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.

 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 internal antenna which permanently attached, and the best case
 gain of the ante nna is 2.20Bi.

                                     coupling impedance with 50ohm termination. (Please

                                4. For each suspected emission, the EUT was arranged
                                    to its worst case and then the antenna was tuned to
                                    heights from 1 meter to 4 meters and the rotatable
                                    table was turned from 0 degrees to 360 degrees to
                                    find the maximum reading.
                                5. The test-receiver system was set to Peak Detect

                                   10dB lower than the limit specified, then testing could
                                   be stopped and the peak values of the EUT would be
                                   reported. Otherwise the emissions that did not have
                                   10dB margin would be re-tested one by one using
                                   peak, quasi-peak or average method as specified and
                                   then reported in a data sheet.
