Iam running a Manitou ofsprey pro 2009 my in dash depth finder is a Teleflex 112350 (now is owned by VEETHREE instruments) , the other day we were out and in about 6 ft and for no apperant reason the alarm went off on the depth gauge, and stayed on even after shutting down main power the boat has 5 hours the red led light is on the alarm is sounding and there are three lines thru the screen pressing buttons does not help wondering if anyone has heard of this or has a fix Thanks Alot
