 Methods Applied and Interpretation of Parameters:
    e 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.
      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.
    e 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%.

Antenna Parameters with Body TSL

      Impedance, transformed to feed point                                           43.8 Q — 4.7 jQ
      Return Loss                                                                       —21.6 dB




General Antenna Parameters and Design

      Electrical Delay (one direction)                                                   1.153 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.

According to the above description, this device was tested by the manufacturer to determine the
SAR sensor triggering distances for the rear, left edge and top 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, left edge
and top edge. But the manufacturer has declared 16mm (rear/bottom) / 11mm (front) are the most

     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 bottom edge evaluation



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.
