The measuring distance of 3m shall be used for measurements. The EUT was placed on the top of arotating table 0.8 meter above the ground at a 3 meter semi-anechoic chamber. The table was rotated 360 degrees to determine the position of the highest radiation(Below 1GHz) b. The measuring distance of 3m shall used for measurements. The EUT was placed on the top of a rotating table 1.5 meter above the ground at a 3 meter semi-anechoic chamber. The table was rotated 360 degrees to determine the position of the highest radiation(Above 1GHz) c. The height of the test antenna shall vary between 1m to 4m.Both horizontal and vertical polarization Of the antenna are set to make the measurement. d. The initial step in collecting radiated emission data is a receive peak detector mode. Pre-scanning the measurement frequency range. Significant peaks are then marked and then Quasi Peak detector mode re-measured. e. All readings are peak unless otherwise stated QP in column of Note. Peak denoted that the Peak reading compliance with the QP limits and then QP Mode measurement didn’t perform (Below 1GHz) f. All readings are Peak mode value unless otherwise stated AVG in column of Note. If the Peak mode measured value compliance with the Peak limits and lower than AVG Limits, the EUT shall be deemed to meet Peak & AVG limits and then only Peak mode was measured, but AVG mode didn’t perform.(Above 1GHz) g.

Part 15 of the FCC Rules provides for the operation of low power communication devices without an individual license (e.g., intrusion detectors, pulsed water tank level gauges, etc.), subject to certain requirements. Some of these devices use extremely narrow pulses to generate wideband emissions, which are measured to determine compliance with the rules. These measurements are typically performed with a receiver or spectrum analyzer. Depending on a number of factors (e.g., resolution bandwidth, pulsewidth, etc.), the spectrum analyzer may not always display the true peak value of the measured emission. This effect, called “pulse desensitization,” relates to the capabilities of the measuring instrument. For the measurement and reporting of the true peak of pulsed emissions, it may be necessary to apply a “pulse desensitization correction factor” (PDCF) to the measured value, pursuant to 47 CFR 15.35(a). If using spectrum analyzer to measure pulse signal , it have to make sure the RBW use is at least 2/PW. •When RBW is less than 2/PW , you are able to measure the true peak level of the pulse signal. If this is the case , PDCF is required to compensate to determine true peak value. Pulse desensitization: PW =74850usec,Period=100000usec, Level=A RBW>2/PW=0.027K , PRF=1/T=0.01K , NOTE: 2 / PW < RBW, first don't need b. For the actual test, please refer to the ANSI C63.10,Annex C refer to section 5 for more detail

TRANSMITTER TIMEOUT 6.1 LIMIT In addition, devices operated under the provisions of this paragraph shall be provided with a means For automatically limiting operation so that the duration of each transmission shall not be greater than one second and the silent period between transmissions shall be at least 30 times the duration of the but in no case less than 10 seconds. 6.2 TEST PROCEDURE (1) Put the EUT on the support in its standard position with associated equipment and switched on. (2) Set center frequency of spectrum analyzer = operating frequency. (3) Set the spectrum analyzer as RBW=100kHz, VBW=100kHz, Span=0Hz, Adjust Sweep=120s. (4) record the duration time 6.3 TEST SETUP

AUTOMATICALLY DEACTIVATE 8.1 STANDARD REQUIREMENT In addition, devices operated under the provisions of this paragraph shall be provided with a means for automatically limiting operation so that the duration of each transmission shall not be greater than one second and the silent period between transmissions shall be at least 30 times the duration of the transmission but in no case less than 10 seconds. 8.2 TEST PROCEDURE The EUT was directly connected to the spectrum analyzer and antenna output port as show in the block diagram below. Spectrum Setting : RBW= 100KHz, VBW=300KHz, Sweep time = Auto. Note: (1)Refer to the plot (As Below),We find a automatically limiting operation transmitter shall employ a switch hat will automatically deactivate the transmitteri immediately, within not more than 5 seconds of being released. (2)The EUT is comply with FCC PART 15 clause 15.231(e). automatically limiting operation working mode are pre-tested.and only the worst result is reported. 8.3 TEST SETUP 8.4 TEST RESULTS Each transmission Frequency(MHz) silent period between transmissions(s) time(s) 434 0.09 30 >10s and > 30*(duration of Limit <1s transmission) Result Pass

ANTENNA REQUIREMENT 8.1 STANDARD REQUIREMENT According to the FCC Part 15 Paragraph 15.203, 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 to the intentional radiator shall be considered sufficient to comply with the provisions of this section. This product use a permanent ceramic printed antenna, fulfill the requirement of this section 8.2 EUT ANTENNA The EUT antenna is Omnidirectional antenna.It conforms to the standard requirements.
