1 INTERTEK TESTING SERVICES Analysis Report The equipment under test (EUT) is a Portable Bluetooth Speaker. The EUT can be powered by AC/DC adapter (Input 100-240, 50/60Hz, 1A; Output: 12Vdc, 2.5A). For more detail information pls. refer to the user manual. Modulation Type: GFSK, ∏/4DQPSK, 8DPSK Bluet o oth Version: 2.1 with EDR function and disable the AFH mode Antenn a Type: Integral antenna Antenna Gain: 0dBi The nominal radiated output power (e.i.r.p) specified: 0dBm ( Tolerance: +/- 4dB) The nominal conducted output power specified: 0dBm ( Tolerance: +/- 4dB) Accord ing to the KDB 447498: The worst-case radiated emission for the EUT is 98.5dBμV/m at 3m in the frequency 2.480GHz = [(FS*D) ^2 / 30] mW = 3.27dBm which is within the production variation. The maximun conducted output power specified is 4dBm = 2.5mW The source- based time-averaging conducted output power = 2.5 * Duty cycle mW= 2.1 m W 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 Based on the Bluetooth Specification (BT version: 2.1), transmitter duty cycle is dependent of packet type (DH1, DH3 and DH5). For one period for a pseudo-random hopping through all 79 RF channels, for DH5: One hopset consists of 5 TX slot and 1 RX slot. Duty cycle = 5 / 6 = 0.833 This requirement is according to KDB 865664 D02 FCC ID: ESX4000437
