The power requirement is 120V AC, 60Hz for USA/Canadian models, 240V AC, 50
Hz for UK/Australian models, and 220V AC, 50Hz for European models, out of
a regulated power supply.

NOTE:  Nominal specs represent the design specs; all units should be able 
       to approximate these - some will exceed and some may drop slightly 
       below these specs.  Limit specs represent the absolute worst 
       condition which still might be considered acceptable; in no case 
       should a unit perform to less than within any limit spec.
