                      8                        Test results
                                               The ambient humidity and temperature of test facility were kept between the range
                                               30-70% and 20.0-25.0 °C respectively. A base station simulator was used to control
                                               the device during the SAR measurement. The DUT was supplied with a fully charged
                                               battery for each measurement.

                                               For head measurement, the DUT was tested with the flip open on the right-hand side,
                                               and the left-hand side of the phantom in two phone positions, cheek (touch) and tilt
                                               (cheek + 15°). The DUT was tested at the lowest, middle and highest frequencies in
                                               the transmission band. The measured 1-gram averaged SAR values of the DUT
                                               towards the head are provided in Table 1.

                                               For body measurement the DUT was tested with the flip in the closed position with
                                               the back (antenna) and front(display) towards the phantom flat section with 15 mm
                                               distance in both speech and data mode. For all modes, the device was tested at the
                                               lowest, middle and highest frequencies in the transmission band. For portable hands
                                               free (PHF) usage the Sony Ericsson head set HPB-60 was connected to the DUT.
                                               The measured 1-gram averaged SAR values of the DUT towards the body are
                                               provided in Table 2.
