Telson TDC-8020 CDMA Phone plus SAR data for Nokia 5185 and Telson 8022 Seems to have a MSM Inside at svartifoss2.fcc.gov Outside at svartifoss2.fcc.gov pretty space age looking phone. 5185i SAR data NOKIA MOBILE PHONES 5.3 Specification of position with phone against generic twin phantom The position of the phone relative to the head phantom is shown on page 8. The centre of the phone's earpiece is aligned such that it is co-axial with a mark on the phantom which represents the centre of the ear on the left side of the head. Measurement was done with a Left-Hand (L.H.) side because the helix phone antenna is situated in the top right corner of the phone (viewed from the earpiece side). Therefore, the antenna is closer to the head in the measurement position using a L.H. side rather than a R.H. side. It is concluded that the L.H. side is worst case measurement position. The test signal for measurements was analog AMPS and CDMA (PCS). CDMA mode (Cellular) at the same frequency range than AMPS was not measured due to considerably lower power levels. The phone position against the head was in Normal phone position ( for the IEEE Std C95.1-1991 (ANSI/IEEE) and FCC measurement). The angle between the reference line of the phone and the line connecting both auditory canal opening was 90°. The distance between the handset and the brain simulation liquid was 6mm (page 8). The used radio channels on 900 MHz band were: 991 I 383 and 799. The used radio channels on 1900 MHz band were: 25, 600 and 1175. Peak TX power of analog AMPS and digital CDMA test signal {"Power" in the tables of the paragraph 5.5) was measured from external antenna connector of the transceiver using power level 2. During the tests the battery was fully charged. Ambient and "brain tissue" liquid temperature was 23 °C plus or minus. 1 °C. Telson 8020 SAR COMPLIANCE TESTING OF TELSON MODEL TDC 8020 WIRELESS TELEPHONE I. Introduction The U.S. Federal Communications Commission (FCC) has adopted limits of human exposure to RF emissions from mobile and portable devices that are regulated by the FCC [1]. The FCC has also issued Supplement C (Edition 97-01) to OET Bulletin 65 defining both the measurement and the computational procedures that should be followed for evaluating compliance of mobile and portable devices with FCC limits for human exposure to radiofrequency emissions [2]. The Telson Model TDC 8020 shown in Fig. 1 is a dual-mode wireless telephone that operates in the frequency band 825.03 MHz (Channel 001) to 848.97 MHz (Channel 799) for transmit frequencies. It operates in both the AMPS mode with a maximum ERP of 0.417 W (26.2 dBm) and the CDMA mode with a maximum ERP of 0.257 W (24.1 dBm). In the transmit mode, the telephone may be set to the maximum ERP by means of AGC control. Since the power output is higher for the AMPS mode, the SARs were determined for this higher radiated power mode. For SAR compliance testing, we have used the tissue-simulant model of the human head described in [3]. As recommended in [2], the Telson Model TDC 8020 was placed against the left ear with the antenna located towards the front of the head as shown in Fig. 2. This allows the antenna to be in close proximity to the model of the head resulting in higher SARs allowing, thereby, the worst case determination of absorbed energy in the user's head [4]. Also as recommended in [2], the SAR distributions were measured without the model of a hand to determine the worst case SARs. The SAR distributions were measured at the low-frequency end (825.03 MHz - Channel 001), at the midband (836.49 MHz -Channel 383) and at the high-frequency end (848.97 MHz -Channel 799), both for antenna pulled out or left retracted, respectively.
