It is normal for the FRITZ!Box to heat up depending on the operating load. Therefore, choose a location for the FRITZ!Box where it is not subject to additional heat and good heat dissipation is assured:

1. Make sure that the ventilation slits are unobstructed. Do not place the FRITZ!Box on a carpet or on upholstered furniture.
2. Do not expose the FRITZ!Box or the power adapter to direct sunlight.
3. Do not place the FRITZ!Box inside a closed cabinet or casing.
4. Do not position the FRITZ!Box directly next to devices that also produce heat.
5. Do not place the FRITZ!Box on heat-sensitive surfaces.
