    What to do if Furuno DRS12A-NXT Radar goes into standby after transmit?

      lewisbillyAug 8, 2025
      If the Furuno Radar goes into standby soon after you set it to transmit and the "TX screen" appears momentarily, it's likely that overload protection has been activated. To fix this, turn off all equipment connected in the network, wait a few seconds, and then turn everything back on.
