All figures stated in the certificate are valid at the frequency indicated. * Antenna Parameters with TSL: The dipole is mounted with the spacer to position its feed point exactly below the center marking of the flat phantom section, with the arms oriented parallel to the body axis. * Feed Point Impedance and Return Loss: These parameters are measured with the dipole positioned under the liquid filled phantom. The impedance stated is transformed from the measurement at the SMA connector to the feed point. The Return Loss ensures low reflected power. No uncertainty required. * Electrical Delay: One—way delay between the SMA connector and the antenna feed point. No uncertainty required. e SAR measured: SAR measured at the stated antenna input power. * SAR normalized: SAR as measured, normalized to an input power of 1 W at the antenna connector. «_ SAR for nominal TSL parameters: The measured TSL parameters are used to calculate the nominal SAR result. The reported uncertainty of measurement is stated as the standard uncertainty of measurement multiplied by the coverage factor k=2, which for a normal distribution corresponds to a coverage probability of approximately 95%.

Appendix (Additional assessments outside the scope of SCS108) Antenna Parameters with Head TSL Impedance, transformed to feed point 50.9 Q — 3.6 jQ Return Loss —28.6 dB Antenna Parameters with Body TSL Impedance, transformed to feed point 46.9 Q — 5.6 jQ Return Loss —23.6 dB General Antenna Parameters and Design Electrical Delay (one direction) 1.397 ns After long term use with 100W radiated power, only a slight warming of the dipole near the feedpoint can be measured. The dipole is made of standard semirigid coaxial cable. The center conductor of the feeding line is directly connected to the second arm of the dipole. The antenna is therefore short—circuited for DC—signals. On some of the dipoles, small end caps are added to the dipole arms in order to improve matching when loaded according to the position as explained in the "Measurement Conditions" paragraph. The SAR data are not affected by this change. The overall dipole length is still according to the Standard. No excessive force must be applied to the dipole arms, because they might bend or the soldered connections near the feedpoint may be damaged.

Calibration Laboratory of Schweizerischer Kalibrierdienst Schmid & Partner Service suisse d‘étalonnage Engineering AG Servizio svizzero di taratura Zeughausstrasse 43, 8004 Zurich, Switzerland Swiss Calibration Service Accredited by the Swiss Accreditation Service (SAS) Accreditation No.: SCS 108 The Swiss Accreditation Service is one of the signatories to the EA Multilateral Agreementfor the recognition of calibration certificates Glossary: TSL tissue simulating liquid ConvF sensitivity in TSL / NORM x,y,z N/A not applicable or not measured Calibration is Performed According to the Following Standards: a) IEEE Std 1528—2013, "IEEE Recommended Practice for Determining the Peak Spatial— Averaged Specific Absorption Rate (SAR) in the Human Head from Wireless Communications Devices: Measurement Techniques", June 2013 b) IEC 62209—1, "Procedure to measure the Specific Absorption Rate (SAR) for hand—held devices used in close proximity to the ear (frequency range of 300 MHz to 3 GHz)", February 2005 c) KDB 865664, "SAR Measurement Requirements for 100 MHz to 6 GHz" Additional Documentation: d) DASY4/5 System Handbook Methods Applied and Interpretation of Parameters: * Measurement Conditions: Further details are available from the Validation Report at the end of the certificate. All figures stated in the certificate are valid at the frequency indicated. e Antenna Parameters with TSL: The dipole is mounted with the spacer to position its feed point exactly below the center marking of the flat phantom section, with the arms oriented paralle! to the body axis. * Feed Point Impedance and Return Loss: These parameters are measured with the dipole positioned under the liquid filled phantom. The impedance stated is transformed from the measurement at the SMA connector to the feed point. The Return Loss ensures low reflected power. No uncertainty required. e Electrical Delay: One—way delay between the SMA connector and the antenna feed point. No uncertainty required. e SAR measured: SAR measured at the stated antenna input power. e SAR normalized: SAR as measured, normalized to an input power of 1 W at the antenna connector. «_ SAR for nominal TSL parameters: The measured TSL parameters are used to calculate the nominal SAR result. The reported uncertainty of measurement is stated as the standard uncertainty of measurement multiplied by the coverage factor k=2, which for a normal distribution corresponds to a coverage probability of approximately 95%.

Appendix (Additional assessments outside the scope of SCS108) Antenna Parameters with Head TSL Impedance, transformed to feed point 54.4 Q + 3.1 jQ Return Loss —25.7 dB Antenna Parameters with Body TSL Impedance, transformed to feed point 50.4 Q + 4.4 jQ Return Loss —27.1 dB General Antenna Parameters and Design Electrical Delay (one direction) 1.147 ns After long term use with 100W radiated power, only a slight warming of the dipole near the feedpoint can be measured. The dipole is made of standard semirigid coaxial cable. The center conductor of the feeding line is directly connected to the second arm of the dipole. The antenna is therefore short—circuited for DC—signals. On some of the dipoles, small end caps are added to the dipole arms in order to improve matching when loaded according to the position as explained in the "Measurement Conditions" paragraph. The SAR data are not affected by this change. The overall dipole length is still according to the Standard. No excessive force must be applied to the dipole arms, because they might bend or the soldered connections near the feedpoint may be damaged.
