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 COMPONENTS
LISTENTALK DEFINITIONS
ListenTALK Group
A ListenTALK Group is two or more ListenTALK Transceivers which have been Paired.
Pairing
Pairing is the process whereby ListenTALK Transceivers become a group. ListenTALK Transceivers may be
paired by NFC (Near-Field Communications), with a Docking Station or with the ListenTALK Software Suite.
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 18).
ListenTALK Transceiver LK-1
The term ListenTALK refers to the system as a whole and to the hand-held
ListenTALK Transceivers.
Docking Station 16 Tray
The optional ListenTALK Docking Station 16 serves as convenient storage, programming
and charging station for ListenTALK Transceivers. The Docking Station makes it easy to
create a ListenTALK Group and perform other tasks.
Docking Station Case 16
The optional ListenTALK Docking Station Case serves as convenient storage,
programming and charging station and portable carrying case for ListenTALK
Transceivers. The Docking Station Case provides all of the features of the
Docking Station 16 Tray.

Participant Buttons
Press and hold the Talk Button to speak. Release to mute. Participant can speak to the entire Group or only to
the Leader depending on the Talkback Mode set by the Leader (see Page 17). The Participant Talk Button does
not function when the Leader chooses “O” mode. Only one Participant can speak at a time. Soft Buttons are
disabled on Participant Transceivers.
Leader Buttons
Press and release the Talk Button to toggle between Talk and Mute. It is not necessary to hold down the
Leader’s Talk Button. The Leader congures ListenTALK Talkback Modes as described on Page 17. The Leader
also controls Group Pairing and passes the Group Name and Pair Key to Sub-Leaders and Participants.
Sub-Leader Buttons
The Sub-Leader’s Talk Button operates like that on a Leader. A Sub-Leader can Pair new Sub-Leaders and
Participants making them members of a Group. In so doing, the Sub-Leader passes on the Group Name and
Pair Key from the Leader.

Operation with Leader and Sub-Leader
ListenTALK Groups have one Group Leader and an unlimited number of Sub-Leaders and Participants.
A single Sub-Leader is useful for classes with dual instructors or tour groups led by more than one
person. A Group with one Leader and multiple Sub-Leaders is a versatile wireless intercom for event
production, sporting activities and training sessions and it can facilitate workgroup collaboration in
warehouses, manufacturing environments or construction sites. Sub-Leaders can Pair with new Sub-
Leaders or Participants, making them members of a Group and passing the Group name and Pair Key
from the Leader. Also see Applications on Page 22.

18
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. When Sub-Leaders add new Transceivers to a
Group, they pass the Leader’s Pair key to these new group members.
ListenTALK Pair Key security may be congured with the ListenTALK Software Suite or through the
Leader’s New Pair Key menu choices as described next.
Never – Normal Security (Default)
By this (default) choice the Pair Key never changes within a Group. This enables secure communication
within a Group while allowing unrestricted Group expansion and is a good choice for venues like museums
where the number of Participants may vary from tour to tour.
8 Hours, 4 Hours or 1 Hour – High Security
By this choice, the existing Pair Key is maintained when expanding a Group within the chosen time window.
After the time window expires, the Leader will generate a new Pair Key when it Pairs with a Sub-Leader or
Participant making them part of a new Group. This enables expansion of an existing Group but only
within the chosen time window.
Always – Highest Security
By this choice, the Leader will always generate a new Pair Key when it Pairs with a Sub-Leader or
Participant making them part of a new Group. This disables the expansion of an existing group
and is a good choice for high-security venues.
Resetting a Group’s Pair Key
It is possible to reset a Group’s Pair Key without changing the Group Name. This may be useful when a
Transceiver is misplaced and you want to exclude that Transceiver from the Group thereby preventing
it from listening to or taking part in conversations.
To reset the Pair Key for a ListenTALK Group, place the Leader, Sub-Leader(s) and Participants into their
respective Docking Station pockets. Then, press and hold the Docking Station Pairing Button for ve seconds.
The Paring Indicator and Status Indicators will ash momentarily and then turn solid indicating success.
The ListenTALK Software Suite can also implement this process.
To reset the Pair Key for a ListenTALK Group without a Docking Station, set the Leader’s New Pair
Key menu choice to “Always”. Then, repeat the Near Field Communication pairing operation for all
Transceivers in a Group.
Note that the Docking Station and Software Suite force a New Pair Key without regard to the
Leader’s New Pair Key menu choice.
LISTENTALK TRANSCEIVER PROGRAMMING
ListenTALK Transceivers may be programmed by placing them in the Docking Station and connecting
the Docking Station USB Port to a Windows computer equipped with the ListenTALK Software Suite. An
individual ListenTALK Transceiver may be programmed by connecting its Micro USB to the USB port on a
Windows computer equipped with the ListenTALK Software Suite. An individual ListenTALK Transceiver
may be programmed by pressing specic buttons on the Transceiver while monitoring its Graphic Display.

LISTENTALK DOCKING STATION OPERATION (SEE PAGES 9 - 10)
The ListenTALK Docking Station operates as a charger and programming station and provides convenient
storage for ListenTALK Transceivers. Mount the Docking Station on a at surface. Connect the Power Supply to
the Docking Station and to any standard AC outlet (100/240 VAC, 50/60 Hz). Place ListenTALK Transceivers into
the Leader and Participant Pockets to charge and program the Transceivers.
Creating a ListenTALK Group with the Docking Station
To create a Leader, or Sub-Leader snap a red Leader Clip onto any Transceiver. Omit the Leader Clip from
Participant ListenTALKs. Place the Leader in the Docking Station’s red Leader Pocket. Place Sub-Leader(s) and
Participants in the Docking Station’s black Participant Pockets.
To create a Group, Pair the Leader with Sub-Leader(s) and Participants by pressing the Pairing Button
momentarily on the Docking Station. The Pairing Indicator will ash during pairing, then turn solid and nally
extinguish when the pairing process is completed.
