Grandstream Networks, Inc. FCC ID: YZZUCM6510 2. Technical Test 2. 1 Summary of Test Results The EUT has been tested according to the following specifications: Standard Test Type Result Notes FCC Part 15, Paragraph 15.107 Conducted Test PASS Complies FCC Part 15, Paragraph 15.109 Radiated Test PASS Complies 2. 2 Measurement Uncertainty Where relevant, the following measurement uncertainty levels have been estimated for tests performed on the EUT as specified in CISPR 16-4-2: Measurement Frequency Uncertainty Conducted emissions 0.15MHz~30MHz 1.72 Radiated emissions 30MHz ~ 300MHz 3.88 Radiated emissions 300MHz ~1000MHz 3.86 Radiated emissions 1000MHz ~18000MHz 5.28 This uncertainty represents an expanded uncertainty expressed at approximately the 95% confidence level using a coverage factor of k=2. Consistent with industry standard (e.g. CISPR 22: 2006, clause 11, Measurement Uncertainty) determining compliance with the limits shall be base on the results of the compliance measurement. Consequently the measure emissions being less than the maximum allowed emission result in this be a compliant test or passing test. The acceptable measurement uncertainty value without requiring revision of the compliance statement is base on conducted and radiated emissions being less than UCISPR which is 3.6dB and 5.2dB respectively. KMO values (called ULab in CISPR 16-4-2) is less than UCISPR as shown in the table above. Therefore, MU need not be considered for compliance. 3. Modifications This product is an extension of original report under FCC ID: YZZUCM6510 The applicant declare that the reasons for this Class II permissive change as below: *Add one power adapter（Model：F18W8-120150SPAU）and has the same electrical specification with original power adapter Anything else are the same as before.

Grandstream Networks, Inc. FCC ID: YZZUCM6510 4. Conducted Power Line Test 4. 1 Test Equipment Please refer to Section 8 this report. 4. 2 Test Procedure The EUT and simulators are connected to the main power through a line impedance stabilization network (L.I.S.N.). This provides a 50 ohm/50uH coupling impedance for the measuring equipment. The peripheral devices are also connected to the main power through a LISN that provides a 50ohm/50uH coupling impedance with 50ohm termination. Both sides of A.C. line are checked for maximum conducted interference. In order to find the maximum emission., the relative positions of equipment and all of the interface cables must be changed according to ANSI C63.4:2014 on conducted measurement. Conducted emissions were invested over the frequency range from 0.15MHz to 30MHz using a receiver bandwidth of 9kHz. 4. 3 Test Setup Vertical Reference Ground Plane Test receiver 40cm EUT Peripheral 80cm LISN Horizontal Reference Ground Plane For the actual test configuration, Please refer to the related items – Photos of Testing.

Grandstream Networks, Inc. FCC ID: YZZUCM6510 5. Radiated Emission Test 5. 1 Test Equipment Please refer to Section 8 this report. 5. 2 Test Procedure 1. The EUT was tested according to ANSI C63.4:2014. 2. The EUT, peripherals were put on the turntable which table size is 1m x 1.5 m, table high 0.8 m, and which is 1.5 m high for above 1 GHz. All set up is according to ANSI C63.4:2014 . 3. The frequency spectrum from 9 kHz to 25 GHz was investigated. All readings from 9 kHz to 150 kHz are quasi-peak values with a resolution bandwidth of 200 Hz. All readings from 150 kHz to 30 MHz are quasi-peak values with a resolution bandwidth of 9 KHz. All readings from 30 MHz to 1 GHz are quasi-peak values with a resolution bandwidth of 120 KHz. All readings are above 1 GHz , peak values with a resolution bandwidth of 1 MHz . Measurements were made at 3 meters. 4. The emissions from the EUT were measured continuously at every azimuth by rotating the turntable. The Receiving antenna high is varied from 1 m to 4 m high to find the maximum emission for each frequency. Emissions below 30MHz were measured with a loop antenna while emission above 30MHz were measured using a broadband E-field antenna. 5. Maximizing procedure was performed on the six (6) highest emissions to ensure EUT compliance is with all installation combinations. All data was recorded in the peak detection mode. Quasi-peak readings was performed only when an emission was found to be marginal (within -4 dB of specification limit), and are distinguished with a "QP" in the data table. 6. Each emission was to be maximized by changing the polarization of receiving antenna both horizontal and vertical. In order to find out the max. emission, the relative positions of this transmitter(EUT) was rotated through three orthogonal axes according to the requirements in Section 8 and 13 of ANSI C63.4:2014 5. 3 Radiated Test Setup For Frequencies below 30 MHz 3M EUT Ground Plane 80cm TURN TABLE Test Receiver For the actual test configuration , please refer to the related items – Photos of Testing KMO FCC ID Report Page 10 of 22 Report #: KSZ2016010703J
