Notes to 447498 D04 Interim General RF Exposure Guidance:

447498 D04 Interim General RF Exposure Guidance is based on the existing policies and procedures of KDB Publication 447498 D01 v06 with modifications and updates following from the rules adopted in the Second Report and Order in ET Docket No. 03-137 (FCC 19-126; paras. 17 to 118 and Appendix A; 34 FCC Rcd 11697-11742 and 11762-11781).

The effective date for the rule changes in §§ 1.1307, 2.1091, and 2.1093 per FCC 19-126 is May 3, 2021, as stated in Public Notice DA 21-363 (Apr. 2, 2021). Modifications to various other rules adopted in FCC 19 126 went into effect on June 1, 2020.

Existing equipment authorizations remain valid and do not require specific modifications further to the FCC 19-126 rule changes. Certification applications for new and modified equipment must follow the most recent equipment authorization policies and procedures in effect at the time of the application.

This document is not related to the rulemaking in ET Docket No. 19-226 (Notice of Proposed Rulemaking (NPRM) FCC 19-126, paras. 119 to 147 and Appendix B; 34 FCC Rcd 11742-11756 and 11782-11788).

Transition Period until July 31, 2022:

Attachment "447498 D04 Interim General RF Exposure Guidance v01" can be used for equipment authorization and must be used in its entirety along with any other associated revised KDB RF exposure procedures and policies (including FCC-TCB conference presentations).

The previous version, "447498 D01 General RF Exposure Guidance v06," may also be used during the interim period as long as the 731 Form and the related granted application to the FCC are submitted on or before July 31, 2022. "447498 D01 General RF Exposure Guidance v06" must be used entirely (i.e., no mixing of old and new procedures for a certification application(s) filing).

After July 31, 2022, all applications must only use new procedures which will be published as "D01 447498 General RF Exposure Guidance v07", and based on "447498 D04 Interim General RF Exposure Guidance", replacing KDB "447498 General RF Exposure Guidance v06".

The only exception is cases where a certification application(s) includes items subject to Pre-Approval Guidance (PAG, KDB Publication 388624) submitted prior to August 1, 2022. In this case, the TCB can grant the device after the deadline of July 31, 2022, using "447498 General RF Exposure Guidance v06" after the PAG is approved.
