Cannot register FRITZ!DECT

The registration of FRITZ!DECT (for example FRITZ!DECT 200) fails. After automatic configuration, the "DECT" LED flashes continuously and a DECT connection between FRITZ!Box and FRITZ!DECT cannot be established.

Note:The configuration procedure and notes on functions given in this guide refer to the latest FRITZ!OS for your FRITZ!Box.

Simply proceed as described below. After each measure, check whether the issue 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, then you cannot register any additional devices.
