3System overview
The Wireless headset system consists of three main products. Clave Base, Clave DECT Headset(s) (refer to
11. Appendix A
for different models) and Clave DECT Dongle.
The high-end headsets support DECT and BT technology to establish connection with other devices. They
are used with the Clave Base and desk phone / PC / laptop/ mobile phones. The selected microphone is
balanced together with the headset filters to reduce the background noise to provide an ultimate
understandable and clear speech. On the other hand, the receivers are balanced to the receiver housing
and cushion, so the headset will provide the user an excellent stereo experience.
The figure below (
Fig.1)
illustrates the high-level description of the system. It provides the basic
understanding of the environment in which the device needs to interact. Both communication possibilities
of the Clave are presented in the drawing below and further defined in the following sections.
Fig.1 System overview
3.1 Soft client support
The Clave Base provides support for various soft clients and thus, it can be used with both PC Windows and
MacOS. This means that, the base combined with one of the Clave Headsets, supports the audio and USB
API of the applications, such as:
•Microsoft Teams
•Customer client support implemented in PC tool
Respectively, if the headset is used in standalone mode over a Bluetooth™connection, the audio of the
same applications (and more) will be supported. In addition to this, the devices can also be used as
generic USB headsets for general audio.
Page 10 of 54
3.2 Handover to VoIP multicell systems
The Clave Headset and Clave Base can be integrated together into VoIP multicell and dual cell systems. The
headset base will register on behalf of itself and the headset. The two registrations are independent but
will be linked logically as one unit on the VoIP system. The purpose of this integration is to hand over the
user’s calls to the VoIP system for the user to be flexible in terms of location
(Fig.2).
Fig.2 Call Handover
3.3 Clave DECT Dongle
The Clave Headset can be used with the Clave DECT Dongle, which will serve as a base station. This is
convenient for users who want to use the headset remotely, for example in home office or on the road
where it is not possible to bring the base station
(Fig.3)
. The dongle is supported by both Windows and
MacOS.
Fig.3 Headset connection via Clave DECT Dongle

4Clave wireless DECT headset overview
The Clave series are wireless DECT + Bluetooth™headsets. As mentioned before, the headset connects to
the DECT base, which act as a charger for the headset, via the DECT wireless technology. It can also connect
via Bluetooth™to supported devices, such as mobile phones and Bluetooth™compatible desk phones.
A Busy-light indicator on the headband is used to indicate that the user is busy. The headset also features
Environmental Noise Cancellation (ENC) to suppress unwanted environmental noise for the microphone
input and Active Noise Cancellation (ANC) to suppress the noise towards the user. The headset offers DSP
assisted echo cancelling. The length of the headband is adjustable to suit the head-shape of different users
and the tilting angle of the boom can be adjusted to fit the position of the mouth of different people.
The DECT base/charger connects to the PC/laptop. It can access Microsoft Teams and a defined range of
soft call clients from external vendors, as well as a defined range of desk phones via EHS interface. Call
control can be managed via the base, attached desk phones, soft call clients on the PC or via the buttons
on the left earcup of the headset. A conferencing feature allows up to 4 headsets to connect to the same
base –users may be added / removed from the conferencing call on the fly.
The primary application of the Clave is within call centers and office environments allowing the user to
access the internet/VoIP calls and music playback via the PC/BT.
4.1 Type of Clave Headsets
The headset auto-configures the DECT setup when connecting to the base, thus no country specific variants
exist. As mentioned earlier, the Clave series covers 3 different headsets: (For more detailed features

Page 14 of 54
The headset has 7 different control buttons
(Fig.8).
Fig.8 Buttons and user interface.
The images below represent the styling of the headsets from the Clave series
(Fig.9)
. The product is
available in 3 different colors –grey, black and white. The cushions of the headsets are removable and
replaceable to improve the comfort of the users.
There are two types of ear cushions –on-ear and over-the-ear
(Fig.9).
Clave Duo ANC supports both types
of ear cushions. A sensor in the headset detects which type of cushion is used and adapts the audio
tuning accordingly to get the optimal noise reduction. The other two devices (Clave Mono NC and Clave
Duo NC) only support the on-ear cushion solution.

6Clave DECT Dongle overview
The Clave DECT is a USB type A dongle with slide switch that can establish a wireless connection with the
UH headsets from the Clave series. The dongle supports dual mode, meaning that it can be used either as
a Fixed part (FP), or Portable part (PP).
-Base / FP mode:
oActs as a DECT base for the Clave Headsets
-Headset / PP mode:
oEnables DECT access for a USB desktop phone on the UH VoIP system
Since the DECT dongle can run one mode at a time, you can switch between the two functionalities by
using the slider switch.
The device is designed to be easy to use with a desk phone/PC/laptop with very good sound quality. Since
the device uses DECT technology, it can remember 4 registrations –one primary and three secondaries.
The audio can be directed to the headset, depending on the user’s choice. When the headset is
connected via the Clave DECT Dongle to a PC, the user may access calls from Soft Call Clients, such as
Microsoft Teams. Support for other call clients is available and requires that the PC Setup tool is installed
on the used laptop/PC.
