17 Regulatory Compliance Information 2. Regulatory Compliance Information The use of radio frequencies is limited by national regulations. The radio module has been designed to comply with the European Union s R&TTE (Radio & Telecommunications Terminal Equipment) directive 1999/5/EC and can be used free of charge within the European Union. Nevertheless, restrictions in terms of maximum allowed RF power or duty cycle may apply. The radio module has been designed to be embedded into other products (referred as final products ). According to the R&TTE directive, the declaration of compliance with essential requirements of the R&TTE directive is within the responsibility of the manufacturer of the final product. A declaration of conformity for the radio module is available from IMST GmbH on request. The applicable regulation requirements are subject to change. IMST GmbH does not take any responsibility for the correctness and accuracy of the aforementioned information. National laws and regulations, as well as their interpretation can vary with the country. In case of uncertainty, it is recommended to contact either IMST s accredited Test Center or to consult the local authorities of the relevant countries.
