Weird Faint Beeping from EB832

One of my EB832 units has started beeping and I can't figure out why. There are no alarms in Fusion. It's barely audible. Every few seconds it beeps - ever so faintly. It took me a few minutes to narrow it down to that (among all the rest of the gear) but it's definitely the EB832. The beeping stops when I unplug the main power from the wall. I tried unplugging each of the individual plugs from the front but nothing changes. I can't find anything about it in the user manual or other forum posts. Ideas?

@_AV I know you work on these. Is there anything in the guts of these that could cause this?

I can honestly say I have no idea. The sound is almost like there is a beeper inside, but there is none. The best I can think of is a variation on inductor/coil whining noise. Instead of unplugging each individual plug, try turning them off one at a time until all outlets are off and see if the noise goes away.

No luck. Still beeping.

I submitted a ticket with Neptune support. Once I have the phone appointment I'll follow up here with what they have to say.

So weird!
