[CA] [CA11] TRANSDUCER FOR MFD E7D

[Chuck - Raymarine - Moderator]

Jose,

I was not seeking the identification tag from a box. I had requested a photo of the identification tag which is affixed to the plug end of the transducer's cable to ensure that the A80173 was the transducer which had been installed. Should the specified tag list the Raymarine part number A80173, then it should be possible to select the 200kHz or 1kHz Channel (MENU->CHANNEL) from within the Fishfinder application. Should the specified tag list the Raymarine part number A80173, then this transducer should also be automatically recognized as a 1kW fishfinder transducer by a Raymarine's ax7/cx7/e7D/ex7/eSx7 MFD (where x identifies the MFD's screen size) and the Fishfinder application's transducer list (MENU->SET-UP->TRANSDUCER SET-UP->TRANSDUCER) should list 1kW transducers, including the B164. If the B164 is not listed within the Transducer list of the Fishfinder application, then it would be recommended that the resistance across the A80173 transducer's sense pins be measured. For 1kW transducers (i.e. the A80173 B164 (20 degree) - Sonar Transducer, the measured resistance should be approximately 3 kohms between pins 5 and 6 (see below). No resistance (i.e. short) should be measured if the transducer is a compatible 600W transducer. If so, then it would appear that the MFD's internal fishfinder sonar circuitry may have suffered a failure and it would then be recommended that the MFD be sent to Raymarine’s Product Repair Center to be bench checked / serviced.
