DESCRIPTION

Konftel 50 is a conference unit for connecting to existing ﬁxed system telephones,

DECT telephones, cell 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 vol-

ume 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.
