    4.1.          MEASURING INSTRUMENT CALIBRATION
The measuring equipment utilized to perform the tests documented in this report has been
calibrated in accordance with the manufacturer's recommendations, and is traceable to
recognized national standards.


    4.2.          MEASUREMENT UNCERTAINTY
Where relevant, the following measurement uncertainty levels have been estimated for tests
performed on the apparatus:

                                   PARAMETER                                                UNCERTAINTY

    5.2.          DESCRIPTION OF AVAILABLE ANTENNAS
The radio utilizes an internal loop antenna (Circular Coil).


    5.3.          WORST-CASE CONFIGURATION AND MODE
EUT was placed on a turntable, and the measurement probe was placed at a distance of 10 cm
from the EUT, the probe was moved from 0 to 90 degrees angle as the diagram below shows,
and the turn table was rotated 360 degrees to capture the highest signal.

The signal trace was put on max hold and the highest reading was recorded.
