Then the debugging method;
5 After the lid is connected to the receiver, press the F3 key (or the star adjustment key) on the remote control, and the signal strength and quality will be displayed on the TV. The intensity is 60%-70% (this is necessary, but it does not mean that the feeder is not connected properly or the tuner is broken), and the signal quality is 0. Now you can adjust the pot cover and turn the antenna up, down, left and right to find the stars, usually in the southwest direction. Look at the signal quality when turning to make it the highest.
6. Fine-tune the pot cover and tuner to achieve the highest signal quality (70%-80%) (the most important thing is to turn the pot slowly and be patient).
7 Press the remote control to exit. You can watch this program.
