Label Label Location

22 Jan 2007 Equipment Authorization Division Office of Engineering and Technology Federal Communications Commission 7435 Oakland Mills Road Columbia, MD 21046 Ref: FCC ID: UWHE1500 Dear Sirs: InfoSonics Corp. requests acceptance of the labeling proposal described below for cell phone bearing FCC identifier UWHE1500. The subject cell phone are compact handheld models as shown in figure 1, authorized under 47CFR Part 22&24 for GSM mobile services. Figure 1. Because the majority of the cell phone housing is composed of display, speaker, operating controls, camera and a removable battery pack, there is extremely limited space available to attach the required label carrying the FCC identifier. Attaching the label to the battery pack is not acceptable because the battery pack is a removable item. For this reason, InfoSonics Corp. proposes placing the label carrying the FCC identifier inside the battery compartment as shown in figure 2. InfoSonics Corporate Headquarters 5880 Pacific Center Blvd.·San Diego, CA 92121· www.infosonics.com Figure 2. The consumer packaging for these models includes the battery pack as a separate item, NOT installed on the radio. As such, the FCC identifier will be readily visible to the user before the battery pack is installed and whenever the battery pack is removed or replaced. In this location, the label will also be protected from physical abuse and remain readable for the anticipated life of the device. The consumer packaging for these models is a "gift box" which does not allow the transceiver to be seen at time of purchase. In order to meet the requirements of 47CFR Part 2.925 (d), InfoSonics Corp. will add the FCC identifier " UWHE1500" to the outside of the consumer "gift box" packaging. Thank you for your attention to this matter. Yours Sincerely, Abraham Rosler (Executive VP) InfoSonics Corporate Headquarters 5880 Pacific Center Blvd.·San Diego, CA 92121· www.infosonics.com

Additional Calibration Report Probe 0177 28/03/2006 Probe orientation optimisation for testing at the side of upright phantoms Indexsar IXP-050 probe S/N 0177 28/03/06 This procedure is defined in Indexsar Application Note 2006 No. 003 dated (18/03/2006 ). The present Report should be read in conjunction with the full calibration report for this probe - IMMERSIBLE SAR PROBE CALIBRATION REPORT Part Number: IXP – 050 S/N 0177 March 2006. Explanation of procedure System Validation procedures recommended in EN50361 and IEEE1528 require SAR measurements to be made using a dipole placed at the flat, bottom surface of a liquid-filled phantom of 2mm wall thickness. In this simplified test set-up, SAM phantom influences are avoided and the test limits the source polarisation to the plane normal to the probe axis. This is also the source polarisation direction used for calibration of the probes in liquid-filled waveguides, so the system validation check should confirm the probe calibration parameters. The equivalent validation geometry for an upright phantom is a horizontally-aligned dipole placed at the vertical side of a box phantom, when the source polarisation is direction is also normal to the probe axis. Additional uncertainties are introduced in the subsequent testing of handsets. These include the anatomical shaping of the phantom and the possibility that the wireless source has an arbitrary, and possibly unknown, polarisation direction with respect to the phantom and probe. When a dipole is used under a box phantom, the validation source is only tested in the plane of the normal to the probe axis but, for a test at the side of the phantom, the source polarisation can be rotated with respect to the probe axis direction. This configuration therefore tests the system response to a broad range of polarisation directions and tests the full spherical isotropy behaviour of the SAR probe. It is not possible to make a similar check if the probe is vertical in a box with the source polarisation tangential to the phantom bottom. Upright phantom uncertainty assessments make allowance for this full isotropy range, but the results of a validation check are expected to be variable within this range of spherical isotropy. In this Report, additional calibration measurements have been made, which enable the isotropy range for testing at the side to be characterised and optimised. To minimise the uncertainty range, the SAR conversion factor is set to the mid point of the isotropy range. Additional calibration test procedure The dipole is set up and presented to the surface in the same manner as used for the normal validation tests. The facility is presented by the upright holder to position the dipole horizontally, vertically and at intermediate angles. The probe is configured as shown in Figure 1. With a box phantom shape loaded into the SARA2 software, the probe is positioned at the point on the phantom centerline at dipole height. The probe is then moved (in constrained mode) until the tip is at a point 70mm in the X direction. The first step involves measurement of the rotational isotropy of the probe in the configuration of Figure 1. The probe is first aligned to rotate smoothly about the center of the probe tip. The rotational isotropy is measured in 10 degree steps using a facility in the SARA2 software both with the dipole horizontal and with the dipole vertical. The two data sets are compared as in Figure 2.

The behaviour exhibited by the probe as shown by the data in Figure 2 is consistent with findings from a detailed study of probe directivity [1]. By inspection of the data as illustrated in Figure 2, it is possible to find preferred presentation angles for an individual probe, where the variation between horizontal and vertical are least. From Figure 2, a rotation angle of 130 degrees was selected to optimize the response to both horizontal and vertical source orientations. To facilitate the positioning of the probe in the SARA2 robot in this position, a green dot has been machined into the probe connector. This green dot should be aligned with the positive X-axis of the robot (directly away from the robot). With this probe presentation angle, the probe is then aligned using normal SARA2 procedures at the right height and centered on the central laser spot. Following probe re-alignment, a sequence of 2D/3D scans are conducted at the side of the box phantom. With Probe S/N 0177 validation scans were performed in both horizontal and vertical orientations as shown in Table 1. Page 2 of 3 Page 3 of 3 The table shows the average deviation of the results at all the probe orientation angles tested. This figure should be within 10% to be in line with normal validation procedure recommendations.

