INTRODUCTION  
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.

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).

LEDs  
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.

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.

USING THE KONFTEL WITH A DESKTOP PHONE  
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.

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.  
8
USING THE KONFTEL WITH A MOBILE PHONE  
The Konftel 55W transforms your mobile phone to a conference phone with OmniSound®  
HD, ensuring high sound level, full duplex (two-way audio) and efficient echo cancellation  
and noise reduction.  
OmniSound® HD performs over the full audio bandwidth (100–24000 Hz), but limita-  
tions 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 55W. The desktop phone connection is disabled when the  
mobile phone is connected.  
CABLE CONNECTION TO A MOBILE PHONE  
The Konftel 55W is connected using a cable which is adapted for your phone (optional  
accessory). The Konftel 55W 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 55W using the mobile phone cable.  
The button is displayed on the Konftel 55W. The button is immediately activated on connection.  
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 a mobile cable.  
Automatic detection of mobile phone  
The Konftel 55W 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 55W/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 31).

USING THE KONFTEL WITH A MOBILE PHONE  
MAKING CALLS  
Check that the button on the Konftel 55W 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  
55W, 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 55W  
to the phone.  
Ending calls  
End the call on the mobile phone.  
The button on the Konftel 55W can remain lit if you want to use the Konftel 55W  
for future calls too.  
10  
USING THE KONFTEL WITH A COMPUTER  
The Konftel 55W transforms your computer to teleconferencing equipment with  
OmniSound® HD. Unlike normal computer speakers and microphones, the Konftel 55W  
provides full duplex (two-way audio) and efficient echo cancellation and noise reduction.  
The computer identifies the Konftel 55W as an echo cancellation device which means that  
communication software usually leaves the audio processing to the Konftel 55W, resulting  
in better sound quality. This can also be manually adjusted, for example in Skype®.  
OmniSound® HD 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 55W using the USB cable provided.  
The  
button is displayed on the Konftel 55W. The button is immediately activated on connec-  
tion.  
The computer's operating system normally automatically selects the Konftel 55W as a  
speaker and microphone. If the Konftel 55W is not automatically selected as an audio  
device in the computer, you may have to open the computer's settings and select  
Konftel 55.  
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 55W).  
11  
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 55W if there is no other  
program running that can use the microphone. This means that the Konftel 55W acts as a  
computer speaker and that the audio processing in OmniSound® HD 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 55W microphone is also activated. OmniSound® is now handling full duplex and  
echo cancellation. The blue LEDS on the Konftel 55W 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 55W.  
Press the  
button on the Konftel 55W to turn the sound off quickly.  
12  
USING THE KONFTEL WITH BLUETOOTH  
Practically all mobile phones have Bluetooth and can be used for wireless communica-  
tion with the Konftel 55W. Bluetooth must be activated in the mobile phone's settings.  
Note that it is also possible to connect to certain desktop phones and computers with  
Bluetooth, but these may not have support for dialling numbers, for example, from the  
screen on the Konftel 55W. Also see “Connecting a phone with Headset Profile” on page 21.  
OmniSound® HD performs over the full audio bandwidth (100–24000 Hz), but limita-  
tions in the telecommunications networks and in Bluetooth technology reduce the  
bandwidth somewhat and the sound is compressed. This has an effect on the sound  
quality.  
Note that Bluetooth in the Konftel 55W can be turned off. If no button is marked on  
the display screen, open the settings and activate Bluetooth.  
PAIRING AND CONNECTING  
Two devices have to be paired before they can communicate with Bluetooth. They can be  
paired from the Konftel 55W and from your mobile phone.  
Note that a conflict may arise if you try to pair from both devices at the same time. We  
recommend searching from one device only.  
You must know the names of the devices that you want to pair in case there are lots of  
active Bluetooth devices nearby. The name of your Konftel 55W can be changed in the  
settings.  
Turn Bluetooth on in your mobile.  
This normally makes the phone visible to other Bluetooth devices and even starts a search on  
some phones.  
Press the button on the Konftel 55W to open the dialogue box with paired devices.  
This makes the Konftel 55W visible to other Bluetooth devices.

Headsets  
This setting allows you to adapt the headset port for different headsets.  
Most headsets with a 3.5 mm plug have three (mono) or four (stereo) interfaces with the  
microphone's connector furthest out on the top. If your headset does not work, it may be  
because it has another position on the interfaces.  
Headset level  
Sensitivity (audio volume) can vary from headset to headset. It is therefore possible to  
adjust the volume so that the sound heard seems to be about the same level as when  
heard via the speakers.  
Warning!  
Use of headphones/earbuds at high volumes can damage your hearing.  
A higher volume may be harmful to hearing if you have a high-sensitivity  
headset.  
Note that for safety reasons, this setting is reset when you remove your headset. This  
is because another headset that is connected may be more sensitive.  
Feature layer  
Using this setting, you can select your preferred UC solution or choose to turn the function  
off. Microsoft® Lync® is selected by default, which means that if the Konftel 55W detects  
that the Lync® client is being used by the computer, Lync® feature layer will be displayed  
on the Konftel 55W.
