MFD and transducer

[Chuck - Raymarine - Moderator]

stbatton,

It is recommended that you verify that you have correctly configured the MFD's Internal Sounder for the model of transducer which has been interfaced to the MFD. With the MFD interfaced only to power and to the transducer:
- Select HOME->FISHFINDER to display a full screen Fishfinder application page
- Select MENU->CHANNEL->200KHZ
- Select MENU->SET-UP->TRANSDUCER SET-UP->TRANSDUCER->B744V/B744VL/SS5...

Afer doing so, should the problem persist when interfaced only to the power and to the transducer, then it would be recommended that a System Settings Reset (HOME->SET-UP->MAINTENANCE->SYSTEM SETTINGS RESET) be performed and that the MFD's setting then be manually re-configured. Should the problem persist thereafter, then it would be recommended that the MFD be tested with another transducer which is known to be compatible an operational in all respects. Such testing may be performed by yourself or by a Certified Raymarine Installer. Alternatively, the MFD may be sent to Raymarine’s Product Repair Center to be bench tested/serviced.
