INTRODUCTION

ListenTALK is a portable wireless collaboration system designed for group communications in
a variety of applications including Training and Collaboration, Assistive Listening, Guided Tour
Groups, Language Interpretation and Translation, Event Production and Sports Intercom.

SIMPLE AND VERSATILE

ListenTALK systems are simple to purchase and congure 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 as many as ten simultaneous groups in the same area.

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.

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!

LISTENTALK DEFINITIONS

ListenTALK Group

A ListenTALK Group is two or more ListenTALK units which have been Paired.

Pairing

Pairing is the process whereby ListenTALK units become a group. ListenTALK units may be paired by NFC
(Near-Field Communications), with a Docking Station or with the ListenTALK Software Suite.

5

Leader, Sub-Leader and Participant

A Group consists of one Leader, one or more Sub-Leaders (optional) and one or more Participants.
In a museum tour, the museum guide would be the Leader, an assistant guide would be the Sub-Leader

and the museum guests would be Participants.

ListenTALK Security

Conversations within a ListenTALK Group are encrypted by a unique Pair Key which separates Groups
from one another and ensures secure conversations within each Group. The Pair Key is generated by the
Group’s Leader and shared with each Sub-Leader and Participant (see Page 25).
