and regulations, and use locally permitted Channel frequency. 5. Before turning on the power, make sure the voltage range is correct 7-36V, and the positive and negative poles are correct to avoid damaging the components. 6. Use high-quality antennas to ensure effective output of image transmission performance. 7. If the image transmission is in a static state for a long time after being powered on, set the power to the minimum. type:4.9G Colour:Black Material:Metal Package Contents: 1 x 2.5W 48CH VTX 2 x Connecting cable Only the above package content, other products are not included.
