1 INTERTEK TESTING SERVICES RF Exposure The equipment under test (EUT) is a Toy RC Orbit Tumbler operating at 2.4G Band. The EUT can be powered by DC 9.0V (1 x 9.0V 6F22 battery). For more detail information pls. refer to the user manual. Antenna Type: Integral antenna. Antenna Gain: 0dBi. The normal radiated output power (e.i.r.p) is: -8.0dBm (tolerance: +/- 3dB). The normal conducted output power is -8.0dBm (tolerance: +/- 3dB). Modulation Type: GFSK. According to the KDB 447498: The Maximum peak radiated emission for the EUT is 87.8 dBμV/m at 3m in the frequency 2416MHz The EIRP = [(FS*D) ^2 / 30] mW = -7.43dBm which is within the production variation. The Minimum peak radiated emission for the EUT is 86.0 dBμV/m at 3m in the frequency 2467MHz The EIRP = [(FS*D) ^2 / 30] mW = -9.23dBm which is within the production variation. The maximum conducted output power specified is -5dBm= 0.316mW The source- based time-averaging conducted output power =0.316* Duty cycle mW <0.316 mW(Duty cycle <100%) The SAR Exclusion Threshold Level: = 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz) = 3.0 * 5 / sqrt (2.467) mW = 9.55 mW Since the source-based time-averaging conducted output power is well below the SAR low threshold level, so the EUT is considered to comply with SAR requirement without testing. The duty cycle is simply the on-time divided by the period: The duration of one cycle = 16.087ms Effective period of the cycle = = 579.7μs = 0.5797ms DC =0.5797ms / 16.087ms =0.0360 or 3.60% FCC ID: XHT-10087-20
