Product Information FCC ID 2AZFJ-E0201 Product name Smart LED Bulb Model number E02011, E0202 Model Declaration PCB board, structure and internal of these model(s) are the same, So no additional models were tested. Power supply Input: 100-240V ~, 50/60Hz, 9W Frequency Range 2402MHz ~ 2480MHz Channel Number 40 channels for Bluetooth V5.0(DTS) Channel Spacing 2MHz for Bluetooth V5.0(DTS) Modulation Type GFSK for Bluetooth V5.0(DTS) Bluetooth Version V5.0 Antenna Description PCB Antenna, 1.5dBi(Max.) Hardware version V1.1 Software version V1.0.12 Exposure category General population/uncontrolled environment EUT Type Production Unit Device Type Mobile Devices 2. Evaluation Method Systems operating under the provisions of FCC 47 CFR section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. In accordance with 47 CFR FCC Part 2 Subpart J, section 2.1091 this device has been defined as mobile device whereby a distance of 0.2m normally can be maintained between the user and the device, and below RF Permissible Exposure limit shall comply with. In accordance with KDB447498D01 for Simultaneous transmission MPE test exclusion applies when the sum of the MPE ratios for all simultaneous transmitting antennas incorporated in a host device, based on the calculated/estimated, numerically modelled or measured field strengths or power density, is ≤ 1.0. The MPE ratio of each antenna is determined at the minimum test separation distance required by the operating configurations and exposure conditions of the host device, according to the ratio of field strengths or power density to MPE limit, at the test frequency. Either the maximum peak or spatially averaged results from measurements or numerical simulations may be used to determine the MPE ratios. Spatial averaging does not apply when MPE is estimated using simple calculations based on far-field plane-wave equivalent conditions. The antenna installation and operating requirements for the host device must meet the minimum test separation distances required by all antennas, in both standalone and simultaneous transmission operations, to satisfy compliance.
