Introduction This document is prepared to show compliance with the RF Exposure requirements as required in §1.1310 of the FCC Rules and Regulations. The limit for Maximum Permissible Exposure (MPE), specified in FCC §1.1310, is listed in Table 1. According to FCC §1.1310: the criteria listed in the following table shall be used to evaluate the environmental impact of human exposure to radio-frequency (RF) radiation as specified in §1.1307(b). Table 1—Limits for Maximum Permissible Exposure (MPE) f = frequency in MHz. * = Plane-wave equivalent power density. Per the guidance of FCC Rule, Emissions between 9 kHz to 300 kHz should be assessed versus the limits at 300 kHz in Table 1 of Section 1.1310: 614 V/m and 1.63 A/m. 2. Test Set-up CTK Co., Ltd.
