2. Presentation Overview This presentation is an introductory overview of the FCC Perspective to Cellphone HAC requirements and recent information released by the FCC regarding this new requirement. Detailed test methods or setups are not covered in this presentation.

3. What does HAC compatibility mean?

4. Historical Perspective � Wireline Phones During the 1970�s changes in audio transducers caused some hearing aids to no longer work with some telephones. In the 1980�s, FCC and IC implemented HAC standards for telephone connecting to the public network as part of Part 68 and CS-03 standards (wireline devices). These standards addressed only H-field performance of the telephone handsets (H-field magnitude, spatial distribution, and frequency response).

5. Historical Perspective - Move Toward Wireless Phones In the 1990�s, new digital technologies were found to cause audible interference in certain hearing aids Mobile phones were exempt from HAC in earlier years due to lack of applicable ratings and measurements standards. The Telecom Act of 1996 mandated compatibility, but not enough action was taken by manufacturers.

6. Historical Perspective � Wireless Devices ANSI C63.19 was approved in 2001 as a relevant rating and measurement standard New FCC regulation as of July 10th 2003 mandated a certain level of availability of HAC handsets � both manufacturers and the carriers must make HAC wireless phone available to individuals using hearing aids.

7. Historical Perspective � Wireless Devices Since 2003, the use of wireless phones has increased dramatically. Wireless phones are used everyday for safety, business and personal use. The FCC has noted that it is more vital than ever for individuals with hearing impairment to have access to digital wireless phones.

8. FCC Implementation Report and Order (R&O) FCC 03-168 removed exemption of certain digital wireless devices therefore making HAC required by certain mobile phones falling under Part 22, 24, and 90. ANSI C63.19-2001 was originally referenced in the associated rules given in 47 CFR section 20.19. Public Notice DA-05-1134A1 accepts an updated standard draft version 2005 of C63.19.

9. FCC Implementation Additionally in June 2005, the FCC reaffirmed the timetable for development and sale of digital wireless phones that are HAC compliant and later on July 11 published a consumer advisory about this.

10. FCC Implementation - Carriers September 16, 2005 The 5 largest U.S. wireless carriers (Sprint, Nextel, Verizon Wireless, Cingular, and T-Mobile) must: Either make 4 HAC handsets available for each air interface or Ensure that 25% of their handset models are HAC compatible. HAC compliance is for RF Emissions Rating M3 to 20.19(b)(1)

11. FCC Implementation � Manuf. September 16, 2005 Each manufacturer of handsets used with public mobile services for use in the United States or imported for use in the United States must: Make 2 HAC handsets per air interface that meet with RF Emissions Rating of M3 to 20.19(b)(1)

12. FCC Implementation - Carriers During 2006 the 5 largest U.S. wireless carriers must: By September 16, 2006 make 5 HAC handsets available for each air interface must be compliant with with RF Emissions Rating of M3 By September 18, 2006 2 Models of each interface must comply with inductive coupling Rating of T3 to 20.19(b)(2)

13. FCC Implementation � Manuf. September 18, 2006 Each manufacturer of handsets used with public mobile services for use in the United States or imported for use in the United States must: 2 Models of each interface must comply with inductive coupling Rating of T3

14. FCC Implementation - Carriers By February 18, 2008, manufactures and carriers alike: Ensure that 50% of their handset models are HAC compliant with RF Emissions Rating of M3 The results based upon our experience with business competition is that individual manufacturers must agree to HAC compatibility now or be shut out of the USA market in the future

15. FCC Implementation There is a legal term described as the �De minimis exception� for certain manufacturers or service provides that offer 2 or fewer handset models in the U.S. These providers are exempt from HAC requirements. But manufacturers that offer 3 or more handset models at any given time must make at least one complaint phone every 2 years.

16. FCC Implementation Much of this information has been published in a consumer advisory for public awareness of the FCC�s position and some implementation dates http://ftp.fcc.gov/cgb/consumerfacts/accessiblewireless.html However, please note that this mainly addresses the carriers and does not adequately address the manufactures.

17. FCC Implementation Manufacturer information can be found in sections 20.19(c) An amendment to 20.19 was published July 27, 2005, in the Federal Register under 70 FR 43325. The effective date is August 28, 2005.
