Lub suab hu tau nyob ntsiag to heev, yog li koj yuav xav tau tig koj lub ntim kom hnov tau nws. Kuv tau ceeb toom rau koj tias qhov no siv me ntsis txuj ci los ua, thiab tias nws tau sim ntau yam - Kuv tau txais ib puag ncig 50% ua tiav tus nqi siab tshaj plaws nyob rau lub sijhawm tam sim no thaum hu xov tooj hauv kuv lub tsev tsuas yog los ntawm kev hloov kho ntawm kev teeb tsa kev teeb tsa, thiab tau txais tus lej lees paub qhov tseeb yog nyob ntawm tus lej ntawm yam cuam tshuam nrog koj kev sib pauv thiab kev teeb tsa piezo disk, suav nrog cov duab ntawm kab noj hniav txiav hauv daim npav. Kuv tuaj yeem ua haujlwm ntawm qee qhov kev txhim kho rau qhov kev tsim no, vim nws tuaj yeem tau txais kev lees paub ze rau 100% (tau tswj kom ua qhov no tam sim no siv lub khoos phis tawj los tsav daim npav ua tus simulator - rau cov neeg uas muaj txuj ci siab heev, kuv tuaj yeem rov tsim daim npav. tsav lub piezo nrog pseudo sine yoj ntau dua li lub voj voos siv lim PWM cov cim, thiab nce lub suab nrov thiab qhov chaw ib yam nkaus.), Txawm hais tias kuv tej zaum yuav tsis thab ua qhov no tshwj tsis yog leej twg xav tau txais cov ntawv no tsim tawm hauv ntau, (uas kuv tsis ntseeg!). Yog tias koj tseem xav paub yuav ua li cas tus qauv tsim, thiab yog me ntsis ntawm cov thev naus laus zis zoo li kuv, tom qab ntawv txheeb xyuas cov ntawv sau tseg hauv qab no txhawm rau saib yuav ua li cas tag nrho qhov no ua haujlwm. Yog tias koj xav tsis thoob, qhov no tsis ua haujlwm los ntawm lub xov tooj ntawm tes, raws li koj xav tau lub suab hu los ntawm kev sib pauv rau nws kom paub DTMF lub suab nrov tsim tawm, tab sis raws li kuv tau hais, qhov no yog qhov tshiab ntawm kev ua lag luam tshiab tshaj li txoj hauv kev thoob ntiaj teb los hu tus lej-yeej, nws yuav tsum yuav tsum tau sim tshwj tsis yog tias koj yog tiag tiag rau qhov kev sib tw ntawm kev txhim kho tus tsim. Nws tseem cia siab tseem yog cov lus qhia ntxaws rau hauv qee qhov txheej txheem muaj txiaj ntsig zoo xws li tsim cov ntaub thaiv rau cov khoom siv hluav taws xob me me siv daim npav ID thiab tau txais cov duab nraaj zoo sib xws ua tiav. Thaum kawg, cia siab tias nws tseem yuav txhawb qee lub tswv yim rau lwm daim npav lag luam hluav taws xob - yeej muaj qee lub tswv yim uas tib neeg tau xa email rau kuv tus kheej txij li tshaj tawm qhov no tau zoo heev, yog li kuv paub qhov tsawg kawg yog tshwm sim! Lub sijhawm rau koj tam sim no pib tsim koj tus kheej version ntawm lub ntiaj teb kev tshaj lij tshaj plaws ua lag luam daim npav!
