1.2 Additional information about the EUT

The EUT is a Remote control for ceiling fan, and was defined as information
technology equipment.

Modification (R1) to test report No.: TW14040007(R1) (Verification No.:
TW14040007(R1))
The original Test Report Ref. No.: TW14040007, dated Apr. 25, 2014 was modified on
Aug. 21, 2014 to include the following changes and/or additions, which were
considered technical modifications:

    Add a serial model “7RC04-CF100005”, and the different is in microphone.

After engineer judgment, the difference does not affect the RF characteristic; the model
was evaluated and deemed as meet the standards requirement, radiated emission test
was considered necessary.

For more detail features, please refer to user's Manual.




1.3 Antenna description

The EUT uses a permanently connected antenna.

Antenna Gain : 0 dBi
Antenna Type : Print antenna
Connector Type : Fixed


                                                            FCC ID. :R8Y7RC04-CF100002

2. Test specifications

2.1 Test standard

The EUT was performed according to the procedures in FCC Part 15 Subpart C
Paragraph 15.249 for non-spread spectrum devices.

The test of radiated measurements according to FCC Part15 Section 15.33(a) had been
conducted and the field strength of this frequency band was all meet limit requirement,
thus we evaluate the EUT pass the specified test.


2.2 Operation mode

The EUT is supplied with DC 3 V from battery and use of individual EUT fixed
frequency, press the power button for continuous emission.

The signal is maximized through rotation and placement in the three orthogonal axes.




            X axis                           Y axis                         Z axis
After verifying three axes, we found the maximum electromagnetic field was
occurred at X axis. The final test data was executed under this configuration.

Radiated emissions were invested cover the frequency range from 30MHz to 1000MHz
using a receiver RBW of 120kHz record QP reading, and the frequency over 1GHz
using a spectrum analyzer RBW of 1MHz and 10Hz VBW record Average reading.
(15.209 paragraph), the Peak reading (1MHz RBW; 3MHz VBW) recorded also on the
report.
The EUT for testing is arranged on a wooden turntable. If some peripherals apply to the
EUT, the peripherals will be connected to EUT and the whole system. During the test,
all cables were arranged to produce worst-case emissions. The signal is maximized
through rotation. The height of antenna and polarization is changing constantly for
exploring for maximum signal level. The height of antenna can be up to 4 meters and

3.3.2 General radiated emission limits

Emissions radiated outside of the specified frequency bands, except for harmonics, shall
be attenuated by at least 50dB below the level of the fundamental or to the general
radiated emission limits in paragraph 15.209, whichever is the lesser attenuation.

Remark:
1. In the above table, the tighter limit applies at the band edges.
2. Distance refers to the distance in meters between the measuring instrument antenna
   and the closed point of any part of the device or system

Measurement uncertainty was calculated in accordance with TR 100 028-1.

          Parameter                    Uncertainty
      Radiated Emission                 ± 5.10 dB
     Conducted Emission                 ± 2.786 dB
This uncertainty represents an expanded uncertainty expressed at approximately the 95
% confidence level using a coverage factor of k=2.

Emissions radiated outside of the specified frequency bands, except for harmonics, shall
be attenuated by at least 50 dB below the level of the fundamental (2410 ~ 2425 MHz)
or to the general radiated emission limits in §15.209, whichever is the lesser attenuation.

6.1 Operating environment

Temperature:                  25    ℃
Relative Humidity:            50    %
Atmospheric Pressure:        1008   hPa


6.2 Test setup & procedure

The 20dB bandwidth was measured using a 50 ohm spectrum analyzer with the
resolutions bandwidth set at 100 kHz, the video bandwidth≧RBW, and the SPAN may
equal to approximately 2 to 3 times the 20dB bandwidth. The test was performed at 3
channels (lowest, middle and highest channel). The maximum 20dB modulation
bandwidth is in the following Table.
