RESEARCH IN MOTIONDocumentRF Exposure Addition To Integrator's Guide Page1(2)Author DataMuhammad DajaniMasud AttayiDate 1998-10-26 Document No.01731-CERT-FCC-SAR-Integrator's Guide(1) FCC CFR 47 Part 90, 1996(2) OET document 65, supplement C, December 1997 Copyright 1998, Research In Motion, LimitedIntroduction:A section explaining RF exposure requirements for integrating the RIM units into otherproducts should be added to the Integrator’s Guide. A draft of this section is includedhere.ComplianceBased on FCC rules(1) 2.1091 and 2.1093 and FCC Guidelines for Human Exposure toRadio frequency Electromagnetic Fields, OET Bulletin 65 and its Supplement C(2), allintegrations of the RIM OEM unit are subject to routine environmental evaluation for RFexposure prior to equipment authorization or use.For portable devices, defined in accordance with FCC rules as a transmitting devicedesigned to be used within 20 cm of the user body under normal operating conditions, RFevaluation must be based on Specific Absorption Rate (SAR) limits in Watts/kg. SAR isa measurement of the rate of energy absorption per unit mass of body tissue.For mobile devices, defined as a transmitting device designed to be generally used suchthat a separation distance of at least 20 cm is maintained between the body of the user andthe transmitting radiated structure, the human exposure to RF radiation can be evaluatedin terms of Maximum Permissible Exposure (MPE) limits for field strength or powerdensity in mWatts/cm2.RIM will submit module specific information and test reports for a generic MPEcompliance. For an end product not covered by RIM testing and submission, theintegrator will submit for a separate FCC ID. The submission should include end productinformation, end product SAR/MPE test report and a reference to RIM module FCC IDfor all other Part 90 requirements.Limits1) SAR limits for General Population/Uncontrolled exposure is 1.6 W/kg for partial bodyexposure, averaged over 1 g of tissue and 4 W/kg for hands, wrists and feet averaged over10 g of tissue. The limits for Occupational/Controlled exposure are more relaxed, i.e., 8W/kg for partial body and 20 W/kg for hands, wrists and feet. The 1.6 W/kg limit appliesfor most of RIM OEM integrators.2) The limit for MPE is 0.6 mW/cm2 at 900 MHz.GuidelinesRF exposure distance is based on normal operating proximity to the user’s body. Thisdistance is measured from the feed point of the antenna to the closest body part. A testneed to be performed to determine the passing distance that meets the exposure limits.

As well the instructions should tell the operator/user to maintain the minimumrequired distance of 20 cm for Austin and 28 cm for Larsen base mounted antennas at alltimes.For the Antenna Company, Eclipse II Magnet Mount antenna with 3 dB gain, all users arerequired to maintain the minimum separation distance of 8 cm from the antenna at alltimes. If the final device configuration cannot be controlled so as to limit the userdistance to the antenna by more than 8 cm then the device or the antenna, requires to havean RF radiation hazard label. This way the users are warned to maintain the minimum 8cm distance from the antenna.
