Note : This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures : - Reorient or relocate the receiving antenna. - Increase the separation between the equipment and receiver. - Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. - Consult the dealer or an experienced radio/TV technician for help.

TEST SYSTEM CONFIGURATION 3.1 Operation environment TemperatureHumidityPressure 10m Chamber : 22.0C 57 %- Shielded room :24.0C58 %998hPa 3.2 Measurement Uncertainty All measurements involve certain levels of uncertainties, specifically in field of EMC. The factors contributing to uncertainties are test receiver, Cable loss, antenna factor calibration, Antenna directivity, antenna factor variation with height, antenna phase center variation, antenna Frequency interpolation, measurement distance variation, site imperfection, mismatch, and system repeatability. Based on NIS 80,81, The measurement uncertainty level with a 95% confidence level were applied.

The sample calculation is as follows : FS = MR + LF + CL MR = Meter Reading LF = LISN Factor CL = Cable Loss If MR is 30dB, LISN Factor 1dB, CL 1dB The result (MR) is 30 + 1 + 1 = 32dBuV Radiated emission The field strength is calculated by adding the antenna Factor, cable loss and, Antenna pad subtracting the amplifier gain from the measured reading. The sample calculation is as follows : FS = MR + AF + CL + AT -AG MR = Meter Reading AF = Antenna Factor CL = Cable Loss AT = Antenna Pad AG=Amplifier Gain If MR is 30dB, AF 12dB, CL 5dB, AP 10dB, AG 35dB The result (MR) is 30 + 12 + 5 + 10 –35 = 22dBuV/m ERI Electromagnetic research institute 66-6, JEIL-RI, YANGJI-MYUN, YOUNGIN-CITY, KYUNGGI-DO, KOREA TEL: 82 31 336 1186 FAX : 82 31 336 1184 homepage : www.eri.re.kr ReportNo.:ERI-FCC-0141 Page : 7 of 15 4.
