Cannot register a FRITZ!DECT socket

Registration of the outlet switch, for example FRITZ!DECT 200, fails. After the automatic configuration, the "DECT" LED flashes continuously and the DECT connection between FRITZ!Box and FRITZ!DECT is not established.

Simply proceed as described below. After each measure, check whether the problem persists.

1 Maximum number has been reached

You can register a maximum of ten FRITZ!DECT devices (for example FRITZ!DECT 200) with the FRITZ!Box. If you already registered ten devices, you cannot register any more devices.

Note:Registering a FRITZ!DECT does not reduce the number of telephones, DECT repeaters, or radiator controls that you can register.
