China Report No.: BL-SZ2460066-402 5 TEST ITEMS 5.1 Antenna Requirements 5.1.1 Relevant Standards FCC §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 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 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. This requirement does not apply to carrier current devices or to devices operated under the provisions of § 15.211, § 15.213, § 15.217, § 15.219, or § 15.221. Further, this requirement does not apply to intentional radiators that must be professionally installed, such as perimeter protection systems and some field disturbance sensors, or to other intentional radiators which, in accordance with § 15.31(d), must be measured at the installation site. However, the installer shall be responsible for ensuring that the proper antenna is employed so that the limits in this part are not exceeded. 5.1.2 Antenna Anti-Replacement Construction The Antenna Anti-Replacement as following method: Protected Method Description The antenna is embedded in the An embedded-in antenna design is used. product.

R. China Report No.: BL-SZ2460066-402 5.2 Emission Bandwidth 5.2.1 Definition 15.215(c); Intentional radiators operating under the alternative provisions to the general emission limits must be designed to ensure that the 20 dB bandwidth of the emission, or whatever bandwidth may otherwise be specified in the specific rule section under which the equipment operates, is contained within the frequency band designated in the rule section under which the equipment is operated. The following conditions shall be observed for measuring the occupied bandwidth and x dB bandwidth: · The transmitter shall be operated at its maximum carrier power measured under normal test conditions. · The span of the spectrum analyzer shall be set large enough to capture all products of the modulation process, including the emission skirts, around the carrier frequency, but small enough to avoid having other emissions (e.g. on adjacent channels) within the span. · The detector of the spectrum analyzer shall be set to "Sample". However, a peak, or peak hold, may be used in place of the sampling detector since this usually produces a wider bandwidth than the actual bandwidth (worst-case measurement). Use of a peak hold (or "Max Hold") may be necessary to determine the occupied / x dB bandwidth if the device is not transmitting continuously. · The resolution bandwidth (RBW) shall be in the range of 1% to 5% of the actual occupied / x dB bandwidth and the video bandwidth (VBW) shall not be smaller than three times the RBW value. Video averaging is not permitted. Note: It may be necessary to repeat the measurement a few times until the RBW and VBW are in compliance with the above requirement. For the 99% emission bandwidth, the trace data points are recovered and directly summed in linear power level terms. The recovered amplitude data points, beginning at the lowest frequency, are placed in a running sum until 0.5% of the total is reached, and that frequency recorded. The process is repeated for the highest frequency data points (starting at the highest frequency, at the right side of the span, and going down in frequency). This frequency is then recorded. The difference between the two recorded frequencies is the occupied bandwidth (or the 99% emission bandwidth). 5.2.2 Test Setup See section 4.2(Diagram 1) for test setup for the antenna port. The photo of test setup please refer to ANNEX B. 5.2.3 Test Procedure The 20dB bandwidth is measured with a spectrum analyzer connected via a receiver antenna placed near the EUT while the EUT is operating in transmission mode.

China Report No.: BL-SZ2460066-402 5.3 Field Strength of Fundamental Emissions and Radiated Emissions 5.3.1 Limit FCC §15.225(a), (b), (c) According to FCC section 15.225, for <30 MHz, Radiated emissions were measured according to ANSI C63.4. The EUT was set to transmit at the highest output power. The EUT was set 10 meter away from the measuring antenna. The loop antenna was positioned 1 meter above the ground from the center of the loop. The measuring bandwidth was set to 10 kHz. (Note: During testing the receive antenna was rotated about its axis to maximize the emission from the EUT) There was no detected Restricted bands and Radiated spurious emission below 30MHz. The 30m limit was converted to 3m Limit using square factor(x) as it was found by measurements as follows; 3 m Limit(dBµV/m) = 20log(X)+40log(30/3)= 20log(15848)+40log(30/3) = 124dBµV Except as provided elsewhere in this Subpart, the emissions from an intentional radiator shall not exceed the field strength levels specified in the following table: Frequency range (MHz) Below 13.110 13.110 ~ 13.410 13.410 ~ 13.553 13.553 ~13.567 13.567 ~ 13.710 13.710 ~14.010 Above 14.010 Field Strength@30m µV/m dBµV/m 30 29.5 106 40.5 334 50.5 15848 84 334 50.5 106 40.5 30 29.5 Field Strength@10m dBµV/m 48.58 59.58 69.58 103.08 69.58 59.58 48.58 Field Strength@3m dBµV/m 69.5 80.5 90.5 124 90.5 80.5 69.5 NOTE: 1.
