Відео приймач 1G3SE 1.2/1.3ГГц
1 Button control and LED indicator light
1. Nine red indicator lights are frequency point indicator lights. Press the button briefly to switch to the next frequency point.
This operation can be repeated, and the corresponding frequency indicator light will light up every short press.
Note: This operating system has a memory function, and after a power outage, the system will save the current frequency point. 2、 Interface definition:
