Consumer Alert - Most users do not need a license to operate this wireless
microphone system. Nevertheless, operating this microphone system without a license
is subject to certain restrictions: the system may not cause harmful interference;
it must operate at a low power level (not in excess of 50 milliwatts); and it has
no protection from interference received from any other device. Purchasers should
also be aware that the FCC is currently evaluating use of wireless microphone systems,
and these rules are subject to change. For more information, call the FCC at 1-888-CALL-FCC
(TTY: 1-888-TELL-FCC) or visit the FCC�s wireless microphone website at http://www.fcc.gov/cgb/wirelessmicrophones.

- RF Carrier Frequency Range: 554.000 to 865.000 MHz
Effective Range: 100 m (300 ft.) under optimal conditions (Actual working range depends on RF signal absorption, reflection, and interference)
Audio Frequency Response: 25 to 15,000 Hz, (±2 dB (Overall system frequency response depends on the microphone element) *Output Level: Microphone Level = Line Level — 20 dB
Transmitter Audio Polarity: Positive pressure on microphone diaphragm (or positive voltage applied to tip of WA302 phone plug) produces positive voltage on pin 2 (with respect to pin 3 of low impedance output) and the tip of the high impedance 1/4-inch output
Receiver Audio Output Level (±38 kHz deviation, 1 kHz tone)
XLR connector (into 600 ohm load): +3.9 dBV (line), —17 dBV (mic); 1/4 inch connector (into 3000 ohm load): —2 dBV
Impedance (output): 50 ohms at line level; 2000 ohms at mic level
Modulation: ±38 kHz deviation compressor-expander system with pre- and de-emphasis.
Dynamic Range: >100 dB, A-weighted

Image Rejection: 80 dB typical
Spurious Rejection: 75 dB typical
Ultimate Quieting (reference ±38 kHz deviation)
>105 dB, A-weighted
System Distortion (reference ±38 kHz deviation, 1 kHz modulation): 0.3% total harmonic distortion, typical
Power Requirements: - 18 Vdc (negative ground), 550 mA
Battery Life: 8 to 9 hours (with 9V Duracell MN1604 alkaline battery)
Operating Temperature Range: -20 degrees to 49 degrees C (—4 degrees to 120 degrees F) NOTE: Battery characteristics may limit this range.
