Registering FRITZ!DECT Repeater

You can use a FRITZ!DECT Repeater to increase the DECT range of your DECT base station (for example a FRITZ!Box) so you can then even make calls with your cordless telephones from your garden or on different floors of your house. If you leave the coverage area of one device while making a call, the telephone will automatically connect to the other device without interrupting the call.

Here we show you how to register the FRITZ!DECT repeater with a FRITZ!Box at the touch of a button. Instead of a FRITZ!Box, you can also use a DECT base station from another manufacturer.

Requirements / Restrictions

  • A maximum of six repeaters (FRITZ!DECT Repeaters and/or FRITZ!Boxes in DECT repeater mode) can be registered with the FRITZ!Box.
  • DECT repeaters from other manufacturers and FRITZ!DECT Repeaters cannot be registered at the same time.
  • All repeaters must be registered with the base station (star topology). It is not possible to register a repeater with another repeater (cascading).
  • The "DECT Eco" function can no longer be used.

1 Establishing a DECT connection

  1. Plug the repeater into a power outlet near the FRITZ!Box.
  2. Push the "DECT" button on the repeater. Hold down the button for at least 6 seconds until the "DECT" LED starts to flash rapidly. The repeater is in registration mode as long as the LED flashes rapidly.
  3. Within 2 minutes: Push the registration button on the FRITZ!Box. Which button you must push depends on the FRITZ!Box model:

    Note:With FRITZ!Box models that have both "DECT" and "Connect" buttons, you can use either button.

    • If your model has a "Connect" button, push the "Connect" button on the FRITZ!Box. Hold down the button for about 1 second until the "Connect" LED starts to flash. The FRITZ!Box is in registration mode as long as the LED flashes. Other LEDs may flash as well.
    • If your model has a "DECT" button, push the "DECT" button on the FRITZ!Box. Hold down the button for at least 6 seconds until the "DECT" or "Info" LED on the FRITZ!Box starts to flash. The FRITZ!Box is in registration mode as long as the LED flashes.
  4. The "DECT" LED on the repeater remains lit as soon as the DECT connection has been established.

2 Finding the ideal location for the repeater

  1. Select a location for the repeater where a telephone that is registered directly with the FRITZ!Box still has perfect reception. The "DECT" LED on the repeater must remain lit. If the LED flashes, the repeater has no connection to the FRITZ!Box. In addition, at the location you select for the repeater, voice transmission with every telephone must be absolutely interference-free in both directions when the repeater is switched off. Otherwise, the location is not a suitable place to position the repeater.

Now the repeater extends the DECT range of the base station. Register new telephones with the base station. You cannot register telephones with the repeater.

Note:FRITZ!Fons now display a small red 1 over the signal strength bars when they are logged onto the base station and a 2 when they are logged onto the repeater. If you are using several repeaters, the numbers 2 to 7 are used.
