The ListenTALK GR8 System is designed for portable wireless one-way communications with one leader and seven participants. Easy set up via software, Charging Case or Near Field Communications (NFC). Excellent for tours, simultaneous interpretation, training, etc. The system operates on the 1.9 GHz unlicensed PCS band utilizing Frequency-Hopping Spread Spectrum (FHSS) techniques allowing interference free one-way communication. The units are easy to pair and form groups via near-field communication (NFC) by touching the backs together, or using the docking station or software suite. The transceivers and receivers are powered by a removable non-proprietary rechargeable lithium-ion battery or the optional 3 AAA alkaline battery compartment. The devices have a 64 x 128 OLED display with auto dimming allowing display of all current status (group name, volume levels, mute, battery status, time remaining, signal strength, unit ID, mode, etc.) The Leader device has a leader clip and when inserted the unit automatically designates itself as a leader and allows the leader/presenter to control pairing/group creation. The devices incorporate automatic battery charging circuitry to charge and maintain the lithium-Ion battery either via the micro USB port or via the docking station using the additional charging contacts on the bottom of the devices.