Tel: +44 (0) 1306 632870 Fax: +44 (0) 1306 631834 e-mail: [email protected] 1. Measurement Conditions Measurements were performed using a box-shaped phantom made of PMMA with dimensions designed to meet the accuracy criteria for reasonably-sized phantoms that do not have liquid capacities substantially in excess of the volume of liquid required to fill the Indexsar upright SAM phantoms used for SAR testing of handsets against the ear. An Anritsu MS4623B vector network analyser was used for the return loss measurements. The dipole was placed in a special holder made of low-permittivity, low-loss materials. This holder enables the dipole to be positioned accurately in the centre of the base of the Indexsar box-phantom used for flat-surface testing and validation checks. The validation dipoles are supplied with special spacers made from a low- permittivity, low-loss foam material. These spacers are fitted to the dipole arms to ensure that, when the dipole is offered up to the phantom surface, the spacing between the dipole and the liquid surface is accurately aligned according to the guidance in the relevant standards documentation. The spacers are rectangular with a central hole equal to the dipole arm diameter and dimensioned so that the longer side can be used to ensure a spacing of 15mm from the liquid in the phantom (for tests at 900MHz and below) and the shorter side can be used for tests at 1800MHz and above to ensure a spacing of 10mm from the liquid in the phantom. The spacers are made on a CNC milling machine with an accuracy of 1/40 th mm but they may suffer wear and tear and need to be replaced periodically. The material used is Rohacell, which has a relative permittivity of approx. 1.05 and a negligible loss tangent. The apparatus supplied by Indexsar for dipole validation tests thus includes: Balanced dipoles for each frequency required are dimensioned according to the guidelines given in IEEE 1528 [1]. The dipoles are made from semi-rigid 50 Ohm co-ax, which is joined by soldering and is gold-plated subsequently. The constructed dipoles are easily deformed, if mis-handled, and periodic checks need to be made of their symmetry. Rohacell foam spacers designed for presenting the dipoles to 2mm thick PMMA box phantoms. These components also suffer wear and tear and should be replaced when the central hole is a loose-fit on the dipole arms or if the edges are too worn to ensure accurate alignment. The standard spacers are dimensioned for use with 2mm wall thickness (additional spacers are available for 4mm wall thickness). 2. Typical SAR Measurement A SAR validation check is performed with the box-phantom located on the SARA2 phantom support base on the SARA2 robot system. Tests are then conducted at a feed power level of approx. 0.25W. The actual power level is recorded and used to normalise the results obtained to the standard input power conditions of 1W (forward power). The ambient temperature is 21 o C +/- 1 o C and the relative humidity is around 40% during the measurements. The phantom is filled with a 900MHz brain liquid using a recipe from [1], which has the following electrical parameters (measured using an Indexsar DiLine kit) at 900MHz: Relative Permittivity 42.5 Conductivity 0.96 S/m The SARA2 software version VPM2.2 is used with an Indexsar probe previously calibrated using waveguides. The 3D measurements made using the dipole at the bottom of the phantom box is shown below: The results, normalised to an input power of 1W (forward power) are typically: Averaged over 1 cm3 (1g) of tissue 10.55 W/kg Averaged over 10cm3 (10g) of tissue 6.80 W/kg These results can be compared with Table 8.1 in [1]. The agreement is within 10%. 3. Dipole impedance and return loss The dipoles are designed to have low return loss ONLY when presented against a lossy-phantom at the specified distance. A Vector Network Analyser (VNA) was used to perform a return loss measurement on the specific dipole when in the measurement-location against the box phantom. The distance was as specified in the standard i.e. 10mm from the liquid (for 900MHz). The Indexsar foam spacers (described above) were used to ensure this condition during measurement. The impedance was measured at the SMA-connector with the network analyser. The following parameters were measured: Dipole impedance at 900 MHz Re{Z} = 49.999 Ω Im{Z} = 631.313 μΩ Return loss at 900MHz -20.416 dB 4. Dipole handling The dipoles are made from standard, copper-sheathed coaxial cable. In assembly, the sections are joined using ordinary soft-soldering. This is necessary to avoid excessive heat input in manufacture, which would destroy the polythene dielectric used for the cable. The consequence of the construction material and the assembly technique is that the dipoles are fragile and can be deformed by rough handling. Conversely, they can be straightened quite easily as described in this report. If a dipole is suspected of being deformed, a normal workshop lathe can be used as an alignment jig to restore the symmetry. To do this, the dipole is first placed in the headstock of the lathe (centred on the plastic or brass spacers) and the headstock is rotated by hand (do NOT use the motor). A marker (lathe tool or similar) is brought up close to the end of one dipole arm and then the headstock is rotated by 0.5 rev. to check the opposing arm. If they are not balanced, judicious deformation of the arms can be used to restore the symmetry. If a dipole has a failed solder joint, the dipole can be fixed down in such a way that the arms are co-linear and the joint re-soldered with a reasonably-powerful electrical soldering iron. Do not use gas soldering irons. After such a repair, electrical tests must be performed as described below. Please note that, beca…
