This document presents an RF exposure evaluation conducted by Anbotek Compliance Laboratory for a video projector. The evaluation adheres to KDB 447498 D01 guidelines, focusing on mobile and portable devices, and complies with FCC 1.1310 regulations regarding human exposure to radio frequency radiation. The EUT (Equipment Under Test) is identified by FCC ID 2BGRF-KJM-K310 and operates within the 2.402GHz to 2.480GHz (BT/BLE) and 2.412GHz to 2.462GHz (WLAN) frequency bands, as well as various RLAN bands.
The device is categorized as mobile (>20cm separation), with a general population/uncontrolled exposure classification (S=1mW/cm2). The antenna diversity is single antenna, with a maximum gain of -0.68dBi. The evaluation applied is MPE (Maximum Permissible Exposure). The Friis transmission formula is used to calculate power density, and the maximum measured power densities for BDR&EDR and BLE modes are both 0.0004 mW/cm2, well below the limit of 1 mW/cm2. Therefore, no standalone SAR test is required.
