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.
DESCRIPTION On / Off (long press) Mute (microphone off / speaker off) 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.
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.
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 reduction. 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.
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 55W, or transfer the sound before the call is connected.

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.
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.

For example, if you have an ongoing mobile call with a cable-connected phone and you answer an incoming call via Bluetooth, the ongoing mobile call is put on hold as illustrated below.
BRIDGE CONNECTION When bridging a computer and a phone, all you need to do is activate both sources of sound. OmniSound® HD can handle full duplex, echo cancellation and noise reduction for both the sound sources simultaneously.
