Using a headset

Not only can you use the "hands-free calling" function to make hands-free calls with your FRITZ!Fon, you can also use a headset with it. The telephone has a socket for 3.5 mm jack plugs on its top side.

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