4.1. Test Environment and Mode
  Operating Environment:
     Temperature:                               25.0 C
     Humidity:                                  54 % RH
     Atmospheric Pressure:                      1010 mbar

  Test Mode:
                                                Keep the EUT in continuous transmitting by select
     Engineering mode:
                                                channel
  The sample was placed (0.8m below 1GHz, 1.5m above 1GHz) above the ground
  plane of 3m chamber. Measurements in both horizontal and vertical polarities were
  performed. During the test, each emission was maximized by: having the EUT
  continuously working, investigated all operating modes, rotated about all 3 axis (X, Y &
  Z) and considered typical configuration to obtain worst position, manipulating
  interconnecting cables, rotating the turntable, varying antenna height from 1m to 4m in
  both horizontal and vertical polarizations. The emissions worst-case are shown in Test
  Results of the following pages.


4.2. Description of Support Units
 The EUT has been tested as an independent unit together with other necessary
 accessories or support units. The following support units or accessories were used to
 form a representative test configuration during the tests.


  Equipment              Model No.               Serial No.               FCC ID               Trade Name

 Note:
     1. All the equipment/cables were placed in the worst-case configuration to maximize the emission during the test.
     2. Grounding was established in accordance with the manufacturer’s requirements and conditions for the intended
         use.

6.1. Antenna Requirement

 Standard requirement:            FCC Part15 C Section 15.203
 15.203 requirement:
 An intentional radiator shall be designed to ensure that no antenna other than that
 furnished by the responsible party shall be used with the device. The use of a
 permanently attached antenna or of an antenna that uses a unique coupling to the
 intentional radiator, the manufacturer may design the unit so that a broken antenna
 can be replaced by the user, but the use of a standard antenna jack or electrical
 connector is prohibited.
 E.U.T Antenna:
 The EUT antenna is PCB antenna which permanently attached, and the best case gain
 of the antenna is -2dBi.

                                    (L.L.S.N.). This provides a 50ohm/50uH coupling

                                    to its worst case and then the antenna was tuned to

                                    table was turned from 0 degrees to 360 degrees to

                                   be stopped and the peak values of the EUT would be

 2. Margin (dB) = Emission Level (Peak) (dBµV/m)-Average limit (dBµV/m)
 3. The emission levels of other frequencies are very lower than the limit and not show in test report.
 4. Measurements were conducted from 1 GHz to the 10th harmonic of highest fundamental frequency.
 5. Data of measurement shown “---“in the above table mean that the reading of emissions is attenuated more than 20
  dB below the limits or the field strength is too small to be measured.
