Weedlines,

Should the MFD be operating with LighthHouse II v19.03 or LightHouse 3 software, and should the vessel be located in the water, and should the depth of the water beneath the transducer be greater than 3', and should the problem persist, then it would be recommended that the currently installed transducer be tested by a Certified Raymarine Installer who having a CHIRP transducer tester in his kit. If no fault is found with the transducer or should a Certified Raymarine installer be unable to perform this service, then the CP470 and Adapter Cable may be sent to Raymarine’s Product Repair Center to be bench checked / serviced.
