PAXPMVE209 RF Exposure Exemption Declaration by UL Japan

03 FCC RF Exposure_DSC

This document is a declaration from UL Japan, Inc. regarding the RF exposure compliance of the TPMS (Tire Pressure Monitoring System Transmitter), model PAXPMVE209, manufactured by Pacific Industrial Company, LTD. The declaration states that the device is exempt from RF exposure Specific Absorption Rate (SAR) evaluation. This exemption is based on the device's output power meeting the exclusion limits outlined in KDB 447498D01(v06), a standard that defines exclusion thresholds for portable devices.

The document details the specific criteria from KDB 447498D01(v06) used to determine the exemption. It includes the formula for calculating the exclusion threshold, which considers the maximum power of the channel (including tune-up tolerance), the minimum test separation distance, and the RF channel transmit frequency. The document also specifies that power and distance are rounded to the nearest mW and mm, respectively, before calculation, and the final result is rounded to one decimal place for comparison.

For the PAXPMVE209, the document provides the relevant parameters: a frequency of 433.92 MHz, a minimum separation distance of 5 mm, and a maximum tune-up tolerance of 8.61 mW. Using these values in the formula, the calculated result is 1.13, which is less than the threshold of 3.0 for 1-g SAR. Therefore, the document concludes that no SAR testing is required for the PAXPMVE209.
