RF exposure limit according to FCC CFR 47 parts 1 and 2 §1.310(e), §2.1091(b). According report 7212319860 of SII FCC ID: XBL-TRANSCEIVER FCC §1.1310 limit of power density for general population/uncontrolled exposure is 1 mW/cm 2 . The EUT is defined as module inside portable device designed to be used so that the radiating structure(s) of the device may be used at 20 centimeters distance from the body of the user. Pt- the transmitted maximum EIRP power = -23.48 dBm = 0.00448871 mW. Peak power density for distance 20 cm is Pt/4πr² = 0.00448871 mW/4π*20² = 8.93*10 -7 mW/cm². That is less than 1 mW/cm² power density limit.

General description: * Note: the customer supplied all information in clause below. The Equipment Under Test (hereinafter: EUT) is a Radio repeater Model Radio repeater (V2.00) intended to be used for receiving and transmitting the cow tag signal. Radio repeater works in the transmitting at 433.9MHz. Radio repeater works with the 24 Volt AC. The tag is attached to a belt and worn around the neck or leg of a cow. The main future of the Transceiver is to receive and transmit the cow tag data. A Cow tags used for Cow monitoring. The tag is counting steps and monitor cow behavior. Type of modulation: FSK Antenna type: Omni. Antenna gain 2.15 dBi. Manufacturer: HYS Model number: 433-RH771-BNC The EUT external view is presented in photo 1. Photo 1.
