http://www.kctl.co.kr - RF Exposure 1. Regulation According to §15.247(i), 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 of the Commission's guidelines. See § 1.1307(b)(1) of this Chapter. Limits for Maximum Permissive Exposure: RF exposure is calculated.

RF Exposure Compliance Issue The information should be included in the user’s manual: This appliance and its antenna must not be co-located or operation in conjunction with any other antenna or transmitter. A minimum separation distance of 20 ㎝ must be maintained between the antenna and the person for this appliance to satisfy the RF exposure requirements. 3.
