OmniSound®HD – superior sound quality
The patented OmniSound®audio technology guarantees an impressive and crystal-clear
full-duplex audio, allowing you to speak in two directions for effective participation in
virtual meetings. The sound is transmitted clearly and powerfully to all attendees thanks
to a hypersensitive microphone with 360° audio pick-up and speakers.
OmniSound®HD delivers HD audio during VoIP calls. It also incorporates automatic echo
cancellation and noise suppression, which minimises background noise interference, and
an equaliser for personal adaptation of the audio properties. This means you can move
about freely in the room, talking, discussing and debating with others without any loss of
audio quality and without any annoying sound clipping, damping or echoes. It's as close to
real sound as you can get.
Konftel AB hereby declares that this conference phone is in conformity with all the essen-
tial requirements and other relevant provisions of Directive 1999/5/EC.
Please visit www.konftel.com/doc to read the declaration in its entirety.

The Konftel 55W is a conference unit that can be connected to your desktop phone, your
mobile phone and your computer to obtain crystal-clear, powerful OmniSound®HD audio
in your virtual meetings.
• OmniSound®HD audio technology with full duplex, echo cancellation and static reduc-
tion in full bandwidth (20–24000Hz). (The telecommunications network technology
limits the bandwidth when communicating via the telecommunications network.)
• Support for UC solutions, such as Microsoft®Lync®.
• LCD high-resolution display with touch buttons, where the interface changes according
to the connections you make.
• Mobile phone connection via a mobile cable (accessory) or Bluetooth.
• Connection to a desktop phone via a Konftel desk phone adapter (accessory) which
makes it easy to move the sound between the handset and conference phone.
• USB connection to a computer or another USB device that supports handsfree
connection.
• Automatic detection of USB playback/VoIP calls, which means that the OmniSound®
HD audio processing feature only processes the sound when necessary. The sound is
not altered when music is played.
• Audio bridge capability between a computer and connected phone.
• Call recorder capability allows you to listen to meetings afterwards or use the Konftel
55W as a dictaphone.
• Battery-powered option, which makes the Konftel 55W completely cordless with a
Bluetooth-connected phone.
• The battery can be charged via the mains supply (power adapter provided) and USB.
• Headset connectivity option allows easy switching between headset and speaker func-
tion.
• Expansion microphones can be added to increase the voice pickup range. (Optional
accessory.)
• Upgradeable.
• Two-year warranty.
MAINTENANCE
Clean the equipment with a soft, dry cloth. Never use liquids.

DESCRIPTION
GENERAL
The Konftel 55W automatically detects the connections you make. Despite the unit's
multiple connectivity options, it is simple to use and understand because it only displays
the buttons that can be used in that particular situation.
The first time the Konftel 55W is started up, the display only shows a menu button and
a Bluetooth button ( ) which is used for pairing and connecting to a mobile phone. If you
connect to a computer via USB, a button for this is displayed so that you can easily turn
the sound on and off. Similarly, a desktop button is displayed if you connect a desktop
phone, a headset button if you connect a headset and a record button if you insert an SD
memory card.
A lit button indicates that the feature is active. When you press the button, it switches
between on and off.
Support for UC solutions
The Konftel 55W has expanded support for UC solutions, such
as Microsoft®Lync®. Visit www.konftel.com for more informa-
tion.
LEDs
When a mobile or desktop phone button is activated, the blue
LEDs light up too, indicating that an audio channel is open.
This does not necessarily mean that a call is in progress since
the call is controlled from the connected device (the mobile or
desktop phone).

DESCRIPTION
You can move the sound between the Konftel 55W and the phone during a call by
pressing the button ( or ) on the Konftel 55W.
With a computer connection, the LEDs first light up when a communication program that
uses the microphone starts.
With a Bluetooth connection, the blue LEDs first light up when a call is connected. Since
the connection allows communication in addition to the sound, a phone call can be initi-
ated from the Konftel 55W keypad.
Mute button
Press the button (the actual button on the right) to turn the microphone off during
a call.
The LEDs show a steady red light and two buttons are displayed.
Press the button if you also want to turn the speaker off.
The LEDs flash red.
Note that the buttons on the screen disappear after 5 seconds or if you touch the
screen outside the buttons.
Press once again (the actual button on the right or the button on the screen) to turn
the microphone (and speaker) on.
The LEDs show a steady blue light.
Power save mode
The Konftel 55W has several power save mode levels. After five minutes, the background
lighting fades and after 15 minutes the image on the screen is replaced by a clock. Less
time if running on battery power.
Switching off
Hold down the button (the actual button on the left) for three seconds.
Confirm that you want to switch off the Konftel 55W by pressing .

DESCRIPTION
BRIDGE CONNECTION
It is possible to establish an audio bridge between a connected phone and the computer.
This means that you can make a call with your connected mobile or desktop phone and
combine it with, for example, a Skype®call on the computer.
Audio bridge combinations other than a phone and computer are not possible.
Find out more about audio bridging on page 24.
BATTERY
The battery is charged in the Konftel 55W, either via the power adapter provided or via
USB. It takes about 4 hours to fully charge an empty battery using the power adapter and
about 5 hours via USB.
The Konftel 55W has to be connected to a USB port that produces power (e.g. on a
computer) in order to charge the battery. Note that it takes much longer to charge via
USB if the Konftel 55W is turned off.
Inserting a battery
Push the battery cover forwards to remove it.
Insert the battery in the Konftel 55W with its contacts towards the pins in the bottom
of the battery compartment.
Slide the battery cover back into place.

The Konftel 55W transforms your desktop phone to a conference phone with OmniSound®
HD. Unlike the integrated speaker function of many desktop phones, you enjoy a high
sound level, full duplex (two-way audio) and efficient echo cancellation and noise reduc-
tion.
OmniSound®HD performs over the full audio bandwidth (100–24000 Hz) but the
technologies in today's telecommunications networks do not allow the full bandwidth
to be used. This has an effect on the sound quality.
The Konftel 55W is connected using a desk phone adapter (accessory) which is installed
between the phone and handset. The adapter allows you to transfer calls between the
Konftel 55W and the handset by pressing a button.
The Konftel 55W can be connected to all digital phones (corporate networks) and, in
many cases, to analogue phones too (traditional telephone sockets in the home).
Note that some desktop phones can also be connected via their headset jack. See
"Using the Konftel with a mobile phone" on page 9.
CONNECTING TO A DESKTOP PHONE
Unplug the telephone handset cable from the phone and connect it to the desk phone
adapter.
Connect the desk phone adapter to the phone and the Konftel 55W as illustrated below.
The button is displayed on the Konftel 55W.
Make a test call to check that the receiving party has a good sound level (see page 32).
The sound level produced by phones varies between the different makes. The Konftel
55W's microphone level may therefore need adjusting to ensure good sound quality for
the other call participants. The setting is saved in the Konftel 55W and is used each
time a phone is connected via the adapter.

MAKING CALLS
You can make a call with the phone as usual and then transfer the call to the Konftel
55W, or transfer the sound before the call is connected.
Press the button on the Konftel 55W to transfer the sound from the phone to the
Konftel 55W.
The button and the LEDs light up.
Lift the handset and dial the number on the desktop phone.
Adjusting the volume
The volume can be adjusted when the phone is active ( is lit up). As is the practice
in the context of telephone communications, it is not possible to turn the sound off
completely using the volume control.
Transferring and ending calls
Press to transfer the sound between the Konftel 55W and the phone's handset.
End the call by placing the handset back on the desktop phone.
The button on the Konftel 55W can remain lit if you want to use the Konftel 55W
for future calls too.
