C97 Unicontrol knob erratic behavior

[theclamman]

Hello,

I have a C97 MFD and the Unicontrol knobs behavior is erratic, when you turn the knob left or right to adjust settings it jumps all over the place.

For example, if i turn it to the left to decrease gain it will decrease a few levels and then start increasing. It is nearly impossible to decrease any significant amount because you if your lucky enough to go down 10 levels the next turn of the knob to the left will increase the gain all the way to max.

This behavior is consistent across any function you attempt. I'm at a loss as to how to resolve this?

Welcome to the Raymarine Forum theclamman,

Unfortunately, the reported symptoms are indicative of a UniController which is failing. It is recommended that the MFD be sent to Raymarine’s Product Repair Center to be bench checked / serviced.
