Apa ndipamene labu yoyezetsa ya BTF ndi ukatswiri wake pamayesero a SAR, RF, T-Coil ndi Volume control.
Kuyeza kwa SAR (specific absorption rate) kumakhala makamaka kwa zida zonyamulika, monga mafoni a m'manja, mapiritsi, mawotchi ndi ma laputopu, ndi zina zotero. Kuyesa kwa SAR ndiko tanthauzo la mphamvu ya maginito yamagetsi yotengedwa kapena kudyedwa pagawo lililonse la maselo amunthu. Labu yathu yoyezetsa ya BTF imagwira ntchito poyezetsa SAR ndipo ili ndi zida zokwanira kuti ikwaniritse zofunikira za malo oyeserera, komanso kuwonetsetsa kuti zidazo zikugwirizana ndi malire achitetezo omwe aboma akuwongolera. Pochita kuyezetsa kwa SAR, opanga amatha kutsimikizira kuti zinthu zawo sizikhala pachiwopsezo cha thanzi kwa ogwiritsa ntchito.

Kuyesa kwa HAC Kuyesa malire
Hearing Aid Compatibility (HAC) Ichi ndi chitsimikiziro chakuti mafoni a m'manja sangasokoneze AIDS pafupi kumva pamaso kulankhulana, ndiko kuti, kuyesa maginito maginito kuyenderana kwa mafoni a m'manja ndi kumva AIDS, amene anawagawa magawo atatu: RF, T- coil ndi Volume control test. Tiyenera kuyesa ndikuwunika zikhalidwe zitatu, mtengo woyamba ndi kuchuluka kwa maginito a siginecha yadala (chizindikiro chadongosolo) pakatikati pa ma frequency a audio frequency band, chachiwiri ndikuyankha pafupipafupi kwa siginecha yadala pamawu onse. frequency band, ndipo mtengo wachitatu ndi kusiyana pakati pa mphamvu ya maginito yachidziwitso chadala (chizindikiro cha dongosolo) ndi chizindikiro chosakonzekera (chizindikiro chosokoneza). Muyezo wa HAC ndi ANSI C63.19 (National Standard Method for Measuring the Compatibility of Wireless communication equipment and hearing AIDS in the United States), malinga ndi zomwe wogwiritsa ntchito amatanthauzira kugwirizana kwa mtundu wina wa chithandizo cha makutu ndi mafoni. foni kudzera mumlingo wotsutsana ndi kusokoneza wa chithandizo chakumva komanso mulingo wofananira wa siginecha ya foni yam'manja.

Mayeso a HAC amafuna kuti malire a foni yam'manja yoyesedwa ndi M3 (zotsatira zake zimagawidwa kukhala M1~M4). Kuphatikiza pa HAC, T-coil (mawu omvera) iyeneranso kuyika malire mu T3 (zotsatira zoyesa zimagawidwa mu T1 mpaka T4).
