Yes. Our system has inbuilt error checking circuits to provide audible and visual warnings if the fuse that operates the Transducer should blow. If the internal fuse (2 Fuses, Transducers 1 and 2 connected to FUSE 1 and Transducers 3 and 4 connected to FUSE 2) should blow the unit will give an audible beep, an error light on the facia and the LCD will give clear text error status and tell you which Fuse has blown. This warning will go out when the fuse is replaced. ensure you turn the module off before replacing the fuse and back on once replaced.
