The following two radios are collocated in the device: BLE (2.4GHz) transmitter – FCC ID DJU626734, IC ID: 2466B-626734 Iridium Satellite Transmitter – FCC ID Q639603N, IC ID: 4629A-9603N The EUT is fixed when operated, with the user no closer than 20cm from the antenna during transmission. Worst case duty cycle operation and antenna gains were considered for this evaluation. PRJ0040425, RM520S, RM540S Nemko USA, Inc. Page 4 of 7 1.4 FCC RF Exposure Exemption 447498 D04 Interim General RF Exposure Guidance v01 was used as a basis for RF exposure requirements. The SAR-Based Exemption per 1.1307(b)(3)(i)(B) was considered for each radio based on the calculations below. Maximum power (P, EIRP) was obtained from the MPE and Test reports for each of the radios being considered. Table 1 below outlines the Maximum Permissible Exposure Limits (MPE). Table 1: FCC Limits for RF Exposure 1.5 TCB Guidance for Collocate Radios Transmitting Simultaneously For all transmitters that operate simultaneously, sum the following ratios of the individual transmitters: - P / Pth for transmitters meeting exclusion thresholds of option B - ERP / ERPth for transmitters meeting exclusion thresholds of option C - RF Exposure measured value / RF Exposure limit for transmitters evaluated through measurement The total must be less than 1.0 - If not then it will require measurements one or more of the excluded transmitters PRJ0040425, RM520S, RM540S Nemko USA, Inc.
