Gen2 12 touch annoying beeping needs to stop

[DaLa]

Thank in advance,

I have turned off all alarms I can find but my unit on a 2015 boat beeps warnings for shallow water and such and I cannot find the proper menu to turn off or lower sensitivity. I would like to remedy this frequent beeping before I get "used to it" I'm fishing the delta and shallow a lot...

When it does it the Unit displays white "snowflake" shaped icons that may be a shallow water warning symbols...

My gen3 up. Front is not acting the same.

Help, thanks,
Dave
