This document presents an RF Exposure Evaluation Report for the Selfie Screen, model numbers T181, T182, T183, T184, T185, and T186, with FCC ID 2BNA6-T181. The evaluation adheres to FCC KDB447498 D01 guidelines for mobile and portable devices, as well as FCC CFR 47 part 1.1310 and 2.1091 concerning radiofrequency radiation exposure limits and evaluation procedures.
The report details the limits for maximum permissible exposure (MPE) as specified in FCC Part 1.1310, outlining both occupational/controlled and general population/uncontrolled exposure scenarios. It includes calculations based on the Friis transmission formula to determine power density and ensure compliance with the established limits. The evaluation considers simultaneous transmission operations, specifically 2.4G WIFI and Bluetooth, and confirms that the sum of the ratios of spatially averaged results remains below the applicable MPE limits.
The results indicate that the Selfie Screen meets the RF exposure requirements, with a calculated value of 0.0291, which is less than the limit of 1.0. Therefore, no specific absorption rate (SAR) requirement is necessary. The report also notes that the EUT is designed to be more than 20cm away from the human body during operation.
