OmniSound® – 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® 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 essential requirements and other relevant provisions of Directive 1999/5/EC.

DESCRIPTION
GENERAL
The Konftel 55Wx 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 55Wx 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 55Wx has expanded support for UC solutions, such
as Microsoft® Lync®. Visit www.konftel.com for more information.
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
On / Off (long press) Mute (microphone off / speaker off)
LEDs
You can move the sound between the Konftel 55Wx and the phone during a call by
pressing the button ( or ) on the Konftel 55Wx.
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 initiated from the Konftel 55Wx 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 55Wx 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 55Wx 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 28.
BAT TERY
The battery is charged in the Konftel 55Wx, 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 55Wx 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 55Wx is turned off.
Inserting a battery
Push the battery cover forwards to remove it.
Insert the battery in the Konftel 55Wx with its contacts towards the pins in the bottom
of the battery compartment.
Slide the battery cover back into place.

USING THE KONFTEL WITH A DESKTOP PHONE
The Konftel 55Wx transforms your desktop phone to a conference phone with
OmniSound®. 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
reduction.
OmniSound® performs over the full audio bandwidth (100–24000 Hz) but the tech-
nologies in today's telecommunications networks do not allow the full bandwidth to be
used. This has an effect on the sound quality.
The Konftel 55Wx 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 55Wx and the handset by pressing a button.
The Konftel 55Wx 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 55Wx as illustrated below.
The button is displayed on the Konftel 55Wx.
Make a test call to check that the receiving party has a good sound level (see page 36).
The sound level produced by phones varies between the different makes. The Konftel
55Wx's microphone level may therefore need adjusting to ensure good sound quality
for the other call participants. The setting is saved in the Konftel 55Wx and is used
each time a phone is connected via the adapter.

USING THE KONFTEL WITH A DESKTOP PHONE
MAKING CALLS
You can make a call with the phone as usual and then transfer the call to the Konftel
55Wx, or transfer the sound before the call is connected.
Press the button on the Konftel 55Wx to transfer the sound from the phone to the
Konftel 55Wx.
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 55Wx and the phone's handset.
End the call by placing the handset back on the desktop phone.
The button on the Konftel 55Wx can remain lit if you want to use the Konftel 55Wx
for future calls too.

USING THE KONFTEL WITH A MOBILE PHONE
The Konftel 55Wx transforms your mobile phone to a conference phone with OmniSound®,
ensuring high sound level, full duplex (two-way audio) and efficient echo cancellation and
noise reduction.
OmniSound® performs over the full audio bandwidth (100–24000 Hz), but limitations
in mobile telecommunications networks reduce the bandwidth somewhat and the
sound is compressed. This has an effect on the sound quality. Calls via updated 3G
networks are more likely to have good audio quality.
Note that it is not possible to use a desktop phone and a mobile phone at the same
time with the Konftel 55Wx. The desktop phone connection is disabled when the
mobile phone is connected.
CABLE CONNECTION TO A MOBILE PHONE
The Konftel 55Wx is connected using a cable which is adapted for your phone (optional
accessory). The Konftel 55Wx works in the same way as a headset connected to the
mobile phone.
Note that some desktop phones can also be connected via their headset jack. The
function is exactly the same as for a mobile phone connection and we only write
"mobile phone" in the description.
Connect the phone to the Konftel 55Wx using the mobile phone cable.
The button is displayed on the Konftel 55Wx. The button is immediately activated on connection.
Make a test call to check that the receiving party has a good sound level. See page 36.
The sound level produced by phones varies between the different makes. The Konftel
55Wx's microphone level may therefore need adjusting to ensure good sound quality
for the other call participants. The setting is saved in the Konftel 55Wx and is used
each time a phone is connected via a mobile cable.
Automatic detection of mobile phone
The Konftel 55Wx can normally detect when a mobile phone is connected via a cable.
Some mobile phones do not activate the connection until a call is connected or they put
the connection to the Konftel 55Wx/headset to sleep after a certain period of inactivity. If
this is the case, the button will not be displayed until you make a call from your mobile
or receive an incoming call.
If you want ( ) to be visible all the time and your mobile phone does not automatically
activate the connection, you can change the setting so that the button is always displayed,
whether or not your mobile phone is connected (see page 35).

USING THE KONFTEL WITH A MOBILE PHONE
MAKING CALLS
Check that the button on the Konftel 55Wx is lit up blue. If it is not lit up, press the
button.
Dial the number on the mobile phone.
If you have a call in progress on your mobile and want to transfer it to the Konftel
55Wx, simply connect the cable.
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.
Hold
Press to put the call on hold (microphone and speaker turned off).
Transferring calls
Remove the cable from the mobile phone to transfer the sound from the Konftel 55Wx
to the phone.
Ending calls
End the call on the mobile phone.
The button on the Konftel 55Wx can remain lit if you want to use the Konftel 55Wx
for future calls too.
10
USING THE KONFTEL WITH A COMPUTER
The Konftel 55Wx transforms your computer to teleconferencing equipment with
OmniSound®. Unlike normal computer speakers and microphones, the Konftel 55Wx
provides full duplex (two-way audio) and efficient echo cancellation and noise reduction.
The computer identifies the Konftel 55Wx as an echo cancellation device which means
that communication software usually leaves the audio processing to the Konftel 55Wx,
resulting in better sound quality. This can also be manually adjusted, for example in
Skype®.
OmniSound® performs over the full audio bandwidth (100–24000 Hz), but depending
on the equipment in the network and equipment used by the other call participants,
there may be some factors that limit the sound quality.
CONNECTION TO A COMPUTER
Connect the computer to the Konftel 55Wx using the USB cable provided.
The button is displayed on the Konftel 55Wx. The button is immediately activated on connection.
The computer's operating system normally automatically selects the Konftel 55Wx
as a speaker and microphone. If the Konftel 55Wx is not automatically selected as
an audio device in the computer, you may have to open the computer's settings and
select Konftel 55Wx.
If you have an active software program in the computer that is using the computer's
built-in speakers, it may be necessary to restart the program to switch to the new
speaker (Konftel 55Wx).

USING THE KONFTEL WITH A COMPUTER
USING THE KONFTEL WITH A COMPUTER
Using as a computer speaker
USB is immediately activated on connection ( lights up).
The computer normally only activates the speaker in the Konftel 55Wx if there is no other
program running that can use the microphone. This means that the Konftel 55Wx acts as
a computer speaker and that the audio processing in OmniSound® is turned off so that the
sound is not altered.
Using the Konftel as a conference unit
When communication software or audio recording software is started on the computer, the
Konftel 55Wx microphone is also activated. OmniSound® is now handling full duplex and
echo cancellation. The blue LEDS on the Konftel 55Wx also light up at the same time.
To make a VoIP call, use Skype®, Microsoft® Lync®, an online meeting service or some
other VoIP (Voice over IP) software.
Adjusting the volume
The volume can be adjusted on the computer and on the Konftel 55Wx.
Press the button on the Konftel 55Wx to turn the sound off quickly.
