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
OmniSound® HD performs over the full audio bandwidth
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.
