Since damage caused by power surges (e.g., after lightning strikes) is not covered by the manufacturer's warranty, FRITZ! does not offer replacements. It is also not possible to repair devices damaged by power surges because the damaged microelectronic components cannot be replaced. Furthermore, power surge damage is generally not covered by the warranty because the damage originates outside of the FRITZ! device itself.

However, many contents insurance policies cover the cost of replacing electronic devices in the event of power surge damage. Insurers can often refer you to loss adjusters to inspect your device and certify that it was damaged by a power surge. FRITZ! does not issue such insurance certificates. If you have contents insurance, refer to your insurance company for further information.

The German Federal Office for Information Security notes on its website that the sources of surge damage are not limited to power lines. Connected devices can also be damaged via the phone network and internet connections (for example via the DSL connection). To prevent damage, always disconnect your devices from the internet, phone network, and the power source whenever there is a thunderstorm. Do not reconnect them until the thunderstorm is over.

Apart from that, only a multi-level protection system according to the corresponding standard on lightning protection can offer reliable protection. Since these measures have to be adapted to the actual conditions at your location (concept of energy coordination), we cannot give you any specific recommendations on implementing them. You can find detailed information on this topic if you search for 'surge protection' on the internet, for example on Wikipedia.
