Please help! JVC A-X9 Integrated Amp

Looking for advice....have what appears to be a new JVC A-X9 w/o any manuals. Problem...it's a euro unit 50Hz, 220V. It is the model with the multi-voltage switch (110V,120V,220V,240V) and the supplied fuse is the one for 220/240V (T3.15A/250V).
What do I need to do before plugging in this unit in California? Or is that even possible?

Thanks for your help!
