CDMA2000 1X includes TIA/EIA-95B as a subset and was approved for publishing in July 1999. It provides voice and data capabilities within a standard 1.25 MHz CDMA channel. This RF bandwidth is identical to the legacy IS-95 B system standard. Maximum average conducted powers were measured to ensure worst case power configuration was tested: CONFIGURATION CONDUCTED POWER (dBm) (Full Rate) CDMA 800-BC10 CDMA 800- BC0 CDMA 1900 Ch Ch Ch Ch Ch Ch Ch Ch Ch 476 580 684 1013 384 777 25 600 1175 SO3 RC1 24.87 25.06 24.90 RC3 24.89 25.06 24.91 SO17 RC2 24.90 25.05 24.90 RC54 24.88 25.06 24.91 In all operating modes, the phone was set to rate maximum RF power level and the measurements were performed on low, mid and high channels. The measurement system measures power drift during HAC testing by comparing E/H-field in the same location at the beginning and at the end of measurement. These records were used to monitor stability of power output during tests. Conducted RF power measurements were also performed before and after each HAC measurements to confirm the output power. During tests, the EUT was put in in-call mode and controlled by a CDMA simulator to generate the required signal and power: Protocol: 6 (IS-2000) Radio Configuration: 3 Power Control: All Up Bits Service Option: 3 Vocoder: 8K Enhanced (low) Data Rate: Full © 2012 Comptest Services LLC Page 7 of 25 HAC T-coil Report This report shall not be reproduced except in full, without the written consent of CompTest Services LLC.

Applicant: Kyocera FCC ID: V65C5155A1 Report #: CT-C5155A1-0412-R1 5 SYSTEM VALIDATION & CALIBRATION At the beginning of the HAC T-coil measurement, a 3-phase calibration was performed per Speag instruction to ensure accurate measurement of the voltages and ABM field. Reference input level was also validated and calibrated per C63.19. 5.1 Input Channel Calibration Phase 1: The AMMI audio output was switched off, and a 200 mV_pp symmetric rectangular signal of 1 kHz was generated and internally connected directly to both channels of the sampling unit (coil in, probe in). Phase 2: The AMMI audio output was off, and a 20 mV_pp symmetric 100 Hz signal was internally connected. The signals during phases 1 and 2 were available at the output on the rear panel of the AMMI. The output must however not be loaded in order not to influence the calibration. After the first two phases, the two input channels were both calibrated for absolute measurements of voltages. The resulting factors were displayed above the multimeter window. After phases 1 and 2, the input channels were calibrated to measure exact voltages. © 2012 Comptest Services LLC Page 11 of 25 HAC T-coil Report This report shall not be reproduced except in full, without the written consent of CompTest Services LLC.

Applicant: Kyocera FCC ID: V65C5155A1 Report #: CT-C5155A1-0412-R1 5.2 Probe Calibration Phase 3: a multisine signal covering each third-octave band from 50 Hz to 5 kHz was generated and applied to both audio outputs. The probe was positioned in the center of the AMCC (user point “coil center”) and aligned in the z-direction, the field orientation of the AMCC. The Coil In channel was measuring the voltage over the AMCC internal shunt, which was proportional to the magnetic field in the AMCC. At the same time, the probe in channel samples the amplified signal picked up by the probe coil. The ratio of the two voltages – in each third-octave filter – leads to the calibration factor of the probe over the frequency band of interest for the spectral representation. The Coil signal is scaled in dBV, and the Probe signal is normalized to show dBV at a frequency of 1 kHz. The sensitivity is the ratio at 1 kHz. The frequency response of the probe (subject to an integrator) can be calculated from the difference of the two curves. The calibration result using a AM1DV2 probe is shown in Appendix B. The internal calibration factors of the coil and probe channel are listed. The graphics represent the values (applying the calibration factors from the previous steps) for the probe and coil channel in dB V for each third-octave filter from 100 Hz to 5 kHz. These values are interconnected with a blue line for the probe and a green line for the coil channel. The probe sensitivity in V / (A/m) at 1 kHz is calculated from the values in the chart. -20 dBV in the coil channel corresponds approx. to 1 A/m. The lines are typically horizontal. Deviations around 160 Hz typically result from power line interference, and the slight decay at the higher frequency is a result of the channel frequency response.

Applicant: Kyocera FCC ID: V65C5155A1 Report #: CT-C5155A1-0412-R1 5.3 Reference Input Level ANSI C63.19 requires the use of reference input level of –18dBm0 that correlate to a normal speech input level for CDMA air interface. In order to create the correct level the CMU200 audio codec and the AMMI output were calibrated. 5.3.1 CMU200 Audio Codec Calibration To determine the correct input level, the Encoder/Decorder of the CMU200 base station simulator was calibrated for measured full-scale input voltage level. The CMU200 0dBm0 input reference was determined utilizing the build-in functions of “Decoder Cal” and “Encoder Cal”. CMU200 S/N Modulation Ref.

Applicant: Kyocera FCC ID: V65C5155A1 Report #: CT-C5155A1-0412-R1 6.1 Test Positions The device was placed on a non-conductive phone positioner under the Test Arch. The acoustic output of the EUT was aligned with the center point of the area formed by the dielectric wire and the middle bar of the arch’s top frame. Please refer to Appendix E for the test setup photos. 6.2 Audio Signals During tests signal was fed to the EUT via communication Test set. Proper gain setting was used in software to ensure correct signal level fed to communication test set speech input. The following audio signals were pre-defined by DASY4 and used for calibration and measurements: 48k_voice_1kHz_1 s (duration 1 s): This signal is voice like and has been processed to have a narrow bandwidth mainly within the 1 kHz third-octave band and an even shorter duration of 1 second for faster measurement. This signal passes through a large variety of codecs and permits a direct amplitude and signal quality measurement (S/N) without considerable bandwidth compensation. Its spectrum is shown in a practical measurement in Figure 6.2a.

Applicant: Kyocera FCC ID: V65C5155A1 Report #: CT-C5155A1-0412-R1 Multisine signal 50 Hz – 5 kHz (duration 10 s): Signal with carrier centered in each third-octave band, as used during the calibration. Suited for frequency response measurements. Peak to RMS ratio: 11.1 dB. 48k_voice_300-3000 (duration 2 s): The signal is voice like and has been processed to have a duration of 2 seconds for fast measurement. At the same time, it has a flat spectrum across all third-octave band filters between 300 Hz to 3 kHz and is vanishing at the beginning and end in order to allow longer measurement sequences without transients. It has bandwidth sufficient for frequency response measurements. The spectrum is shown in a practical measurement in fig. 6.2b. The measurement window length of this signal must be set to a multiple of 2 s in order to integrate over the full voice sample. Peak to RMS ratio: 21.6 dB.
