E7D MFD Depth not reading correctly

[[email protected]]

I have a e7d mfd. I purchased the set 3 years ago. The tranducer indicator on the display shows it is transmitting and receiving but it is not displaying a depth. whe a depth is displayed it is incorrect. Any ideas as to what could be wrong?

Welcome to the Raymarine Forum Stan,

It is recommended that you verify that the MFD's Fishfinder application's transducer selection settings (MENU->SET-UP->TRANSDUCER SET-UP->TRANSDUCER) has been configured to correctly specify that model of transducer which has been interfaced to the MFD's transducer socket. If so, then the reported problem may be rooted in the transducer, the MFD's fishfinder circuitry, or in the conditions under which the system had been tested.
