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 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. * Electrical Delay: One—way delay between the SMA connector and the antenna feed point. No uncertainty required. * 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. Certificate No: D2450V2—728_Apr08 Page 2 of 9

Appendix Antenna Parameters with Head TSL Impedance, transformed to feed point 48.7 Q + 4.6 jQ Return Loss —26.3 dB Antenna Parameters with Body TSL Impedance, transformed to feed point 52.9 Q + 3.9 jQ Return Loss —26.5 dB General Antenna Parameters and Design Electrical Delay (one direction) 1.149 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. No excessive force must be applied to the dipole arms, because they might bend or the soldered connections near the feedpoint may be damaged.
