I bought this RC 304 me about 5 weeks ago. The installation (station, perimeter wire) was, acc. To instructions described very well and easily. After about 3 weeks mowing he stayed then suddenly in the middle of the lawn and pointed at E3, so there is no contact. I have checked all electrical power and then checked the loop sensor (perimeter) by visual inspection and with a power meter. Are you all right, but the Robomow displays permanently at E3. Now I have to see who takes over the customer service here. Has anyone here might have the same experience, or can someone give me a tip wg. Provide customer service? Otherwise, I am satisfied with the mowing and the result!
