More coil whine, APC UPS power rail hum & fizz !!! HD

I could not imagine we get to another coil whine, grid hum and fizz video so quickly. APC UPS another bad example of office noise pollution :-/ APC "PRO" UPS 550: http://services.exactcode.de/amzn.cgi?index=electronics&keywords=APC%20UPS Sorry for the awesome "made with iPhone" video quality. Looks like the auto-focus did not do the best job. I promise do double check next time before recording ;-)!
