DSM25 Status LED

[Chuck - Raymarine - Moderator]

campion_explorer,

Should the A60/A65 not be producing a bottom plot, then it is recommend that the transducer be inspected to ensure that it is free of marine growth and if a transom mounted transducer, that it is locked in the down position. Should no faults be found, then it is recommended that the system be tested with another compatible transducer which would be simply suspended over the side of the hull in water which will be at least three feet deep below the transducer. Should the problem persist with the test transducer, then the fault would then be isolated to the DSM25. Unfortunately, Raymarine can no longer service DSM25 fishfinder sounder modules and in this case would necessitate replacement of the display and DSM25. This class of displays would typically be replaced with an a67 MFD. The transducer which had been interfaced to the DSM25 (if still operational) may simply be plugged into the a67 MFD's Transducer socket.
