* European models must not be able to tune below 87.5 MHz.

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.
