[CA] [CA11] Axiom 9 RV Sounder issues

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum cgcothran

In the case of ktcarter, we believe that the problem is rooted within the MFD's fishfinder circuitry or that of the low power / high frequency conical CHIRP element of RV transducer. This is evident in the faint bottom return shown within the Sonar channel of both videos. In this case, it would be recommended that the MFD be tested with RV transducer or that the MFD along with the transducer be sent to Raymarine's Raymarine’s Product Repair Center to be bench checked / serviced.

Following the LightHouse 3 v3.9.46 software update, it is recommended that a Power ON Factory Reset be commanded to address any anomalies or instability of the system following the software update. Should you have performed this reset and should the problem persist, then please respond accordingly.
