Kapsch TrafficCom Info Number 801660B Application Author Alastair Malarky Date 2018 06 06 To TUV SUD Canada Inc JANUS™ Interior OBU Family – 801660B MPE & SAR References: FCC: JQU 801660B Industry Canada 2665A-801660B RSS-102, Issue 5 OET Bulletin 65, Edition 97 447498 D01 General RF Exposure Guidance v06 801660B User Manuals The models are MPE and SAR test/evaluation exempt, as shown by calculation herein. Further due to the separation distance achieved by design, no user labelling is required as demonstrated herein. The OBUs comprise a RF emitting PCB, including PCB antenna, inside an enclosure. The minimum distance from the transmit circuit and antenna one the PCB to the external of the enclosure is 5mm. The UUT has a maximum peak EIRP of 0.82 mW (ERP of 0.5mW) and maximum peak conducted output power of 0.4 mW. In the limit, without any directives restricting separation distance to users in the manuals, the most conservative operating separation distance from the human body is 5mm. Note the normal mounting instructions (see user manuals) result in separation distances much greater than this. For separation distances of <20cm SAR is applicable, while for >=20 cm RF exposure (MPE) is applicable. SAR Evaluation Exemption RSS-102 Per RSS-102, 2.5.1 and linearly interpolating for operating frequency into Table 1, at <= 5mm the exemption limit at 915 MHz is 16.24 mW. The units are therefore SAR evaluation exempt. Since the minimum separation distance is achieved by design no user instructions on maintaining separation distance are required. © 2018 Kapsch TrafficCom Canada Inc., all rights reserved.

Kapsch TrafficCom SAR Test Exclusion Exemption KBD 447498 Per KBD 447498, section 4.3.1 (a) the SAR test exemption limit is given by: Where power is maximum conducted power. Applying the formula we obtain: Power (nearest mW) 1 Frequency 0.915 GHz test separation distance 5 mm formula result 0.19 The units are therefore SAR evaluation exempt. Since the minimum separation distance is achieved by design no user instructions on maintaining separation distance are required. © 2018 Kapsch TrafficCom Canada Inc., all rights reserved.
