Intertek Testing Services Shenzhen Ltd. Guangzhou Branch Job No.: 190507011GZU-002 Page: 1 of 2 FCC ID: 2ARER-PA10 RF Exposure Compliance Requirement 1. Standard requirement 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 level 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 0.2m normally can be maintained between the user and the device.

MPE Calculation Method E (V/m)=(30*P*G)0.5/d Power Density: Pd(W/m2)=E2/377 E=Electric Field (V/m) P=Peak RF output Power (W) G=EUT Antenna numeric gain (numeric) d= Separation distance between radiator and human body (m) The formula can be changed to Pd= (30*P*G)/(377*d2) From the peak EUT RF output power, the minimum mobile separation distance, d=0.2m, as well as the gain of the used antenna, the RF power density can be obtained. Output power=20dBm (max. value described by client) 3.
