[2] ANSI—C63.19—2007 American National Standard for Methods of Measurement of Compatibility between Wireless Communications Devices and Hearing Aids. Methods Applied and Interpretation of Parameters: Coordinate System: y—axis is in the direction of the dipole arms. z—axis is from the basis of the antenna (mounted on the table) towards its feed point between the two dipole arms. x—axis is normal to the other axes. In coincidence with the standards [1, 2], the measurement planes (probe sensor center) are selected to be at a distance of 10 mm above the top edge of the dipole arms. Measurement Conditions: Further details are available from the hardcopies at the end of the certificate. All figures stated in the certificate are valid at the frequency indicated. The forward power to the dipole connector is set with a calibrated power meter connected and monitored with an auxiliary power meter connected to a directional coupler. While the dipole under test is connected, the forward power is adjusted to the same level. Antenna Positioning: The dipole is mounted on a HAC Test Arch phantom using the matching dipole positioner with the arms horizontal and the feeding cable coming from the floor. The measurements are performed in a shielded room with absorbers around the setup to reduce the reflections. It is verified before the mounting of the dipole under the Test Arch phantom, that its arms are perfectly in a line. It is installed on the HAC dipole positioner with its arms parallel below the dielectric reference wire and able to move elastically in vertical direction without changing its relative position to the top center of the Test Arch phantom. The vertical distance to the probe is adjusted after dipole mounting with a DASY4 Surface Check job. Before the measurement, the distance between phantom surface and probe tip is verified. The proper measurement distance is selected by choosing the matching section of the HAC Test Arch phantom with the proper device reference point (upper surface of the dipole) and the matching grid reference point (tip of the probe) considering the probe sensor offset. The vertical distance to the probe is essential for the accuracy. Feed Point Impedance and Return Loss: These parameters are measured using a HP 8753E Vector Network Analyzer. The impedance is specified at the SMA connector of the dipole. The influence of reflections was eliminating by applying the averaging function while moving the dipole in the air, at least 70cm away from any obstacles. E— field distribution: E field is measured in the x—y—plane with an isotropic ER3D—field probe with 100 mW forward power to the antenna feed point. In accordance with [1, 2], the scan area is 20mm wide, its length exceeds the dipole arm length (180 or $Omm). The sensor center is 10 mm (in z) above the top of the dipole arms. Two 3D maxima are available near the end of the dipole arms. Assuming the dipole arms are perfectly in one line, the average of these two maxima (in subgrid 2 and subgrid 8) is determined to compensate for any non—parallelity to the measurement plane as well as the sensor displacement. The E—field value stated as calibration value represents the maximum of the interpolated 3D—E—field, 10mm above the dipole surface. H—field distribution: H—field is measured with an isotropic H—field probe with 100mW forward power to the antenna feed point, in the x—y—plane. The scan area and sensor distance is equivalent to the E—field scan. The maximum of the field is available at the center (subgrid 5) above the feed point. The H—field value stated as calibration value represents the maximum of the interpolated H—field, 10mm above the dipole surface at the feed point. Certificate No: CD2450V3—1026_Apr09 Page 2 of 6

The dipole is built of standard semirigid coaxial cable. The internal matching line is open ended. The antenna is therefore open for DC signals. Do not apply force to dipole arms, as they are liable to bend. The soldered connections near the feedpoint may be damaged. After excessive mechanical stress or overheating, check the impedance characteristics to ensure that the internal matching network is not affected. After long term use with 40W radiated power, only a slight warming of the dipole near the feedpoint can be measured. Certificate No: CD2450V3—1026_Apr09 Page 3 of 6
