Report No.: BL-HK1950183-402 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. RSS-Gen 6.8 The applicant for equipment certification shall provide a list of all antenna types that may be used with the transmitter, where applicable (i.e. for transmitters with detachable antenna), indicating the maximum permissible antenna gain (in dBi) and the required impedance for each antenna. The test report shall demonstrate the compliance of the transmitter with the limit for maximum equivalent isotropically radiated power (e.i.r.p.) specified in the applicable RSS, when the transmitter is equipped with any antenna type, selected from this list. For expediting the testing, measurements may be performed using only the antenna with highest gain of each combination of transmitter and antenna type, with the transmitter output power set at the maximum level. However, the transmitter shall comply with the applicable requirements under all operational conditions and when in combination with any type of antenna from the list provided in the test report (and in the notice to be included in the user manual, provided below). When measurements at the antenna port are used to determine the RF output power, the effective gain of the device’s antenna shall be stated, based on a measurement or on data from the antenna’s manufacturer. The test report shall state the RF power, output power setting and spurious emission measurements with each antenna type that is used with the transmitter being tested. For licence-exempt equipment with detachable antennas, the user manual shall also contain the following notice in a conspicuous location: This radio transmitter [enter the device’s ISED certification number] has been approved by Innovation, Science and Economic Development Canada to operate with the antenna types listed below, with the maximum permissible gain indicated. Antenna types not included in this list that have a gain greater than the maximum gain indicated for any type listed are strictly prohibited for use with this device. Immediately following the above notice, the manufacturer shall provide a list of all antenna types which can be used with the transmitter, indicating the maximum permissible antenna gain (in dBi) and the required impedance for each antenna type. 11 / 27

Report No.: BL-HK1950183-402 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. RSS-Gen 6.7 The occupied bandwidth or the “99% emission bandwidth” is defined as the frequency range between two points, one above and the other below the carrier frequency, within which 99% of the total transmitted power of the fundamental transmitted emission is contained. The occupied bandwidth shall be reported for all equipment in addition to the specified bandwidth required in the applicable RSSs. In some cases, the “x dB bandwidth” is required, which is defined as the frequency range between two points, one at the lowest frequency below and one at the highest frequency above the carrier frequency, at which the maximum power level of the transmitted emission is attenuated x dB below the maximum in-band power level of the modulated signal, where the two points are on the outskirts of the in-band emission. 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 4.1.1 for test setup description 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 13 / 27

Report No.: BL-HK1950183-402 while the EUT is operating in transmission mode. Use the following spectrum analyzer settings: Span = approximately 2 to 3 times the 20 dB bandwidth RBW ≥ 1% of the 20 dB bandwidth & RBW = 1% to 5% OBW VBW ≥ RBW & VBW = 3* RBW Sweep = auto Detector function = peak Trace = max hold 5.2.4 Test Result Please refer to ANNEX A.1 14 / 27

Report No.: BL-HK1950183-402 5.3 Field Strength of Fundamental Emissions and Radiated Emissions 5.3.1 Limit FCC §15.225(a), (b), (c); RSS-210 B.6 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 suprious 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(dBuV/m) = 20log(X)+40log(30/3)= 20log(15848)+40log(30/3) = 124dBuV 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: Field Strength@30m Field Strength@10m Field Strength@3m Frequency range (MHz) µV/m dBµV/m dBµV/m dBµV/m Below 13.110 30 29.5 48.58 69.5 13.110 ~ 13.410 106 40.5 59.58 80.5 13.410 ~ 13.553 334 50.5 69.58 90.5 13.553 ~13.567 15848 84 103.08 124 13.567 ~ 13.710 334 50.5 69.58 90.5 13.710 ~14.010 106 40.5 59.58 80.5 Above 14.010 30 29.5 48.58 69.5 NOTE: 1. Field Strength (dBµV/m) = 20*log[Field Strength (µV/m)]. 2. In the emission tables above, the tighter limit applies at the band edges. FCC §15.225(d) According to FCC section 15.209 (a), 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 (MHz) Field Strength (µV/m) 0.009 - 0.490 2400/F(kHz) 0.490 - 1.705 24000/F(kHz) 1.705 - 30.0 30 30 - 88 100 88 - 216 150 216 - 960 200 Above 960 500 15 / 27

Report No.: BL-HK1950183-402 Note: 1. For Above 1000 MHz, the emission limit in this paragraph is based on measurement instrumentation employing an average detector, measurement using instrumentation with a peak detector function, corresponding to 20 dB above the maximum permitted average limit. 2. For above 1000 MHz, limit field strength of harmonics: 54dBuV/m@3m (AV) and 74dBuV/m@3m (PK). 5.3.2 Test Setup See section 4.1.1 for test setup description for the antenna port. The photo of test setup please refer to ANNEX B. 5.3.3 Test Procedure The measurement frequency range is from 9 kHz to the 10th harmonic of the fundamental frequency. The Turn Table is actuated to turn from 0° to 360°, and both horizontal and vertical polarizations of the Test Antenna are used to find the maximum radiated power. Mid channels on all channel bandwidth verified. Only the worst RB size/offset presented. The power of the EUT transmitting frequency should be ignored. All Spurious Emission tests were performed in X, Y, Z axis direction. And only the worst axis test condition was recorded in this test report. Use the following spectrum analyzer settings: Span = wide enough to fully capture the emission being measured RBW = 1 MHz for f ≥ 1 GHz, 100 kHz for f < 1 GHz VBW ≥ RBW Sweep = auto Detector function = peak Trace = max hold 5.3.4 Test Result Please refer to ANNEX A.2 NOTE: 1. Results (dBuV/m) = Reading (dBuV) + Factor (dB/m) The reading level is calculated by software which is not shown in the sheet 2. Factor (dB/m) = Antenna Factor (dB/m) + Cable Factor (dB) – Amplifier Gain (dB) 3. Over limit = Results – Limit. 16 / 27

Report No.: BL-HK1950183-402 5.4 Frequency Tolerance 5.4.1 Limit FCC §15.225(e) The frequency tolerance of the carrier signal shall be maintained within ±0.01% of the operating frequency over a temperature variation of −20 degrees to +50 degrees C at normal supply voltage, and for a variation in the primary supply voltage from 85% to 115% of the rated supply voltage at a temperature of 20 degrees C. For battery operated equipment, the equipment tests shall be performed using a new battery. RSS-210 B.6 (a) at the temperatures of -30°C (-22°F), +20°C (+68°F) and +50°C (+122°F), and at the manufacturer’s rated supply voltage; and (b) at the temperature of +20°C (+68°F) and at ±15% of the manufacturer's rated supply voltage. If the frequency stability limits are only met within a temperature range that is smaller than the -30°C to +50°C range specified in (a), the frequency stability requirement will be deemed to be met if the transmitter is automatically prevented from operating outside this smaller temperature range and if the published operating characteristics for the equipment are revised to reflect this restricted temperature range. 5.4.2 Test Setup See section 4.1.1 for test setup description for the antenna port. The photo of test setup please refer to ANNEX B. 5.4.3 Test Procedure 1. The test is performed in a Temperature Chamber. 2.
