FUNCIONAMIENTO TELECRANE F21-E1

[@leonandi4cu]

hello, i have exactly the same device. The problem I think is with the console or is it just my ideas. Description of the problem: when I insert the battery, the red light flashes quickly on the indicator. I checked the buttons according to the instructions, there are no sticking, the emergency button is not clamped. I am an electronics myself. There are no services in our area. Can you help me with something, or at least give me a schematic for the device? Please!
