Konftel 50 is a conference unit for connecting to existing fixed system telephones, DECT telephones, mobile phones or computers. Konftel 50 has a omnidirectional, highly-sensitive microphone and three speakers which, together with Konftels OmniSound provide optimal sound quality and maximum reduction of room echo, even when the person speaking is standing at a slight distance from the unit. Konftel 50 has five buttons. The most common functions for power, speaker volume and mute are obvious, but all the buttons have other functions for activating various special functions and settings. Therefore, you should read the sections of the handbook that deal with the connections you intend to use so that you do not miss any important options.

Do not place the unit too close to a wall or underneath objects such as lampshades or pot plants. 2. Tune Konftel 50 manually. See instructions for manual tuning. 3. Is the volume correctly adjusted? See the instructions for adjusting the volume setting for the microphone. 4. Is the other party using a conference unit, sound card or software that cannot handle full duplex? 5.
