Turn off Fishfinder

[BAYSAILOR6547]

My boat is in winter storage. I want to operate my C97 MFD without having the Fishfinder send out a signal to the concrete below. Is there a way to disable the Fishfinder temporarily?

Hello Baysailor,

If you are using the MFD's built in sonar module, just unplug the transducer cable from the transducer port on the back. Make sure the display is OFF before you do this. If you are using an external sonar module, first identify the unit and then unplug the POWER cable from it. **Never unplug/plug a transducer from/into a powered on sonar module. If your display is your sonar module, make sure the display is off first. Unplugging a transducer from a powered ON sonar module could potentially damage both the transducer and sonar module.**
