[CA] [CA11] CPT-S to Axiom Pro S

[Chuck - Raymarine - Moderator]

Welcome back to the Raymarine Forum Angler Management,

I'm glad to learn that the CPT-S transducer had been working so well for Should you not already have done so, then it is recommended that you verify that the MFD has been updated with LH3 v3.11.42 or later software and that a Power ON Factory Reset be performed. If so, then the problem may be rooted within the transducer or within the MFD itself. Typically, such fault isolation would be performed by testing the MFD with CPT-S transducer which was known to be operational. The test CPT-S transducer need not be installed or be in the water ... just connect it to the unpowered MFD and then determine whether the MFD detects the transducer. If not, then it would unfortunately appear that the MFD's fishfinder circuity has suffered a failure and would need to be replaced by the dealer (if purchased within the last 30 days) or sent to Raymarine’s Product Repair Center to be bench checked / serviced.
