iMac only makes repetitive start up tones, Unit is in Hungary, can an imac use 120v - 240 volts

I have a customer who claims his newly delivered iMac ,which by the way ,is in Hungary only makes repetitive, startup tones, He sent me a phone video of the imac it has ablack screen and only repeats the startup tones, unit was working flawlessly when I had it running here!! Anyone have any ideas?? He had a wireless mouse and keyboard we tried a wired pc keyboard to reset SMC and P-ram to nothing but the same symptom, which also made me wonder about if the iMac has an auto switching power supply??? Ugh!! Please help if you can!!

iMac (21.5-inch Mid 2011), OS X El Capitan (10.11.1)
