Power supply / fuse protection
The Wi2U router comes with an integrated overvoltage protection and reverse voltage
protection. Additionally, the device is protected against short circuit by a 2A fuse.

Important Notes
Notes for end user: Any change or modification to the Wi2U router, which was not
explicitly released by an authorised certification body as conforming to regulatory re-
quirements, may terminate the operating license of the device.
Safety guidelines: Do not operate the Wi2U router in any area where medical equip-
ment, life-saving devices or other devices are used which are sensitive to interference
from radio signals.
Operation in the vehicle: The driver or person operating the vehicle should not ope-
rate the Wi2U router while driving. The operation of the Wi2U router diverts the attenti-
on of the driver from traffic ahead and control of the vehicle. In some countries, the use
of such communication devices while operating a motor vehicle is prohibited. Please
observe the country-specific conditions.
Please note: The UMTS antenna should not be operated near another antenna.
The UMTS antenna should have a minimum distance of 2 cm from metal and 20 cm
distance from the human body. The correct antenna position in the vehicle has a
significant influence on connection quality. The existence of an Internet connection is
dependent on the use of a mobile tariff with integrated data option.
The transmission speed depends on the infrastructure of the network operator, the
current signal strength and the number of users in a radio cell. The Wi2U router does
not have a SIM lock and can therefore be used with any SIM card with a data tariff.
