We have a 2009 Lowrance VHF that is great but for some reason this year which started at the Friday Harbour gathering every now and then monitoring 16 it starts beeping and kicks down to channel 2. This last weekend away for 3 days was fine till Sunday afternoon and it happened twice while cruising along. When it does that you cannot control the volume so have to hit 16 again. DON"T KNOW
Thanks
