Additional Feedback on FRITZ!OS

In addition to direct feedback in our lab area en.avm.de/fritz-lab, there are three additional feedback functions in the user interface which provide information. We have automated the processing of feedback supplied by these functions.

1) DSL feedback via "Internet / DSL Information / Feedback" 2) Wi-Fi feedback via "Wi-Fi / Wi-Fi Network": Feedback icon after the clients 3) VoIP feedback via "Telephony / Telephone Numbers / Voice Transmission", "Other" column: Feedback icon after each call

Information on the Lab update:

This FRITZ! Lab firmware is a beta version. We've tested it in standard environments before release, but it may still result in bugs. AVM is not liable for any damages that may arise from the use of the Lab version.

Information on working with Lab versions

We appreciate any feedback from our users, which can be submitted at: en.avm.de/fritz-lab. This page also lists all of the current FRITZ! Lab versions with corresponding feedback areas.

Before you start testing the Lab version

1) You haven't installed the latest firmware for your FRITZ!Box yet? You first need to update the firmware to the latest release. 2) Save your current settings under "System / Backup". The saved settings will be needed if you want to switch back from the Lab firmware back to the release firmware.

Testing the Lab version

Once the latest FRITZ!OS version has been installed on your FRITZ!Box and you've saved your current settings, you can begin testing.

1) Unzip the "fritzbox-yyyy-labor-xxxxx.zip" file. 2) Use the FRITZ!Box user interface to install the update:

• Select "View: Advanced" in the footer.
• Click "Update" in the "System" menu.
• Switch to the "FRITZ!OS File" tab.
• Follow the instructions displayed on the screen.
• Enter the path to the Lab firmware and the name of the Lab file (FRITZ.Box_xxxx-0x.xx-xxxxx-Labor.image) in the input field. 3) The Lab version is installed on the FRITZ!Box. The FRITZ!Box will then restart.

Restoring your device to how it was before testing You can switch back to the official FRITZ!OS at any time under "System > Update > FRITZ!OS Version" or reset the FRITZ!Box back to the official FRITZ!OS using the enclosed Windows program "recover.exe" (included in the Lab package).
