SAFETY AND WARRANTY FCC HEARING-AID COMPATIBILITY(HAC) REGULATIONS FORWIRELESS DEVICESOn July 10, 2003, the U.S. Federal Communications Commission(FCC) Report and Order in WT Docket 01-309 modified theexception of wireless phones under the Hearing Aid CompatibilityAct of 1988 (HAC Act) to require digital wireless phones becompatible with hearing-aids. The intent of the HAC Act is toensure reasonable access to telecommunications services for personswith hearing disabilities.While some wireless phones are used near some hearing devices(hearing aids and cochlear implants), users may detect a buzzing,humming, or whining noise. Some hearing devices are moreimmune than others to this interference noise, and phones alsovary in the amount of interference they generate.The wireless telephone industry has developed a rating system forwireless phones, to assist hearing device users find phones that maybe compatible with their hearing devices. Not all phones have beenrated. Phones that are rated have the rating on their box or a labellocated on the box.The ratings are not guarantees. Results will vary depending on theuser’s hearing device and hearing loss. If your hearing devicehappens to be vulnerable to interference, you may not be ableto use a rated phone successfully. Trying out the phone with yourhearing device is the best way to evaluate it for your personalneeds.M-Ratings: Phones rated M3 or M4 meet FCC requirements and arelikely to generate less interference to hearing devices than phonesthat are not labeled. M4 is the better/higher of the two ratings.Hearing devices may also be rated. Yourhearing device manufacturer or hearinghealth professional may help you find thisrating. Higher ratings mean that the hearingdevice is relatively immune to interferencenoise. The hearing aid and wireless phonerating values are then added together. A sum of 5 is consideredacceptable for normal use. A sum of 6 is considered for best use.144
