[ ] yes, [ x ] no 3.2 If yes, details for the special accessories are as follows : 3.3 If yes, were the appropriate instructions provided on the first page of the text concerned with the installation of the device? [ ] yes, [ ] no 3.4 Are these accessories provided of the type which can be readily obtained from multiple retail outlets ? [ ] yes, [ ] no And therefore does the manual specify what additional components or accessories are required to used in order to comply with the Rules? [ ] yes, [ ] no Ref. Report No. 04 - 1341 – 014 Page 5 of 8 Korea Testing Laboratory Telecommunication Team 222-13, Guro3-dong, Guro-gu, Seoul Korea 152-848 ?. RADIATED EMISSION MEASUREMENT (Section 15.109) 1. Test Procedure 1.1 Preliminary Testing for Reference Preliminary testing was performed in a KTL absorber-lined room to determine the emission characteristics of the EUT. The EUT was placed on the wooden table which has dimensions of 0.8 meters in height, 1 meter in length and 1.5 meters in width. Receiving antenna (Biconi-Log antenna : 30 to 1000 MHz or Horn Antenna : 1 to 18 GHz) was placed at the distance of 1 meter from the EUT. An attempt was made to maximize the emission level with the various configurations of the EUT. Emission levels from the EUT with various configurations were examined on a spectrum analyzer connected with a RF amplifier and graphed by a plotter. 1.2 Final Radiated Emission Test at an Absorber-Lined Room The final measurement of radiated field strength was carried out in a KTL absorber-lined Room that was listed up at FCC according to the "Radiated Emissions Testing" procedure specified by ANSI C63.4. Based on the test results in preliminary test, measurement was made in same test set up and configuration with 3 orthogonal planes which produced maximum emission level. Receiving antenna was installed at 3-meter distance from the EUT, and was connected to an EMI receiver or spectrum analyzer with a RF amplifier. Turntable was rotated through 360 degrees and receiving antenna height was varied from 1 to 4 meters above the ground plane with horizontal and vertical polarization to read maximum emission level. If necessary, the radiated emission measurements could be performed at a closer distance than specified distance to ensure higher accuracy and their results w…

Sample Calculation The emission level measured in decibels above one microvolt (dB?) was converted into microvolt per meter (?/m) as shown in following sample calculation. For example : Measured Value at 423.22 MHz < 30.0 dB? + Antenna Factor 15.8 dB/m + Cable Loss 2.6 dB - Preamplifier 30.0 dB - Distance Correction Factor * 0.0 dB = Radiated Emission < 18.4 dB?/m (< 8.3?/m) * Extrapolated from the measured distance to the specified distance by an inverse linear distance extrapolation.
