DSM300 transducer problem

Before installing the new transducer, it is recommended that you again duplicate the problem with the currently installed transducer. When the failure occurs, then it is recommended the DSM be powered OFF, that the new transducer be temporarily connected to the DSM, that the DSM then be powered ON and tested for transducer sensing with the with the new transducer. Should the DSM's status LED continue to produce the 1 amber flash code (transducer sense failure), then the DSM should be serviced. Should the DSM's status LED instead flash green, with the new transducer temporarily connected to the MFD then it would appear that the currently installed transducer is indeed bad and should be replaced.
