The ColumbaTD integrates a hand free telephone, because of the purpose of the ColumbaTD; the wearer cannot dial a number or
make a call himself. The ColumbaTD can only receive calls originating from the medical assistance central or tutors.
At the time of the reception of a call, the wearer will automatically be in communication with the caller (the wearer does not have any
action to perform to accept the call). This product has a speaker-phone mode and since the speaker is always at its maximum power
and the microphone is extremely sensitive it not required or intended to be held directly in front of the face.

available.
