FCC Part 15, Subpart C, Section 15.247 – DTS Page 101 MSR Radio Module, Model MSR-RTWAVE FCC ID: SU5-MSR-RTWAVE 6.11. RF EXPOSURE REQUIRMENTS [§§ 15.247(e)(i), 1.1310 & 2.1091] The criteria listed in the following table shall be used to evaluate the environmental impact of human exposure to radio-frequency (RF) radiation. FCC 47 CFR § 1.1310: 6.11.1. Method of Measurements Refer to Sections 1.1310, 2.1091 In order to demonstrate compliance with MPE requirements (see Section 2.1091), the following information is typically needed: (1) Calculation that estimates the minimum separation distance (20 cm or more) between an antenna and persons required to satisfy power density limits defined for free space. (2) Antenna installation and device operating instructions for installers (professional/unskilled users), and the parties responsible for ensuring compliance with the RF exposure requirement (3) Any caution statements and/or warning labels that are necessary in order to comply with the exposure limits (4) Any other RF exposure related issues that may affect MPE compliance ULTRATECH GROUP OF LABS File #: VCT-003F15C247 3000 Bristol Circle, Oakville, Ontario, Canada L6H 6G4 March 14, 2008 Tel. #: 905-829-1570, Fax. #: 905-829-8050, Email: vic@ultratech-labs.com, Website: http://www.ultratech-labs.com All test results contained in this engineering test report are traceable to National Institute of Standards and Technology (NIST)
