Model Name Description Difference BT740-SA BT740-SC Class 1 Bluetooth Data Module Class 1 Bluetooth Data Module CCL Interface Express Subsystem 2.1+EDR. Integrated Antenna CCL Interface Express Subsystem 2.1+EDR. No integrated antenna, only U.FL RF connector for external antenna BT730-SA Class 1 Bluetooth Data Module CSR Unified Stack 2.0EDR. Integrated Antenna. BT730-SC Class 1 Bluetooth Data Module CSR Unified Stack 2.0EDR. No integrated antenna, only U.FL RF connector for external antenna Hardware is the same on all of these modules. Only difference is the Bluetooth firmware installed. The above models, model BT740-SA and BT740-SC were selected as representative ones for the final test and only its data was recorded in this report Specification of the Equipment under Test (EUT) Frequency Range (MHz) Bluetooth Mode RF General Information Ch.

6 2 RF exposure evaluation 2.1 Scope This International Standard applies to electronic and electrical equipment for which no dedicated product- or product family standard regarding human exposure to electromagnetic fields applies. The frequency range covered is 0 Hz to 300 GHz. The object of this generic standard is to provide assessment methods and criteria to evaluate such equipment against basic restrictions or reference levels on exposure of the general public related to electric, magnetic and electromagnetic fields and induced and contact current 2.2 Normative References The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies IEC , International Electrotechnical Vocabulary Chapter 161: Electromagnetic compatibility. Council Recommendation 1999/519/EC of 12 July 1999 on the limitation of exposure of the general public to electromagnetic fields (0 Hz to 300 GHz) (Official Journal L 197 of 30 July 1999). 2.3 Compliance Criteria The electronic and electrotechnical apparatus shall comply with the basic restriction as specified in Annex III of Council Recommendation 1999/519/EC. The reference levels in the Council Recommendation 1999/519/EC on public exposure to electromagnetic fields are derived from the basic restrictions using worst-case assumptions about exposure. If the reference levels are met, then the basic restrictions will be complied with, but if the reference levels are exceeded, that does not necessarily mean that the basic restrictions will not be met. In some situations, it will be necessary to show compliance with the basic restrictions directly, but it may also be possible to derive compliance criteria that allow a simple measurement or calculation to demonstrate compliance with the basic restriction. Often these compliance criteria can be derived using realistic assumptions about conditions under which exposures from a device may occur, rather than the conservative assumptions that underly the reference levels.
