For two days our battery monitor bmv700 has been lit up and flashing between “0200ah” and “ _200 ah”. Its in setup mode. any attempts to snap it back into the regular mode arent working. Pressing + or - or ‘select’ flash up the part of the menu its stuck in “01 ba”. Holding down - or + or ‘select’ just scroll through the whole “01 battery capacity”. Nothing happens when we press or hold ‘setup’. Any advice? We didnt put it into this mode - so wondering if.. a fuse might be gone or some thing?
