The modular has one dipole antenna and one spring antenna which comply with the antenna requirement of Section 15.203. (e) The module shall be tested for compliance with the applicable standard in a stand-alone configuration, i.e. the module must not be inside another device during testing. The modular was tested in a standalone configuration apart from host units. (f) The module shall comply with the Category I equipment labeling requirements and CFR § 15.212(a)(1)(vi). The modular has its own FCC ID number. (g) The module shall comply with any applicable FCC RF exposure requirement which are based on the intended use/configurations. Yes, RF cexposure evaluation performed at 20cm. (h) The modular transmitter complies with all applicable FCC rules. Instructions for maintaining compliance are given in the user instructions. Yes If you have any questions, please feel free to contact us at the address shown below Sincerely Name/Title： Aaron Li/General Manager Company: Heltec Automation Technology Co., Ltd Address: 1f, No.54,56,58, Zirui North Street, Gaoxin District, Chengdu, China.

Simultaneous transmission MPE Considerations According to KDB447498: All transmitters and antennas in the host must be either evaluated for MPE compliance, by measurement or computational modeling, or qualify for the standalone MPE test exclusion in section 7.1. 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 modeled or measured field strengths or power density, is ≤ 1.0. This means that: ∑ of MPE ratios ≤ 1.0 Report No.: TBR-C-202406-0198-15 Page: 3 of 5 TB-RF-074-1. 0 5. Standalone MPE Evaluation: LORA(DSS) Worst Maximum MPE Result Mode N TX Freq.
