Note: With volume control in maximum position, connect signal generator to telescopic antenna input terminal (through suitable impedance matching network). Standard output level is 50 mW at 8 Ohm (resistive load). Note: Nominal specs represent the design specs. All units should be able to approximate these - some will exceed and some might drop slightly below these specs. Limit specs represent the absolute worst condition that still might be considered acceptable; in no case should a unit fail to meet limit specs. (br/all-12/28/94)
