Important information for handsfree calling
The person who is speaking cannot hear the other party
Do not install the telephone in bare, echo-
ing rooms.
Make sure that the handsfree microphone
on the underside of the telephone is not
obstructed. For example, do not place your
telephone on a soft surface into which it
could sink.
Handsfree calls can be impaired if
– the background noises in the room are
too loud,
– the transmission paths are highly atte-
nuated (this can for example arise with
analog external links),
– with long-distance connections a strong
line echo is produced.
In this event lift the handset and thus conti-
nue your call without disturbance.
Speak in turns and let the other party finish
before starting to talk. Otherwise you may
miss parts of the conversation. Your tele-
phone always connects the direction pro-
ducing the strongest acoustic signals. The
other direction is attenuated.
