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 Konftel’s
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.

USING A SYSTEM TELEPHONE
Using a headset instead of the handset
You can connect a headset to the switchbox instead
of a handset. Please note that the headset must be
suitable for the telephone system.
Adjusting the microphone sensitivity
The microphone volume can be adjusted during the
call, but to avoid disturbing the call, it may be best to
adjust it during a test call following connection. There
are 5 volume settings.
Press and hold the mute button for about 3
3 sec
or
seconds until the LEDs start to flash and you hear
a tone.
Increase the microphone volume using the + and
reduce it using –.
Adjust the microphone volume one level at a time
until you can hear well in the other end. Please note
that too high a level may cause echoes and feedback.
Press the mute button to conclude setting the
selected microphone volume.
The volume setting is saved in the event of a powerfailure.
