OTTO Wireless Ear Receivers make OTTO your Two and Three Wire kits perfectly covert. The Wireless Ear Receiver fits securely in your ear canal. It is comfortable and almost invisible. Used in conjunction with either the OTTO Flat Pack Inductor or Neck Loop style Inductor to create the invisible inductive field that transmits the radio’s sound to the Wireless Ear Receiver. Wireless receivers are available in squelch and non-squelch versions, the squelch version contains squelch circuitry that mutes the amplifier during periods when no signal (i.e. radio receive) is present. This feature removes the “hiss” which is present in conventional wireless earpieces and its absence should not be treated as a fault. In use, care should be taken to ensure the radio inductor assembly is correctly positioned on the body and in addition, the receive volume control is adjusted to the required level. All models are shipped as a kit including carrying pouch, four A10 batteries, fifteen wax filters, and one wax filter tool Menu>Features: Wireless Receiver can be used with either the Neck Loop or Flat Pack Flat Pack allows wireless receive transmission when used with a Wireless receiver Specifications Measurement Conditions Ambient Temperature 25CSupply Voltage 1.4 VDC Frequency Range -6dB 300 - 5000Hz IEC 118-1 Operating Temperature -10C to +40C CE Conformity 89/336/EWG-Electromagnetic Compatibility Testing Method for Devices with Inductive Inputs Distortion 2% AGC Attack < 0.5 secondsAGC Release > 0.5 seconds Total Harmonic Distortion 105 dB @ 10% distortion < 3% 500-5000HZ Battery 1.4 VDC A10 Zinc Air or Equivalent Consumption Gate open gate closed > 100 hours depending on use Sensitivity 78dB at 2kHZ-20mA/M Amplifier Customized hybrid Weight 1.5 grams(incl.
