4. General Information
4.1. Test environment and mode
  Operating Environment:
     Temperature:                                              25.0 C
     Humidity:                                                 56 % RH
     Atmospheric Pressure:                                     1010 mbar

  Test Mode:
     Engineering mode:                                         Keep the EUT in continuous transmitting
                                                               by select channel and modulations with
                                                               Fully-charged battery
  The sample was placed 0.8m & 1.5m for the measurement below & 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

    Adapter          XC-0501000-06-B                       /                    /                ADAPTER
 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.

     3. For conducted measurements (Output Power, 20dB Occupied Bandwidth, Carrier Frequencies Separation,
         Hopping Channel Number, Dwell Time, Spurious Emissions), the antenna of EUT is connected to the test
         equipment via temporary antenna connector, the antenna connector is soldered on the antenna port of EUT, and
         the temporary antenna connector is listed in the Test Instruments.

6.1. Antenna requirement

     Standard requirement:           FCC Part15 C Section 15.203 /247(c)
     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.
     15.247(c) (1)(i) requirement:
     (i) Systems operating in the 2400-2483.5 MHz band that is used exclusively for fixed.
     Point-to-point operations may employ transmitting antennas with directional gain
     greater than 6dBi provided the maximum conducted output power of the intentional
     radiator is reduced by 1 dB for every 3 dB that the directional gain of the antenna
     exceeds 6dBi.
     E.U.T Antenna:
     The Bluetooth antenna is PCB antenna which permanently attached, and the best
     case gain of the antenna is 0dBi.

                                    impedance stabilization network (L.I.S.N.). This
                                    provides a 50ohm/50uH coupling impedance for the
                                    measuring equipment.

                                           4. Enable the EUT hopping function.
 Test Procedure:                           5. Use the following spectrum analyzer settings:
                                               Span = wide enough to capture the peaks of two adjacent
