98Safety GuidelinesFCC Hearing-Aid Compatibility (HAC)Regulations for Wireless DevicesOn July 10, 2003, the U.S. Federal CommunicationsCommission (FCC) Report and Order in WT Docket 01-309 modified the exception of wireless phones underthe Hearing Aid Compatibility Act of 1988 (HAC Act) torequire digital wireless phones be compatible withhearing-aids. The intent of the HAC Act is to ensurereasonable access to telecommunications services forpersons with hearing disabilities. While some wireless phones are used near somehearing devices (hearing aids and cochlear implants),users may detect a buzzing, humming, or whiningnoise. Some hearing devices are more immune thanothers to this interference noise, and phones also varyin the amount of interference they generate.The wireless telephone industry has developed arating system for wireless phones, to assist hearingdevice users find phones that may be compatible withtheir hearing devices. Not all phones have been rated.Phones that are rated have the rating on their box or alabel located on the box. The ratings are not guarantees. Results will varydepending on the user’s hearing device and hearingloss. If your hearing device happens to be vulnerableto interference, you may not be able to use a ratedphone successfully. Trying out the phone with yourhearing device is the best way to evaluate it for yourpersonal needs.M-Ratings: Phones rated M3 or M4 meet FCCrequirements and are likely to generate lessinterference to hearing devices than phones that arenot labeled. M4 is the better/higher of the two ratings.LG GSM phones operate in both the 850 MHz and the1900 MHz bands in the United States. Pursuant to awaiver granted by the FCC, the M rating for thesephones is based on the performance of the phone inthe 1900 MHz band. Hearing aid compatibility in the850 MHz band for GSM phones may or may not be asgood as that obtained in the 1900 MHz band. If thehearing aid compatibility of this phone proves to beunacceptable during initial use, contact yourcommunications service provider for details of theprovider’s return policies.Hearing devices may also be rated. Your hearingdevice manufacturer or hearing health professional
99Safety Guidelinesmay help you find this rating. Higher ratings mean thatthe hearing device is relatively immune to interferencenoise. The hearing aid and wireless phone ratingvalues are then added together. A sum of 5 isconsidered acceptable for normal use. A sum of 6 isconsidered for best use. In the above example, if a hearing aid meets the M2level rating and the wireless phone meets the M3 levelrating, the sum of the two values equal M5. Thisshould provide the hearing aid user with “normalusage” while using their hearing aid with the particularwireless phone. “Normal usage” in this context isdefined as a signal quality that is acceptable fornormal operation. The M mark is intended to be synonymous with the Umark. The T mark is intended to be synonymous withthe UT mark. The M and T marks are recommended bythe Alliance for Telecommunications IndustriesSolutions (ATIS). The U and UT marks are referencedin Section 20.19 of the FCC Rules. The HAC rating andmeasurement procedure are described in theAmerican National Standards Institute (ANSI) C63.19standard.
