This test report, issued by Shenzhen Huaxia Testing Technology Co., Ltd., details the compliance testing of the JYD-C68 wireless helmet headphones manufactured by Shenzhen Jiayouda Electronics Co., Ltd. The testing was conducted between March 7, 2025, and March 18, 2025, and the report was issued on May 13, 2025. The equipment under test (EUT) was found to comply with the standards specified, including 47 CFR Part 15, Subpart C, KDB558074 D01 15.247 Meas Guidance v05r02, and ANSI C63.10:2013.
The report covers various tests, including antenna requirements, conducted emissions, conducted peak output power, 20dB occupied bandwidth, carrier frequencies separation, hopping channel number, dwell time, band-edge for RF conducted emissions, spurious RF conducted emissions, radiated spurious emission & restricted bands, and other requirements for frequency hopping spread spectrum systems. The EUT utilizes a chip antenna with a gain of 2.7dBi and operates in the 2402MHz to 2480MHz frequency range using Frequency Hopping Spread Spectrum (FHSS) modulation. The test results indicate that the JYD-C68 meets the necessary regulatory requirements for operation.
