3.    ANTENNA REQUIREMENTS
Excerpt from §15.203 of the FCC Rules/Regulations:
“An intentional radiator antenna shall be designed to ensure that no antenna other than that
furnished by the responsible party can 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 shall be considered
sufficient to comply with the provisions of this section.”


    The antenna of the device is permanently attached.
    There are no provisions for connection to an external antenna.


Conclusion:
The device unit complies with the requirement of §15.203.

6.2. Radiated Emissions

6.2.1.Test Limit
According to §15.231(b), the field strength of emissions from intentional radiators operated under
this section shall not exceed the following:
 Fundamental Frequency         Field Strength of Fundamental     Field Strength of Spurious Emissions
          (MHz)                      (microvolts/meter)                    (microvolts/meter)
      40.66 - 40.70                            2250                                 225
         70 - 130                              1250                                 125
                                       1                                      1
        130 - 174                          1250 to 3750                           125 to 375
        174 - 260                              3750                                 375
                                      1                                      1
        260 - 470                         3750 to 12500                          375 to 1250
        Above 470                            12500                                  1250
The limits on the field strength of the spurious emissions in the above table are based on the
fundamental frequency of the intentional radiator. Spurious emissions shall be attenuated to the
average (or, alternatively, CISPR quasi-peak) limits shown in this table or to the general limits shown
in §15.209, whichever limit permits a higher field strength.


The emission limit in this paragraph is based on measurement instrumentation employing an
average detector. The provisions in §15.35 for limiting peak emissions apply. Spurious Radiated
Emissions measurements start below or at the lowest crystal frequency.


Compliance with the provisions of §15.205 shall be demonstrated using the measurement
instrumentation specified in that section.

6.3.1.Test Limit
The bandwidth of the emission shall be no wider than 0.25% of the center frequency for devices
operating above 70 MHz and below 900 MHz. For devices operating above 900 MHz, the emission
shall be no wider than 0.5% of the center frequency.
Bandwidth is determined at the points 20 dB down from the modulated carrier.

6.4. Release Time

6.4.1.Test Limit
FCC 15.231(a), (1) A manually operated transmitter shall employ a switch that will automatically
deactivate the transmitter within not more than 5 seconds of being released.



6.4.2.Test Procedure Used
ANSI C63.10-2013 – Section 7.4



6.4.3.Test Procedure
With the EUT’s antenna attached, the EUT’s output signal was received by the test antenna, which
was connected to the spectrum analyzer. Set the center frequency to 433.92MHz, than set the
spectrum analyzer to Zero Span for the release time reading. During the testing, the switch was
released then the EUT automatically deactivated.

6.5. Duty Cycle

6.5.1.Test Limit
According to FCC Part 15.231(b) and 15.35(e), for pulse operation transmitter, the averaging pulsed
emissions are calculated by peak value of measured emission plus duty cycle factor.



6.5.2.Test Procedure
With the EUT’s antenna attached, the EUT’s output signal was received by the test antenna, which
was connected to the spectrum analyzer. Set the center frequency to 433.92MHz, than set the
spectrum analyzer to Zero Span for the release time reading. During the testing, the switch was
released then the EUT automatically deactivated.
