I did do a forum search for any possible answers to my query but nothing came up.
We are having connection problems with our Inmarsat-C. It’s a Furuno Felcom 15. Each time it is powered up an alarm of ‘External NAV Equipment Failure’ goes off. Once we manually input our position the alarm still sounds. All of the internal tests come back as good (PV, Diagnostic, and Distress Alert Button Tests). We’ve checked all of the cables for potential loose wires or wires being pinched but have found nothing that looks to be the cause.
I have contacted Furuno for assistance but as of yet they have not gotten back with me.
Any suggestions on my next course of action?
