Hi, bought a new robot mower hasq 115H. Put it on the charging base, connected the power up, the charging base has blue light blinking meaning the base is working. But the display panel says "battery problem: 2020-01-01 00:00:05" to that effect, the time changes, now it's about "battery problem: 2020-01-01 00:02:05"
Has anyone had this issue? Is it because I didn't connect the boundary wire? Thanks
