FCC ID: V4P-KB-R05 1 INTERTEK TESTING SERVICES Analysis Report The equipment under test (EUT) is a Lenovo 500 Wireless Mouse. The EUT is powered by 2 x 1.5V AAA batteries. For more detail information please refer to the user manual. Modulation Type: GFSK. Antenna Type: Integral antenna Antenna Gain: -0.19dBi. The nominal conducted output power specified: 0.5dBm (Tolerance: +/- 3dB) The nominal radiated output power (EIRP) specified: 0.31dBm (Tolerance: +/- 3dB) According to the KDB 447498: The maximum radiated emission for the EUT is 98.4dBμV/m at 3m in the frequency 2.478GHz = [(FS*D) ^2 / 30] mW = 3.2dBm which is within the production variation. The minimum radiated emission for the EUT is 95.6dBμV/m at 3m in the frequency 2.403GHz = [(FS*D) ^2 / 30] mW = 0.4dBm which is within the production variation. The maximun conducted output power specified is 3.5dBm = 2.24 mW The source- based time-averaging conducted output power = 2.24 * Duty cycle mW= 2.24 mW The SAR Exclusion Threshold Level: = 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz) = 3.0 * 5 / sqrt (2.478) mW = 9.5 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. Transmitter Duty Cycle Calculation The EUT transmit continuously during the test, the duty cycle is 1.
