Using a headset

To make hands-free calls with your FRITZ!Fon, you can either use the "hands-free" calling function or you can use a headset. The telephone has a socket for 3.5 mm jack plugs on its top side.

Standard headsets for mobile telephones with an earphone impedance of 32 Ohms and a microphone impedance in the range of 800-2200 ohms (+/- tolerance) are suitable. You can use stereo or mono headsets with the assignment shown below. The mechanical protection of the plug should not exceed 7 mm to ensure good contact.
