t o n n ~> > — Appendix (Additional assessments outside the scope of SCS 01 08) Antenna Parameters with Head TSL Impedance, transformed to feed point 474 Q —7.4 jQ Return Loss —21.9 dB Antenna Parameters with Body TSL Impedance, transformed to feed point 44.1 Q — 4.9 jQ Return Loss —21.8 dB General Antenna Parameters and Design Electrical Delay (one direction) 1.154 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.

No.I19Z60072-SEM01 Page 154 of 156 According to the above description, this device was tested by the manufacturer to determine the SAR sensor triggering distances for the rear and bottom edge of the device. The measured power state within ±5mm of the triggering points (or until touching the phantom) is included for rear and each applicable edge. To ensure all production units are compliant it is necessary to test SAR at a distance 1mm less than the smallest distance from the device and SAR phantom with the device at maximum output power without power reduction. We tested the power and got the different proximity sensor triggering distances for rear and bottom edge. But the manufacturer has declared 23mm is the most conservative triggering distance for main antenna. So base on the most conservative triggering distance of 23mm, additional SAR measurements were required at 22mm from the highest SAR position between rear and bottom edge of main antenna.

No.I19Z60072-SEM01 Page 155 of 156 The influence of table tilt angles to proximity sensor triggering is determined by positioning each edge that contains a transmitting antenna, perpendicular to the flat phantom, at the smallest sensor triggering test distance by rotating the device around the edge next to the phantom in ≤ 10° increments until the tablet is ±45°or more from the vertical position at 0°. The rear evaluation for main antenna The bottom edge evaluation for main antenna Based on the above evaluation, we come to the conclusion that the sensor triggering is not released and normal maximum output power is not restored within the ±45°range at the smallest sensor triggering test distance declared by manufacturer. ©Copyright.
