INTERTEK TESTING SERVICES Analysis Report The equipment under test (EUT) is a RFID data collector. The EUT was powered by a 3.7 VDC fully charged Li-ion rechargeable battery which is charged by USB power adapter with AC 120V, 60Hz input during the test. For more detail information pls. refer to the user manual. For BT(4.0) function and operating frequency is 2402-2480MHz: Modulation Type: GFSK. Antenna Type: Integral antenna Antenna Gain: 2.0dBi The nominal radiated output power (e.i.r.p) specified: 0dBm (Tolerance: +/- 3dB) The nominal conducted output power specified: -2dBm (Tolerance: +/- 3dB) According to the KDB 447498: The maximum radiated emission for the EUT is 96.8dBμV/m at 3m in the frequency 2.440GHz = [(FS*D) ^2 / 30] mW = 1.57dBm which is within the production variation. The minimum radiated emission for the EUT is 95.3dBμV/m at 3m in the frequency 2.480GHz = [(FS*D) ^2 / 30] mW = 0.07dBm which is within the production variation. The maximun conducted output power specified is 1dBm = 1.26mW The source- based time-averaging conducted output power = 1.26 * Duty cycle mW= 1.26 mW The SAR Exclusion Threshold Level: = 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz) = 3.0 * 5 / sqrt (2.480) 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. This requirement is according to KDB 865664 D02 FCC ID: 2AA7KDORADOBT

For RF ID function and operating frequency is 902.75-927.25MHz Modulation Type: DSB-ASK Antenna Type: Integral antenna Antenna Gain: 1.2dBi The Peak nominal radiated emission power (e.r.p) specified: -17.0dBm (Tolerance: +/- 3dB) The Peak nominal conducted output power specified: -16.05dBm (Tolerance: +/- 3dB) According to the KDB 447498: The maximum radiated emission for the EUT is 78.8dBμV/m at 3m in the frequency 914.75MHz = [(FS*D) ^2 / 30] mW-2.15dB = -18.58dBm which is within the production variation. The minimum radiated emission for the EUT is 77.6dBμV/m at 3m in the frequency 902.75Hz = [(FS*D) ^2 / 30] mW-2.15dB = -19.78dBm which is within the production variation. The maximun conducted output power specified is -13.05dBm = 0.05mW The source- based time-averaging conducted output power = 0.05 * Duty cycle mW= 0.05 mW The SAR Exclusion Threshold Level: = 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz) = 3.0 * 5 / sqrt (0.92725) mW = 15.58 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. This requirement is according to KDB 865664 D02 FCC ID: 2AA7KDORADOBT

For both BT(4.0) and RFID are simultaneous transmissions estimated According to the KDB 447498: When both BT(4.0) and RFID are simultaneous transmissions, the maximun conducted output power for BT(4.0) is 1dBm. In the simultaneous transmissions, BT(4.0)’s estimated SAR values: = (max. power of channel, including tune-up tolerance, mW) / (min. test separation distance, mm) * [sqrt(freq. in GHz)/7.5] W/kg = 1.26 / 5*[sqrt (2.480) / 7.5] W/kg = 0.053 W/kg When both BT(4.0) and RFID are simultaneous transmissions, the maximun conducted output power for RFID is -13.05dBm In the simultaneous transmissions, RFID’s estimated SAR values: = (max. power of channel, including tune-up tolerance, mW) / (min. test separation distance, mm) * [sqrt(freq. in GHz)/7.5] W/kg = 0.05 / 5*[sqrt (0.92725) / 7.5] = 0.001 W/kg Sum of 1-g SAR of all simultaneously transmitting antennas in an operating mode: BT(4.0)’s estimated SAR values + RFID’s estimated SAR values = 0.053 + 0.001 W/kg = 0.054W/kg The simultaneous transmissions SAR Evaluation: ≤ 0.4 W/kg This requirement is according to KDB 865664 D02 FCC ID: 2AA7KDORADOBT
