Hi readers, I’m using the BMV 700 for several years now without problems. Today I disconnected the battery for a moment. When reconnecting the battery (without changing anything in the system setup), the Bmv started flickering without any text visible. When pressing the buttons ‘select’ and ‘set up’ together, the flickering stops and the display shows: ‘bl 102’ . When pushing another button, the display went blanc and after a while started flickering again. What does bl 102 mean and how to get the bmv working again?
