Reference No.: WTD19S07047111W FCC ID: 2AT26PR002BT RF Exposure Report Test Requirement: FCC Part 1.1307 Evaluation Method: FCC Part 2.1091 & KDB 447498 D01 General RF Exposure Guidance v06 Requirements Systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy levels in excess limit for maximum permissible exposure. In accordance with 47 CFR FCC Part 2 Subpart J, section 2.1091 this device has been defined as a mobile device whereby a distance of 0.2 m normally can be maintained between the user and the device.

Reference No.: WTD19S07047111W MPE Calculation Method S＝ PG 4   R2 S = power density (in appropriate units, e.g. mW/cm2) P = output power to the antenna (in appropriate units, e.g., mW). G = power gain of the antenna in the direction of interest relative to an isotropic radiator, the power gain factor, is normally numeric gain. R = distance to the center of radiation of the antenna (appropriate units, e.g., cm) From the peak EUT RF output power, the minimum mobile separation distance, R=20cm, as well as the gain of the used antenna, the RF power density can be obtained Antenna Maximum Maximum Power Limit of Antenna Gain Peak Output Peak Output Density Power Density Result Gain (dBi) (numeric) Power (dBm) Power (mW) (mW/cm2) (mW/cm2) -0.58 0.875 0.48 1.12 0.000195 1 Compliance Waltek Services (Shenzhen) Co.,Ltd. http://www.waltek.com.cn
