RF Exposure Report for Wet Dry Vacuum (Bluetooth 5.0)

RF Exposure

This document details the RF exposure assessment for a Wet Dry Vacuum equipped with Bluetooth 5.0 BLE functionality, operating within the 2402-2480MHz frequency range. The device is powered by a DC 21.6V rechargeable battery and charged via a DC 27V adapter. The antenna is a monopole type, utilizing GFSK modulation and possessing a gain of 2dBi.

The nominal conducted output power is specified as 3.16 dBm (±2dB). According to KDB 447498 V07, the maximum conducted output power for the EUT is 5.16dBm at 2.402GHz, while the minimum is 4.61dBm at 2.480GHz, both within production variation. The maximum ERP is calculated as 5.01dBm, equivalent to 3.17mW.

Distance measurements from the Bluetooth antenna to various sides of the host shell are provided. Based on conducted output power and effective radiated power (ERP) being below SAR thresholds, the EUT is considered compliant with SAR requirements without testing. The FCC ID for this device is 2A942YJSC008.
