Labeling Requirement (Section 15.19) This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interface, and (2) this device must accept any interference received, including interference that may cause undesired operation. 1.1 Location of Label : User’s Guide Manual 1.2 How Applied : Printed 2. Information to User (Section 15.21) The following or similar statements were provided in the manual for user instruction. Please refer page 3 of the attached manual for details. CAUTION : Any changes or modifications in construction of this device which are not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. 3. Special Accessories (Section 15.27) 3.1 Were the special Accessories provided? [ ] 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. 03 - 341 – 003 - 02 Page 5 of 9 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 (Biconical antenna : 30 to 300MHz, Log-periodic antenna : 200 to 1000MHz or Horn Antenna : 1 to 18GHz) was placed at the distance of 1 meter from the EUT. In order to cohere the individual components of the characteristic broadband emission from the receiver(EUT), a RF generator(CW signal) and a log-periodic antenna were used. The frequency and output level of the generator were adjusted for highest observed coherent receiver emissions on the spectrum analyzer with RF amplifier. An attempt was made to maximize the emission level with the various configurations of the EUT. The effect of changing the position of the cable was observed to find the worst case configuration while rotating the table and varying antenna height and it’s polarization. Radiated and spurious emissions were checked from 30 MHz to 3000 MHz according to section 15.33. 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 which produced maximum emission level. Receivin…

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 300.4 MHz 50.6 dB + Antenna Factor 13.8 dB/m + Cable Loss 3.2 dB Preamplifier 30.0 dB Distance Correction Factor * 0.0 dB ------------------------------------------------------------------------------------------- = Radiated Emission 37.6 dB/m ( = 75.9 /m ) * Extrapolated from the measured distance to the specified distance by an inverse linear distance extrapolation.
