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 - 01 Page 5 of 11 Korea Testing Laboratory Telecommunication Team 222-13, Guro3-dong, Guro-gu, Seoul Korea 152-848 4. Compliant Conditions (Section 15.231) 4.1 Was the EUT used for continuous transmissions, such as voice or video, and data transmission ? [ ] yes, [ x ] no 4.2 Was the EUT manually operated ? [ x ] yes, [ ] no If yes, did the EUT employ a switch that would automatically deactivate the transmitter within not more than 5 seconds of being released ? [ x ] yes, [ ] no 4.3 Was the EUT automatically activated ? [ ] yes, [ x ] no If yes, did the EUT cease transmission within 5 seconds after deactivation ? [ ] yes, [ ] no 4.4 Was the EUT used for periodic transmissions at regular predetermined intervals ? [ ] yes, [ x ] no Ref. Report No. 03 - 341 – 003 - 01 Page 6 of 11 Korea Testing Laboratory Telecommunication Team 222-13, Guro3-dong, Guro-gu, Seoul Korea 152-848 . RADIATED EMISSION MEASUREMENT (Section 15.231) 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 300 MHz, Log-periodic antenna : 200 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…

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 303.8 MHz 51.7 dB + Antenna Factor 13.9 dB/m + Cable Loss 3.3 dB Preamplifier 0.0 dB Distance Correction Factor * 0.0 dB ------------------------------------------------------------------------------------------- = Radiated Emission 68.9 dB/m ( = 2786.1 /m ) * Extrapolated from the measured distance to the specified distance by an inverse linear distance extrapolation.
