FCC Statement  This equipment 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 in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:  —Reorient or relocate the receiving antenna.  —Increase the separation between the equipment and receiver.  —Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.  —Consult the dealer or an experienced radio/TV technician for help. — Any Changes or modifications not expressly approved by the party responsible for compliance could void theuser’s authority to operate the equipment. FCC Radiation Exposure Statement  This device complies with FCC SAR exposure limits set forth for an uncontrolled environment. The SAR limit of USA (FCC) is 1.6 W/kg averaged over one gram of tissue. SAR compliance for using the equipment in close proximity to the human body has been evaluated at 0mm.This equipment must not be co-located or operating in conjunction with any other antenna or transmitter. End-users and installers must be provide with antenna installation instructions and consider removing the no-collocationstatement.  This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation.

Figure 1 – MVG COMOSAR Dosimetric E field Dipole Probe Length 330 mm Length of Individual Dipoles 2 mm Maximum external diameter 8 mm Probe Tip External Diameter 2.5 mm Distance between dipoles / probe extremity 1 mm 3 MEASUREMENT METHOD The IEEE 1528, FCC KDB865664 D01, CENELEC EN62209 and CEI/IEC 62209 standards provide recommended practices for the probe calibrations, including the performance characteristics of interest and methods by which to assess their affect. All calibrations / measurements performed meet the fore mentioned standards. 3.1 LINEARITY The evaluation of the linearity was done in free space using the waveguide, performing a power sweep to cover the SAR range 0.01W/kg to 100W/kg.

The information contained herein is to be used only for the purpose for which it is submitted and is not to be released in whole or part without written approval of MVG. 3.2 SENSITIVITY The sensitivity factors of the three dipoles were determined using a two step calibration method (air and tissue simulating liquid) using waveguides as outlined in the standards. 3.3 LOWER DETECTION LIMIT The lower detection limit was assessed using the same measurement set up as used for the linearity measurement. The required lower detection limit is 10 mW/kg. 3.4 ISOTROPY The axial isotropy was evaluated by exposing the probe to a reference wave from a standard dipole with the dipole mounted under the flat phantom in the test configuration suggested for system validations and checks. The probe was rotated along its main axis from 0 to 360 degrees in 15- degree steps. The hemispherical isotropy is determined by inserting the probe in a thin plastic box filled with tissue-equivalent liquid, with the plastic box illuminated with the fields from a half wave dipole. The dipole is rotated about its axis (0°–180°) in 15° increments. At each step the probe is rotated about its axis (0°–360°). 3.5 BOUNDARY EFFECT The boundary effect is defined as the deviation between the SAR measured data and the expected exponential decay in the liquid when the probe is oriented normal to the interface. To evaluate this effect, the liquid …
