Hi! You will need to reset the unit to work normally. Try this, remove the battery and press/turn the power button for 10secs. while the battery is removed. Put in the battery and turn the unit on and see how it goes. This should reset the system and resolve the problem. Hope this helps and have a good one!

You have either the DSM250 or DSM300 digital depth sounder module installed. The C80 is not seeing it.
There is an LED status light on the DSM. For starters, it should be lit either red, yellow or green to confirm it is actually powered on. We are hoping for a green light.
Double-check the cable between DSM and C80 for tightness. Also double-check the DSM's power cable for tightness.
The DSM's are sensitive to voltage level onboard. Make sure the DSM's connections to the circuit breaker panel or battery are tight and clean. Double check with a multimeter the there is 12V DC available to the DSM.
Let me know what you find.

I had the same problem last time I was out in shallow water (in less than 2 metres of water) and I suspect that the problem was weed wrapped around the transducer but won't know for sure until I take it out on the water again. I had another problem re water temp which I'll enter separately.
