ANNEX I          Sensor Triggering Data Summary




                                                 .

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 front, rear and
bottom edge. But the manufacturer has declared 2mm is the most conservative triggering distance
for main antenna. So base on the most conservative triggering distance of 2mm, additional SAR
measurements were required at 1mm from the highest SAR position.

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 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.
