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 every 48 hours or within 30 minutes of being restarted. If the FRITZ!Box finds new firmware, it is updated automatically. You can see which version is installed if you select the menu "DECT > DECT Monitor" in the FRITZ!Box user interface. Power to the connected devices is not interrupted during an update.
