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 with a gain of 2dBi, utilizing GFSK modulation. The Bluetooth version is 5.0 BLE in single mode.

The nominal conducted output power is specified at 3.02 dBm (±2dB). According to KDB 447498 D04 Interim General RF Exposure Guidance v01, the maximum conducted output power for the EUT is 5.02dBm in the frequency 2.440GHz, and the minimum is 4.78dBm in the frequency 2.480GHz, both within production variation. The maximum ERP specified is 4.87dBm. Distance to the host shell is also provided.

The report concludes that the conducted output power and effective radiated power (ERP) are well below the SAR low threshold level, indicating compliance with SAR requirements without the need for further testing. FCC ID: 2A942YJSC009.
