Model Number: CP-DX70 Desktop TelePresence EDCS # 1401425 1.0: Attestation Statement of Compliance The Cisco Systems Inc CP-DX70 Series desktop TelePresence has been evaluated for Maximum Permissible Exposure in compliance with 47 Code of Federal Regulations 2.1093. The evaluation was in accordance with methodology as referenced in FCC Bulletin OET 65C (rev 01-01). This report serves as the technical analysis of Cisco of the radios in the CP-DX80 series. The technical information referenced for this study was derived from the FCC / Canada test report on the product. For purposes of this study, the evaluation was only done with the worse case antennae for each programmable power level. The limits used for this evaluation are in line with the recommendations of the World Health Organizations (WHO) International Committee on Non Ionizing Radiation Protection (ICNIRP) as well as the American National Standards Institute (ANSI) C95.1. This analysis also complies with the requirements stated in Industry Canada RSS-102 as well as the applicable Australian and New Zealand regulations. _______________________________________________ Allan Beecroft Technical Leader, Cisco Systems Inc 170 W Tasman Dr San Jose, CA 93727 Phone: 408.527.9787 Email: abeecrof@cisco.com 2.0 EUT Description This is a Cisco DX-70 video-capable desktop TelePresence endpoint which contains an 802.11a/b/g/n radio and an 802.15 Bluetooth Ver. 3.0 + EDR Radio.
