Regulatory Information 129
Somehearingdevicesaremoreimmunethanotherstothisinterferencenoise,andphonesalso
varyintheamountofinterferencenoisetheymaygenerate.ANSIstandardC63.19wasdeveloped
toprovideastandardizedmeansofmeasuringbothwirelessphoneandhearingdevicesto
determineusabilityratingcategoriesforboth.
Ratingshavebeendevelopedformobilephonestoassisthearingdeviceusersfindphonesthat
maybecompatiblewiththeirhearingdevice.Notallphoneshavebeenratedforcompatibilitywith
hearingdevices.Phonesthathavebeenratedhavealabellocatedonthebox.YourALCATEL
ONETOUCHElevatehasanM4/T4rating.
Theseratingsarenotguarantees.Resultswillvarydependingontheuser’shearingdeviceand
individualtypeanddegreeofhearingloss.Ifahearingdeviceisparticularlyvulnerableto
interferencenoise;evenaphonewithahigherratingmaystillcauseunacceptablenoiselevelsin
thehearingdevice.Tryingoutthephonewithyourhearingdeviceisthebestwaytoevaluateitfor
yourpersonalneeds.
M-Ratings:PhonesratedM3orM4meetFCCrequirementsforhearingaidcompatibilityandare
likelytogeneratelessinterferencetohearingdevicesthanunratedphones.(M4isthebetter/higher
ofthetworatings.)
T-Ratings:PhonesratedT3orT4meetFCCrequirementsandarelikelytobemoreusablewitha
hearingdevice’stelecoil(“TSwitch”or“TelephoneSwitch”)thanunratedphones.(T4isthe
better/higherofthetworatings.Notethatnotallhearingdeviceshavetelecoilsinthem.)
Note:NewTechnologies,IncludingWi-Fi.Thisphonehasbeentestedandratedforusewithhearing
aidsforsomeofthewirelesstechnologiesthatituses.However,theremaybenewerwireless
technologies(includingWi-Fi)usedinthisphonethathavenotbeentestedforusewithhearingaids.
Hearingaiddevicesmayalsobemeasuredforimmunitytointerferencenoisefromwirelessphones
andshouldhaveratingssimilartophones.Askyourhearinghealthcareprofessionalfortheratingof
yourhearingaid.Addtheratingofyourhearingaidandyourphonetodetermineprobableusability:
n Anycombinedratingequaltoorgreaterthansixoffersexcellentuse.
n Anycombinedratingequaltofiveisconsiderednormaluse.
n Anycombinedratingequaltofourisconsideredusable.
Thus,ifyoupairanM3hearingaidwithanM3phone,youwillhaveacombinedratingofsixfor
“excellentuse.”ThisissynonymousforTratings.
Itisfurthersuggestedyouexperimentwithmultiplephones(eventhosenotlabeledM3/T3or
M4/T4)whileinthestoretofindtheonethatworksbestwithyourhearingaiddevice.Shouldyou
experienceinterferenceorfindthequalityofserviceunsatisfactoryafterpurchasingyourphone,
promptlyreturnittothestore.Moreinformationabouthearingaidcompatibilitymaybefoundat:
