In the case of location with other devices at a fixed site installation, Users and installers must be provided with appropriate antenna installation instructions and transmitter operating conditions, including antenna co-location requirements of §1.1307(b)(3), for satisfying RF exposure compliance. FCC s MPE Requirements Information to user/installer regarding FCC s Maximum Permissible Exposure (MPE) limits. FCC rules limit the use of this antenna, when connected to Cirronet RF products for point-to-point applications only. It is the responsibility of the installer to ensure that the system is prohibited from being used in point-to-multipoint applications, omni-directional applications, and applications where there are multiple co-located intentional radiators transmitting the same information . Any other mode of operation using this antenna is forbidden. Notice to users/installers using the following mobile antennas, with Cirronet RF products: MaxRad 8 dBi omni-directional, The field strength radiated by any one of these antennas, when connected to Cirronet RF products, may exceed FCC mandated RF exposure limits. FCC rules require professional installation of these antennas in such a way that the general public will not be closer than 20 cm from the radiating aperture of any of these antennas. End users of these systems must also be informed that RF exposure limits may be exceeded if personnel come closer than 20 cm to the apertures of any of these antennas. Note: This unit has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at their expense. Declaration of Conformity Warning! The RLAN transceiver within this device uses a band of frequencies that are not completely harmonized within the European Community. Before using, please read the European Operation Section of the Products User’s Guide for limitations. The WIT2410T to which this declaration relates is in conformity with the essential requirements of the R&TTE directive 1999/5/EC and complies with the following standards and/or other normative documents: EN 300 328 Use Within the European Union The WIT2410T is intended for use within the European Community States and in the following non-European Union States: Norway & Switzerland Use of the WIT2410T in France When used in France, the WIT2410T can only be operated with the France hopping pattern selected. This is accomplished by setting the pe parameter to 1. Refer to European Union Settings in this manual for details. Canadian Department of Communications Industry Canada (IC) Notice Canadian Department of Communications Industry Canada (IC) Notice This apparatus complies with Health Canada’s Safety Code 6 / IC RSS 102. "To prevent radio interference to the licensed service, this device is intended to be operated indoors and away from windows to provide maximum shielding. Equipment (or its transmit antenna) that is installed outdoors may be subject to licensing." ICES-003 This digital apparatus does not exceed the Class B limits for radio noise emissions from digital apparatus as set out in the radio interference regulations of Industry Canada. Le présent appareil numérique n'émet pas de bruits radioélectriques dépassant les limites applicables aux appareils numériques de Classe B prescrites dans le règlement sur le brouillage radioélectrique édicté par Industrie Canada.
