FRITZ!DECT Repeater 100 Service

Loud background noise when using a FRITZ!DECT Repeater

You hear loud background noise when conducting calls with a cordless telephone as soon as a FRITZ!DECT Repeater is registered with the FRITZ!Box.

Cause

  • The repeater is not correctly connected with the FRITZ!Box or it was not positioned correctly.

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.

1 Preparations

DECT technology is constantly evolving. To ensure that the FRITZ!Box is up-to-date, install the latest FRITZ!OS:

  1. Install the latest FRITZ!OS on the FRITZ!Box.

2 Configuring the FRITZ!Box

Enabling encryption

  1. Open the FRITZ!Box user interface.
  2. Click "Base Station" in the "DECT" menu or "DECT" in the "Telephony" menu.
  3. Enable the option "Permit only secure DECT connections (recommended)" in the section "Security".
  4. Click "Apply" to save the settings.
  5. If the option was disabled, you must then restart the FRITZ!Box once using the user interface ("System > Backup > Restart").

Setting a PIN

  1. Open the FRITZ!Box user interface.
  2. Click "Base Station" in the "DECT" menu or "DECT" in the "Telephony" menu.
  3. Enter "0000" as the PIN in the section "Registration".
  4. Click "Apply" to save the settings.

Important:The PIN may not be changed even after you have successfully registered the repeater!

3 Re-registering a repeater

Deregistering a repeater

  1. Push and hold down the "DECT" button on the repeater twice in a row for at least 6 seconds each time.

The "DECT" LED flashes as soon as the repeater is deregistered.

Restarting the FRITZ!Box

  1. Click "System" in the FRITZ!Box user interface.
  2. Click "Backup" in the "System" menu.
  3. Click on the "Restart" tab.
  4. Click the "Restart" button.

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 "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.

4 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.
