REPORT NO: 09U12855-2 DATE: November 3, 2009 FCC ID: PPD-AR5B95-H IC: 4104A-AR5B95H 6. SYSTEM SPECIFICATIONS The DASY4 system for performing compliance tests consists of the following items: • A standard high precision 6-axis robot (Stäubli RX family) with controller, teach pendant and software. An arm extension for accommodating the data acquisition electronics (DAE). • A dosimetric probe, i.e., an isotropic E-field probe optimized and calibrated for usage in tissue simulating liquid. The probe is equipped with an optical surface detector system. • A data acquisition electronics (DAE) which performs the signal amplification, signal multiplexing, AD-conversion, offset measurements, mechanical surface detection, collision detection, etc. The unit is battery powered with standard or rechargeable batteries. The signal is optically transmitted to the EOC. • The function of the measurement server is to perform the time critical tasks such as signal filtering, control of the robot operation and fast movement interrupts. • A probe alignment unit which improves the (absolute) accuracy of the probe positioning. • A computer operating Windows 2000 or Windows XP. • DASY4 software. • Remote controls with teach pendant and additional circuitry for robot safety such as warning lamps, etc. • The SAM twin phantom enabling testing left-hand and right-hand usage. • The device holder for handheld mobile phones. • Tissue simulating liquid mixed according to the given recipes. • Validation dipole kits allowing to validate the proper functioning of the system.

REPORT NO: 09U12855-2 DATE: November 3, 2009 FCC ID: PPD-AR5B95-H IC: 4104A-AR5B95H 8. LIQUID PARAMETERS CHECK The simulating liquids should be checked at the beginning of a series of SAR measurements to determine of the dielectric parameters are within the tolerances of the specified target values. The relative permittivity and conductivity of the tissue material should be within ± 5% of the values given in the table below. Reference Values of Tissue Dielectric Parameters for Head and Body Phantom (for 150 – 3000 MHz and 5800 MHz) The head tissue dielectric parameters recommended by the IEEE SCC-34/SC-2 in IEEE Standard 1528 have been incorporated in the following table. These head parameters are derived from planar layer models simulating the highest expected SAR for the dielectric properties and tissue thickness variations in a human head. Other head and body tissue parameters that have not been specified in P1528 are derived from the tissue dielectric parameters computed from the 4-Cole-Cole equations and extrapolated according to the head parameters specified in IEEE Standard 1528.

SYSTEM CHECK The system performance check is performed prior to any usage of the system in order to guarantee reproducible results. The system performance check verifies that the system operates within its specifications of ±10%. System Performance Check Measurement Conditions • The measurements were performed in the flat section of the SAM twin phantom filled with Head or Body simulating liquid of the following parameters. • The DASY4 system with an Isotropic E-Field Probe EX3DV4 was used for the measurements. • The dipole was mounted on the small tripod so that the dipole feed point was positioned below the center marking of the flat phantom section and the dipole was oriented parallel to the body axis (the long side of the phantom). The standard measuring distance was 10 mm (above 1 GHz) and 15 mm (below 1 GHz) from dipole center to the simulating liquid surface. • The coarse grid with a grid spacing of 15 mm was aligned with the dipole. For 5 GHz band - The coarse grid with a grid spacing of 10 mm was aligned with the dipole. • Special 7x7x7 fine cube was chosen for cube • Distance between probe sensors and phantom surface was set to 3 mm. For 5 GHz band - Distance between probe sensors and phantom surface was set to 2.5 mm • The dipole input power (forward power) was 250 mW±3%. • The results are normalized to 1 W input power. 450 to 2450 MHz Reference SAR Values for Body-tissue (From SPEAG) Distance Frequency SAR (1g) SAR (10g) SAR (peak) Dipole Type (mm) (MHz) [W/kg] [W/kg] [W/kg] D450V2 15 450 5.01 3.36 7.22 D835V2 15 835 9.71 6.38 14.1 D900V2 15 900 11.1 7.17 16.3 D1450V2 10 1450 29.6 16.6 49.8 D1800V2 10 1800 38.5 20.3 67.5 D1900V2 10 1900 39.8 20.8 69.6 D2000V2 10 2000 40.9 21.2 71.5 D2450V2 10 2450 51.2 23.7 97.6 Page 15 of 25 COMPLIANCE CERTIFICATION SERVICES FORM NO: CCSUP4031B 47173 BENICIA STREET, FREMONT, CA 94538, USA TEL: (510) 771-1000 FAX: (510) 661-0888 This report shall not be reproduced except in full, without the written approval of CCS.

The client provided a special driver and program, CRTU v5.10.25.0, which enable a user to control the frequency and output power of the module. The modes with highest output power channel were chosen for the conducted output power measurement.
