This document is a declaration from UL Japan, Inc. stating that the Car Navigation system, model AT2403 (FCC ID: ACJ932AT2403), manufactured by Panasonic Automotive Systems Co., Ltd., is exempt from RF exposure Specific Absorption Rate (SAR) evaluation. The exemption is based on the fact that the maximum time-averaged power or effective radiated power (ERP) of the device is less than or equal to the threshold Pth (mW) as defined by the Code of Federal Regulation title 47 section 1.1307(b)(3)(i)(B).
The document provides the formula used to calculate the threshold Pth, which depends on the separation distance (d) and frequency (f) of the RF sources. It also includes calculations for the WLAN 2.4 GHz band, WLAN 5 GHz band, and Bluetooth (LE and BR/EDR) parts of the device, demonstrating that the maximum time-averaged power or ERP for each part is below the calculated threshold. The document concludes that the device meets the requirements for exemption from SAR evaluation and includes a calculation for simultaneous transmission operations according to KDB447498 D04.
