    Default Doosan DNM 400 "APC" flashing?

    On the bottom right hand corner of the photo there is a yellow "APC" light / icon that keeps flashing on my Doosan DNM 400. Does anyone know what this is? It never done it before started when I started the machine. Flashes on and off all the time. Machine runs fine. Shut machine off and back on, it's still there. Not sure what it stands for. Looked at manual briefly, not sure to look in Doosan or fanuc manual. Don't have a pallet changer. I looked online a little I found something that may have referenced a communications issue. Anyone have any experience?

    The APC alarm is probably the Absolute Pulse Coder battery low alarm.

    Thanks, thats what it is. Called service guy asking about it. This is kind of dumb. It's a low battery that keeps your axis position when the machine is off, but it's not an actual alarm or have any sort of message. Just an ambiguous flashing on the screen. Just out of curiosity is this like a first warning and a more obvious alarm comes later that has an explanation?
