Cannot enable DECT Eco function

For technical reasons, the "DECT Eco" function is not available if a smart home device (for example FRITZ!DECT 200), a FRITZ!DECT Repeater 100, or a FRITZ!Box in DECT repeater mode is registered with the FRITZ!Box.

Note:If you are no longer using the above-mentioned devices, you can delete them in the menu "Smart Home" or "Telephony > DECT > Monitor" in the FRITZ!Box user interface.
