ListenTALK USER MANUAL
INTRODUCTION
ListenTALK (LK-1, LKR-11, LKR12) and their accessories have been designed as a mobile
or stationary, one or two-way, wireless collaboration system designed for group
communications in a variety of applications. This includes applications such as Training
and Collaboration, Assistive Listening, Guided Tour Groups, Language Interpretation and
Translation, Event Production and Intercom. This product can be used for residential or
commercial purposes.
SIMPLE AND VERSATILE
ListenTALK systems are simple to purchase and congure and they are highly versatile.
Create a ListenTALK Group with the push of a button in the Docking Station, with the click of a
mouse in the ListenTALK Software Suite or on the go using built-in Near Field Communication
(NFC) technology. Use up to twenty simultaneous groups in the same area for North America
(A0) and Japan (J0) versions and up to thirty groups in the same area for the Europe (E0)
version.
ListenTALK Transceivers are simple to operate and leaders can easily designate one of three
Participant modes to meet the needs of any venue or application.
RELIABLE AND SECURE
Instead of the overcrowded 2.4 GHz frequency, ListenTALK operates on the 1.9 GHz band
in full duplex and utilizes frequency hopping and spread spectrum technology to increase
reliability and reduce interference. Headset styles are available for use in quiet or noisy
environments, or simply use your own.
Listen understands that your security matters, so each ListenTALK is equipped with a
multilayer security protocol consisting of a 40-bit (pin free) group subscription, 32-bit
authentication and a 64-bit encryption scheme assuring secure conversations.
WELCOME TO LISTENTALK!
ListenTALK is Simple, Versatile, Scalable, Secure and Reliable!
