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 9.2 Test Procedure The Spurious RF conducted emissions compliance of RF radiated emission should be measured by following the guidance in ANSI C63.10-2013, For 30MHz-25GHz ,Set RBW=100kHz and VBW= 300KHz in order to measure the peak field strength, and mwasure frequeny range from 30MHz to 25GHz. 9.3 Test Setup 7.4 Test Result PASS All the test modes completed for test.

Page 31 of 32 Report No.:HK1903010348-2E 10 ANTENNA REQUIREMENT Standard Applicable For intentional device, according to FCC 47 CFR Section 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. And according to FCC 47 CFR Section 15.249, if transmitting antennas of directional gain greater than 6dBi are used, the power shall be reduced by the amount in dB that the directional gain of the antenna exceeds 6dBi. Antenna Information The antenna is Ceramic antenna, the directional gains of antenna used for transmitting is 0.00 dBi.
