Effective Range
100 m (300 ft.) under optimal conditions
NOTE:
Actual working range depends on RF signal absorption, refl ection, and interference
Audio Frequency Response
25 to 15,000 Hz, ±2 dB
NOTE:
Overall system frequency response depends on the microphone element.
Transmitter Audio Polarity
Positive pressure on microphone diaphragm (or positive voltage applied to tip of WA302 phone plug) produces positive volt-
