Report No.: EF/2013/80004 FCC ID: HFS-K7 Issue Date: Aug. 19, 2013 13 MAXIMUM PERMISSIBLE EXPOSURE (MPE) 13.1 Standard Applicable According to §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensure that the public is not exposed to radio frequency energy level in excess of the Com- mission’s guideline. This is a Mobile device, the MPE is required. According to §1.1310 and §2.1091 RF exposure is calculated. Limits for Maximum Permissive Exposure (MPE) Frequency Range Electric Field Magnetic Field Power Density Averaging Time (MHz) Strength (V/m) Strength (A/m) (mW/cm2) (minute) Limits for General Population/Uncontrolled Exposure 0.3-1.34 614 1.63 *(100) 30 1.34-30 824/f 2.19/f *(180/f2 ) 30 30-300 27.5 0.073 0.2 30 300-1500 / / F/1500 30 1500-15000 / / 1.0 30 F = frequency in MHz * = Plane-wave equipment power density Unless otherwise stated the results shown in this test report refer only to the sample(s) tested and such sample(s) are retained for 90 days only. 除非另有說明，此報告結果僅對測試之樣品負責，同時此樣品僅保留90天。本報告未經本公司書面許可，不可部份複製。 This document is issued by the Company subject to its General Conditions of Service printed overleaf, available on request or accessible at www.sgs.com/terms_and_conditions.htm and, for elec- tronic format documents, subject to Terms and Conditions for Electronic Documents at www.sgs.com/terms_e-document.htm.
