FRITZ!DECT Repeater 100 Service - Knowledge Base
Updating the firmware
During operation, the FRITZ!Box checks for updates for all of the registered DECT devices at regular intervals (approximately every 48 hours) or within 30 minutes of being restarted. If the FRITZ!Box finds new firmware for FRITZ!DECT, it is updated automatically. Power to the connected devices is not interrupted during the update procedure. You can see which version is installed if you select the menu "DECT > DECT Monitor" in the FRITZ!Box user interface.
