The EUT is powered by 2*AAA 1.5V battery. The EUT has 2 press-buttons. The 2 press-buttons are used to control The RC Car to move forward and backward, turn right and left. Antenna Type: External, Integral For electronic filing, the brief circuit description is saved with filename: description .pdf. 1.2 Test Methodology Radiated emission measurements were performed according to the procedures in ANSI C63.4 (2003). Radiated Emission measurement was performed in a Semi-anechoic chamber. Preliminary scans were performed in the Semi-anechoic chamber only to determine worst case modes. For each scan, the procedure for maximizing emissions in Appendices D and E were followed. All Radiated tests were performed at an antenna to EUT distance of 3 meters, unless stated otherwise in the “Justification Section” of this Application. 1.3 Test Facility The Semi-Anechoic Chamber facility used to collect the radiated data is Intertek Testing Services Shenzhen ltd. Kejiyuan Branch and located at 6F, Block D, Huahan Building, Langshan Road, Nanshan District Shenzhen, P.R.China. This test facility and site measurement data have been fully placed on file with File Number 242492. Report No.: GZ10070342-1 Page 4 of 14 2 System Test Configuration 2.1 Justification The system was configured for testing in a typical fashion (as a customer would normally use it), and in the confines as outlined in ANSI C63.4 (2003). The EUT was powered by 2 new …
