Carbon 12 beeping all the time?

I'm have a problem with my Lowrance HDS Carbon 12 beeping all the time. It doesn't have a steady rhythm. The depth alarm is definitely off. It does it while I'm running but I can't hear it for the outboard but, as soon as I stop, I can hear it and it's really annoying.

See pages 175-177.

The most common alarm on T Birds pages is the GPS. If you can't find it turn off one at a time until it stops.

Look for the alarm circle at the bottom right and see what the alarm is for. Like larry said, if you don't have line of site to satellites you will get the alarm and you need to turn off or reboot.
