Neighbor just got a HDS 9 carbon and the sonar is not working any hints

Thing plugged in properly ??

Carbon are dual channel sonar.

He needs to select the correct channel for the transducer that is selected. And then (if the transducer is not an XSonic) go into sonar installation menu and make sure the correct transducer is selected. If its a XSonic model it will be automatically detected and the model willbe greyed out in the sonar installation menu.

Its covered in the manual if he needs details on how to do that.

thanks got it now was on the wrong channel.
