Axiom/RV-100 installation

JPA,

The problem of the system reporting that no transducer was detected may indeed be associated with a failing B60 transducer, particularly as this problem had been previously observed when the same transducer had been interfaced to the DS500X. This problem may also be resulting from insufficient power, particularly as the problem manifested itself at slow speed (low engine RPMs - low alternator output) and while at the dock. It is recommended that power be ruled out by
1) connecting the vessel to shore power and permit the batteries to obtain a fully charged state
2) after completing step 1) and while still connected to shore power, operate the system for an extended period of time

Should the failure not occur when tested in the manner specified above, then it would appear that the system's batteries need to be serviced and/or additional battery storage needs to be added. Should the failure occur when tested in the manner specified above, then it would be recommended that the MFD be tested with another compatible 50kHz/200kHz transducer which will simply be suspended over the side of the hull. Should the problem not occur with the test transducer, then the currently installed B60 should be replaced. However, should the problem persist with the test transducer, then it would be recommended that the MFD be sent to Raymarine’s Product Repair Center to be bench checked / serviced.
