FCC ID: 2BBYAOOO001 According to KDB 447498 D04 Interim General RF Exposure Guidance v01 1. 1-mW Test Exemption Per § 1.1307(b)(3)(i)(A), a single RF source is exempt RF device (from the requirement to show data demonstrating compliance to RF exposure limits, as previously mentioned) if the available maximum time-averaged power is no more than 1 ㎽, regardless of separation distance. This exemption applies to all operating configurations and exposure conditions, for the frequency range 100 ㎑ to 100 ㎓, regardless of fixed, mobile, or portable device exposure conditions. This is a standalone exemption, and it cannot be applied in conjunction with any other test exemption. 2. Test Result Mode Frequency Range (㎒) Maximum Average Target Power (㏈m) Maximum Tune up (㏈) Maximum Average Output Power (㏈m) Limit Result (㏈m) (㎽) (㎽) Bluetooth Low Energy 2 402 ~ 2 480 -17 2.5 -14.5 0.035 1 Pass Note ; - Maximum average target power is the manufacturer’s declared rated power. - Maximum average output power = Maximum average target power ( ㏈m) + Maximum tune up (㏈). 3. Conclusion: No SAR is required.
