Hello everyone, I'm a technician here in Rosignano Solvay (Tuscany Italy) I have a problem with a NAVNET 3D (MCU001) It doesn't show any image on the monitor, I thought about the video card, which I replaced, but it wasn't her. I noticed that when I turn it on it emits two beeps from the control keypad, but then some beeps come from the box at a lower volume.
about four that repeat continuously... I thought about the backup battery, I measured it and it is 2.8 V. I visually checked both the power supply board (power board assembly) and the second power supply. But it's all right. It's possible that the 2.8V battery isn't making the motherboard work. Can anyone tell me what to check. Thank you and Happy Christmas
