ERRATUM
Adopted: September 5, 2008 Released:  September 5, 2008
By the Commission:
1. On August 7, 2008, we released the Commercial Mobile Alert System Third Report and Order 
(CMAS Third Report and Order)1 in which we adopted rules implementing Section 602(b) of the 
Warning, Alert and Response Network Act.2 In this Erratum we adopt today, we take two actions to 
address concerns raised by the Office of Federal Register regarding the publication of the CMAS Third 
Report and Order in the Federal Register.  First, we correct the effective date for the rules adopted in the 
CMAS Third Report and Order.  Second, we correct our rule regarding timing of subscriber notification.   
2. We delete the caption “V. Effective Date” and paragraphs 61 through 64 of the CMAS Third 
Report and Order and revise the second sentence of paragraph 65 in the CMAS Third Report and Order
to read as follows:  “The rules adopted in this Report and Order shall become effective 30 days from 
publication in the Federal Register.”  
3. We also revise Section 10.210 set forth in Appendix C of the CMAS Third Report and Order to 
delete subparagraph (d).
4. Nothing in this Erratum affects the statutory requirement that, by September 8, 2008 (i.e., 30 days 
after the Commission released the CMAS Third Report and Order), Commercial Mobile Service (CMS) 
Providers must submit an election to the Commission indicating whether or not they intend to transmit 
emergency alerts as part of the Commercial Mobile Alert System.3
