RF Exposure evaluation FCC ID: 2A2MNHCD-1235L1CON Exposure category: General population/uncontrolled environment EUT Type: Production Unit Device Type: Mobile Device 1. Reference According to §1.1307(b)(1), 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 of the Commission’s guidelines. According to §1.1310 and §2.1091 RF exposure is calculated. KDB447498 D01: Mobile and Portable Devices RF Exposure Procedures and Equipment Authorization Policies 2.
