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.Standard Applicable
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

3750
3750 to 12500
Above 470
12500
375
375 to 1250
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.
6.2.2.Test Procedure
The setup of EUT is according with per ANSI C63.10-2013 measurement procedure. The
specification used was with the FCC Part 15.231(b) and FCC Part 15.209 Limit.

Note 1: Testing is carried out with frequency rang 9 kHz to the tenth harmonics. There is the ambient noise
within frequency range 9 kHz ~ 30 MHz, the permissible value is not show in the report.
Note 2: The fundamental frequency is 433.92MHz, so the fundamental and spurious emissions radiated limit
base on the operating frequency 433.92MHz.
Note 3: Peak Measure Level (dBμV/m) = Reading Level (dBμV) + Factor (dB).
AV Measure Level = Peak Measure Level + Duty Cycle Factor.
Factor (dB) = Cable Loss (dB) + Antenna Factor (dB/m) – Pre_Amplifier Gain (dB).

6.3. 20dB Bandwidth
6.3.1.Standard Applicable
According to FCC Part 15.231(c), the bandwidth of the emission shall be no wider than 0.25% of the
center frequency for devices operating above 70MHz and below 900MHz. Bandwidth is determined
at the points 20 dB down from the modulated carrier.
6.3.2.Test Procedure
With the EUT’s antenna attached, the EUT’s 20dB Bandwidth power was received by the test
antenna, which was connected to the spectrum analyzer with the START, and STOP frequencies set
to the EUT’s operation band.

6.4. Release Time
6.4.1.Standard Applicable
According to 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
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.Standard Applicable
According to FCC Part 15.231(b) and 15.35(c), 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.
