Cannot register a FRITZ!DECT radiator control

Registration of the radiator control, for example FRITZ!DECT 301, to the FRITZ!Box fails. After you push the DECT or Connect button on the FRITZ!Box, the DECT connection is not established. The symbol for the radio connection is not permanently shown in the display of the radiator control. The radiator control is not displayed or is displayed with an inactive connection in the menu "(Home Network >) Smart Home" in the FRITZ!Box.

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.

You can register up to twelve radiator controls with the FRITZ!Box. If you have already registered twelve devices, you cannot register any more.
