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

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.

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.

ListenTALK Graphic Displays will show ListenTALK Transceiver ID, Group name, Group number,
battery status, signal strength and other information.
LISTENTALK ADVANCED FEATURES
Using Multiple ListenTALK Groups
Each ListenTALK Group operates on its own communications channel. You may create an unlimited
number of ListenTALK Groups and up to ten Groups may operate without interference within a
given area. ListenTALK Groups have one Group Leader and an unlimited number of Sub-Leaders
and Participants. Communication within a Group is encrypted by a unique Pair Key making
ListenTALK an ideal choice for facilities that need secure communications for simultaneous
translation, tour-guide use and other applications. Please see “ListenTALK Security” on Page 18 for
more information.
Charging and Battery Replacement
Rechargeable ListenTALK Transceivers may be charged in the Docking Station. To charge an individual
Transceiver, connect a USB charger to its Micro USB port.
To replace batteries on a non-rechargeable Transceiver, depress the button on the battery door and slide the
battery door downwards. Insert three AAA size alkaline batteries.
Updating ListenTALK Firmware
ListenTALK Transceiver rmware updates are available through the ListenTALK Software Suite.
LISTENTALK SOFTWARE SUITE
The ListenTALK Software Suite allows a Windows computer to program a ListenTALK system and check
ListenTALK status. After installation, the software will automatically connect to any Docking Station or
individual Transceiver connected to the computer’s USB port.
ListenTALK Software Suite features include complete setup, inventory management, group creation and
naming. The suite includes an extensive help le.

LISTENTALK APPLICATIONS
Tour Guide System
A ListenTALK System is ideal for use as a museum, factory or other facility tour-guide system. Create a
ListenTALK Group as described on Page 15. Press and release the Leader’s Talk Button to toggle between Talk
and Mute. Press and hold a Participant Talk Button to talk to the Leader or Group as dened by the Leader’s
choice of Talkback Modes (see Page 17).
Tour Guide System with Leader and Sub-Leader
A second ListenTALK Leader, known as a Sub-Leader, is useful for two-instructor tours, classrooms or any
application where a second Leader will accompany a group and speak to all Group members. Insert a red
Leader Clip onto a Transceiver and Pair it to the Leader (see Page 15) to create a Sub-Leader. The Leader
controls the Group name, Pair Key and Talkback Modes. The Sub-Leader Talk Button toggles between Talk and
Mute modes. 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.
Training and Collaboration
A ListenTALK System with multiple Sub-Leaders is ideal for training in a corporate or sports setting.
Choose a noise-cancelling, microphone-equipped headset when needed for noisy environments and
set the ListenTALK System Talkback Mode as desired to restrict or enable talkback from Sub-Leaders and
Participants (see Page 17).
Simultaneous Translation
It may be desirable to create two, separate ListenTALK Groups so that Participants speaking one language
are not confused by translation into a second language. For this application, create two separate ListenTALK
23
Groups in a normal manner as described on Page 15. The ListenTALK Software Suite allows Groups to have
descriptive names such as “English” and “Spanish”.
Wireless Intercom
Two or more ListenTALK Transceivers may be used as 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. Create a ListenTALK Group with one Transceiver as Leader
and the other Transceivers as Sub-Leaders to enable hands-o, full-duplex conversations.
The Talk Button on a Leader or Sub-Leader is a toggle – touch once to talk; touch again to mute. This allows
a Leader and a Sub-Leader to hold a hands-o, full-duplex conversation (both in Talk Mode). If a second
Sub-Leader presses their Talk Button, they take over the conversation and the rst Sub-Leader automatically
mutes. Multiple Sub-Leaders can hold a conversation with the Leader in this manner while other Sub-Leaders
listen. To enable this capability, the Leader must choose “Group Mode” using their Left Soft Button. Also see
“Operation with Leader and Sub-Leader” on Page 17.
LISTENTALK SYSTEM TROUBLESHOOTING
The ListenTALK Has No Power
Make sure the ListenTALK has a fully charged battery or is connected to a standard USB charger. Make sure
the Power Button on the top of the Transceiver has been pressed to turn the Transceiver ON. If this does not
work, make sure the battery is installed properly and/or install a replacement battery.
There is No Audio
Check that the ListenTALK is on the same Group with other Participants and the Leader. Make sure the
Volume Control is turned up to at least 25%. Conrm that the headset is plugged in all of the way.
Audio is Distorted
Verify the audio on the transmitter is not turned up too loud; this will cause distortion. Insure the headset
connectors are pushed all the way into the Headset/Microphone Port on top of the Transceiver.
Try a dierent headset.
I Cannot Pick Up the Signal on My ListenTALK
Check to make sure the ListenTALK Leader and Participants are members of the same group.
I Can Pick up the Signal on the ListenTALK, but it Sounds like it’s not Tuned in.
Check the ListenTALK Leader and Participant and conrm members of the same group and
move closer to the Leader.
My Battery is Not Charging (Rechargeable ListenTALK Transceivers).
Verify the clear plastic pull tab has been removed from the ListenTALK battery door engaging the battery
connections. Make sure the battery is installed properly and that the Transceiver is fully inserted into the
Docking Station pocket. If using a USB charger, try another USB cable. Check the charging device to verify
it is plugged in the proper power outlet and power is available at the outlet. If this does not work, install a
replacement battery.
I Want to Run the ListenTALK Transceiver from a USB Charger
Simply plug any standard USB charger into the Micro USB connector on the side of the ListenTALK Transceiver.
