DESCRIPTION The Companion MicsTM system was developed for persons who have significant difficulty understanding conversation in background noise such as restaurants and public places. This system enables one, two or three talkers (four on special order) to speak to a single listener.
• Adjust the volume control after all Talker Units are on. The Listener should be able to hear each Talker clearly, as if the Talkers were speaking into the Listener’s ear. Instructions for Talkers: • Place Talker Units (identified by a black clasp on neck cord) around the neck and adjust the cord so the unit rests comfortably just under the chin. VOLUME CONTROL (Up/Down Switch) The overall volume is adjusted on the Listener Unit only.
3. Turn the Listener Unit back on by pressing the button for 1-2 seconds. The units should reconnect in 8 seconds or less. OPERATING DISTANCE Under line-of-sight conditions out in the open, the units may operate over a distance of 150 feet or more. Indoors, where there are reflections, the units should maintain communication over a distance of 15 to 20 feet even if the Listener and Talkers occasionally turn their backs to each other. 5 BATTERY CHARGING To recharge, place units in the Charging Case.
sequence of frequency hops while each Talker Unit waits for one or another of those frequencies until it receives a transmission containing the identification code from the Listener Unit. The units then lock together jumping from frequency to frequency. This process is repeated until all Talker Units lock on. Once all units are in communication with each other, the LED lights stop blinking and the Talkers are heard by the Listener.
