DEKRA Testing and Certification S.A.U.TCB Parque Tecnológico de Andalucía Severo Ochoa, 2 & 6 29590 Málaga Spain Date: February 27th, 2019 Report: 58363_WP7610 RF exposure analysis for the equipment – Maximum Antenna Gain Model: WP7610 FCC ID: N7NWP7610 IC: 2417C-WP7610 The device Sierra wireless WP7610 is a module designed to be installed in other devices. This device is to be used only for fixed and mobile applications. If the final product after integration is intended for portable use, new applications and FCC and IC are required. The antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all the persons and must not be co-located or operating in conjunction with any other antenna or transmitter except as under the conditions described KDB 447498 D01 General RF Exposure Guidance.
