NCEE Labs R032806-01-01 FCC ID: T24-RLR13 IC: 6495A-RLR13 Page 4 of 45 1.2 Test Methods 1.2.1 Conducted Emissions The EUT was powered by 3 AAA batteries and had no connection to the public mains. Conducted emissions measurements were therefore not required on the EUT. 1.2.2 Radiated Emissions Compliance to CFR 47 Parts 15.209 and 15.247 was tested in accordance with the methods of ANSI/IEEE C63.4: 2003. Several configurations were examined and the results presented represent a worst-case scenario. The EUT was placed on a wooden table approximately 80cm high and centered on a 4m diameter turntable. The table was rotated to find the angles of maximum emissions and the receiving antenna was moved from 1m to 4m in both vertical and horizontal positions. The EUT was tested while sitting both vertically and horizontally. The horizontal configuration produced the highest emissions, and that position was used for all radiated testing. All measurements were taken at a distance of 3m from the EUT for Part 15.209 intentional radiator measurements, and 3m for 15.247 measurements of the fundamental frequency in the 902MHz to 928MHz band and subsequent harmonics.
