The data rate was set in 3Mbps for all the test items due to the highest RF output power. a. The EUT has been associated with peripherals and configuration operated in a manner tended to maximize its emission characteristics in a typical application. Frequency range investigated: conduction (5 khz to 3 MHz), radiation (9 khz to the th harmonic of the highest fundamental frequency or to 4 GHz, whichever is lower). Pre-scanned tests, X, Y, Z in three orthogonal panels, and different data rates were conducted to determine the final configuration (X plane as worst plane) from all possible combinations, and the worst mode of radiated spurious emissions is Bluetooth 3Mbps mode, and recorded in this report. b.

2.6 Measurement Results Explanation Example For all conducted test items: The offset level is set in the spectrum analyzer to compensate the RF cable loss and attenuator factor between EUT conducted output port and spectrum analyzer. With the offset compensation, the spectrum analyzer reading level is exactly the EUT RF output level. Example: The spectrum analyzer offset is derived from RF cable loss and attenuator factor. Offset = RF cable loss + attenuator factor. Following shows an offset computation example with cable loss 5 db and db attenuator. Offset(dB) = RF cable loss(db) + attenuator factor(db). = 5 + = 5 (db) SPORTON INTERNTIONL (KUNSHN) INC. Page Number : 3 of 64

3.8.3 Test Procedures. The EUT was placed on a turntable with.8 meter for frequency below GHz and.5 meter for frequency above GHz respectively above ground. 2. The EUT was set 3 meters from the interference receiving antenna, which was mounted on the top of a variable height antenna tower. 3. For each suspected emission, the EUT was arranged to its worst case and then tune the ntenna tower (from m to 4 m) and turntable (from degree to 36 degrees) to find the maximum reading. pre-amp and a high pass filter are used for the test in order to get better signal level to comply with the guidelines. 4. Set to the maximum power setting and enable the EUT transmit continuously. 5. Use the following spectrum analyzer settings: () Span shall wide enough to fully capture the emission being measured; (2) Set RBW= khz for f < GHz, RBW=MHz for f>ghz ; VBW RBW; Sweep = auto; Detector function = peak; Trace = max hold for peak (3) For average measurement: use duty cycle correction factor method per 5.35(c). Duty cycle = On time/ milliseconds On time = N *L +N 2 *L 2 +...+N n- *LN n- +N n *L n Where N is number of type pulses, L is length of type pulses, etc. verage Emission Level = Peak Emission Level + *log(duty cycle) 6. Corrected Reading: ntenna Factor + Cable Loss + Read Level - Preamp Factor = Level Note: The average levels were calculated from the peak level corrected with duty cycle correction factor (-24.79dB) derived from log (dwell time/ms). This correction is only for signals that hop with the fundamental signal, such as band-edge and harmonic. Other spurious signals that are independent of the hopping signal would not use this correction. SPORTON INTERNTIONL (KUNSHN) INC. Page Number : 53 of 64

Duty Cycle Correction Factor Consideration for FH mode: Bluetooth normal hopping rate is 6Hz and reduced to 8Hz in FH mode; due to the reduced number of hopping frequencies, with the same packet configuration the dwell time in each channel frequency within msec period is longer in FH mode than normal mode. In FH mode, the minimum hopping frequencies are, to get the longest dwell time DH5 packet is observed; the period to have DH5 packet completing one hopping sequence is 2.88 ms x channels = 57.6 ms There cannot be 2 complete hopping sequences within ms period, considering the random hopping behavior, maximum 2 hops can be possibly observed within the period. [ms / 57.6ms ] = 2 hops Thus, the maximum possible ON time: 2.88 ms x 2 = 5.76 ms Worst case Duty Cycle Correction factor, which is derived from the maximum possible ON time, x log(5.76 ms/ms) = -24.79 db 3.8.7 Test Result of Radiated Spurious at Band Edges Please refer to ppendix. 3.8.8 Test Result of Radiated Spurious Emission (3MHz ~ th Harmonic) Please refer to ppendix.

3. ntenna Requirements 3.. Standard pplicable If directional gain of transmitting antennas is greater than 6dBi, the power shall be reduced by the same level in db comparing to gain minus 6dBi. The use of a permanently attached antenna or of an antenna that uses a unique coupling to the intentional radiator shall be considered sufficient to comply with the FCC rule. 3..2 ntenna nti-replacement Construction n embedded-in antenna design is used. 3..3 ntenna Gain The antenna peak gain of EUT is less than 6 dbi. Therefore, it is not necessary to reduce maximum peak output power limit. SPORTON INTERNTIONL (KUNSHN) INC. Page Number : 62 of 64
