The EUT has been programmed to continuously transmit during test. This operating condition was tested and used to collect the included data. b) The following table is the setting of the receiver Receiver Parameters Attenuation Start Frequency Stop Frequency IF Bandwidth Setting 10 dB 0.15 MHz 30 MHz 9 kHz c) The EUT was placed 0.8 meters from the horizontal ground plane with EUT being connected to the power mains through a line impedance stabilization network (LISN). All other support equipment powered from additional LISN(s). The LISN provide 50 Ohm/ 50uH of coupling impedance for the measuring instrument. d) Interconnecting cables that hang closer than 40 cm to the ground plane shall be folded back and forth in the center forming a bundle 30 to 40 cm long. e) I/O cables that are not connected to a peripheral shall be bundled in the center. The end of the cable may be terminated, if required, using the correct terminating impedance. The overall length shall not exceed 1 m. f) LISN is at least 80 cm from nearest part of EUT chassis. g) For the actual test configuration, please refer to the related Item photographs of the test setup.

The table was rotated 360 degrees to determine the position of the highest radiation. c) The height of the test antenna shall vary between 1m to 4m. Both horizontal and vertical polarizations of the antenna are set to make the measurement. d) If the peak mode measured value compliance with and lower than quasi peak mode limit, the EUT shall be deemed to meet QP limits and then no additional QP mode measurement performed. e) If the peak mode measured value compliance with and lower than average mode limit, the EUT shall be deemed to meet average limits and then no additional average mode measurement performed. f) For the actual test configuration, please refer to the related item EUT test photos. 5.3.3 Test Setup Add:Room 102, 201, Building 2, Yuanwanggu RFID Industrial Park, Tongguan Road, Tianliao Community, Yutang Street, Guangming District, Shenzhen,China Tel: (86-755) 29989321 Fax: (86-755) 29985110 Web:www.sz-hongbiao.com - Page 18 of 49 - Radiated Emission Test-Up Frequency Below 30MHz Report No.: HB20240412002E-01 Radiated Emission Test-Up Frequency 30MHz~1GHz Radiated emission test-up frequency above 1GHz 5.3.4 Test Result Add:Room 102, 201, Building 2, Yuanwanggu RFID Industrial Park, Tongguan Road, Tianliao Community, Yutang Street, Guangming District, Shenzhen,China Tel: (86-755) 29989321 Fax: (86-755) 29985110 Web:www.sz-hongbiao.com - Page 19 of 49 - Report No.: HB20240412002E-01 Below 30MHz EUT: Pressure: Test Mode: Anti-Lost Mini Flashlight 1010 hPa TX Model Name: Test Voltage: Polarization:: BL014 DC 3.7V from battery -- Freq.

Set the center frequency of the instrument to the center frequency of the transmission. Set RBW OBW if possible; otherwise, set RBW to the largest available value. Set VBW RBW. Set detector = peak or average. The zero-span measurement method shall not be used unless both RBW and VBW are > 50/T and the number of sweep points across duration T exceeds 100. (For example, if VBW and/or RBW are limited to 3 MHz, then the zero-span method of measuring duty cycle shall not be used if T 16.7 microseconds.) The transmitter output is connected to the Spectrum Analyzer. We tested according to the zero-span measurement method, 6.0(b) in KDB 558074 D01 DTS Meas Guidance v05r02. The largest availble value of RBW is 8 MHz and VBW is 50 MHz. The zero-span method of measuring duty cycle shall not be used if T 6.25 microseconds. (50/6.25 = 8) The zero-span method was used because all measured T data are > 6.25 microseconds and both RBW and VBW are > 50/T. The RF output of EUT was connected to the spectrum analyzer by RF cable and attenuator. The path loss was compensated to the results for each measurement. Set to the maximum power setting and enable the EUT transmit continuously. The EUT was operating in controlled its channel. Use the following spectrum analyzer settings: Span = Zero Span RBW = 1MHz (the largest available value) VBW = 3MHz ( RBW) Number of points in Sweep >100 Detector function = peak Trace = Clear write Measure Total and Ton Calculate Duty Cycle = Ton / Total 5.7.3 Test Setup EUT Spectrum Analyzer 5.7.4 Test Results Add:Room 102, 201, Building 2, Yuanwanggu RFID Industrial Park, Tongguan Road, Tianliao Community, Yutang Street, Guangming District, Shenzhen,China Tel: (86-755) 29989321 Fax: (86-755) 29985110 Web:www.sz-hongbiao.com EUT: Pressure: Test Mode: Test plots: - Page 34 of 49 - Report No.: HB20240412002E-01 BLE 1M Anti-Lost Mini Flashlight Model Name: 1012 hPa Test Voltage: TX Mode /CH00, CH19, CH39 TX CH 00 BL014 DC 3.7V from battery TX CH 19 Add:Room 102, 201, Building 2, Yuanwanggu RFID Industrial Park, Tongguan Road, Tianliao Community, Yutang Street, Guangming District, Shenzhen,China Tel: (86-755) 29989321 Fax: (86-755) 29985110 Web:www.sz-hongbiao.com - Page 35 of 49 - TX CH 39 Report No.: HB20240412002E-01 EUT: Pressure: Test Mode: Test plots BLE 2M Anti-Lost Mini Flashlight Model Name: 1012 hPa Test Voltage: TX Mode /CH00, CH19, CH39 TX CH 00 BL014 DC 3.7V from battery Add:Room 102, 201, Building 2, Yuanwanggu RFID Industrial Park, Tongguan Road, Tianliao Community, Yutang Street, Guangming District, Shenzhen,China Tel: (86-755) 29989321 Fax: (86-755) 29985110 Web:www.sz-hongbiao.com - Page 36 of 49 - TX CH 19 Report No.: HB20240412002E-01 TX CH 39 Add:Room 102, 201, Building 2, Yuanwanggu RFID Industrial Park, Tongguan Road, Tianliao Community, Yutang Street, Guangming District, Shenzhen,China Tel: (86-755) 29989321 Fax: (86-755) 29985110 Web:www.sz-hongbiao.com - Page 37 of 49 - Report No.: HB20240412002E-01 5.8 Conducted Band Edge 5.8.1 Limit In any 100 kHz bandwidth outside the frequency band in which the spread spectrum or digitally modulated intentional radiator is operating, the radio frequency power that is produced by the intentional radiator shall be at least 20 dB below that in the 100 kHz bandwidth within the band that contains the highest level of the desired power, based on either an RF conducted or a radiated measurement, provided the transmitter demonstrates compliance with the peak conducted power limits. If the transmitter complies with the conducted power limits based on the use of RMS averaging over a time interval, as permitted under paragraph (b)(3) of this section, the attenuation required under this paragraph shall be 30 dB instead of 20 dB. Attenuation below the general limits specified in §15.209(a) is not required. In addition, radiated emissions which fall in the restricted bands, as defined in §15.205(a), must also comply with the radiated emission limits specified in §15.209(a) (see §15.205(c)). 5.8.2 Test Procedure a) Check the calibration of the measuring instrument using either an internal calibrator or a known signal from an external generator. b) Position the EUT without connection to measurement instrument. Turn on the EUT and connect its antenna terminal to measurement instrument via a low loss cable. Then set it to any one measured frequency within its operating range, and make sure the instrument is operated in its linear range. c) Set RBW to 100 kHz and VBW of spectrum analyzer to 300 kHz with a convenient frequency span including 100 kHz bandwidth from band edge. d) Measure the highest amplitude appearing on spectral display and set it as a reference level.
