    Qaphela: Kuzoba khona ukubambezeleka phakathi kwesikhathi lapho isidlulisi sinikwa amandla kanye nokubukeka kwangempela komsindo kokuphumayo komamukeli. Lokhu kubambezeleka ngamabomu kuqeda izithupha zokuvula, futhi kulawulwa uhlelo lokuklolodela ithoni yomshayeli.

Amanothi Okusebenza

Isilawuli ILEVEL YE-AUDIO akufanele sisetshenziselwe ukulawula ivolumu yomamukeli ohlobene. Lokhu kulungiswa kwenzuzo kusetshenziselwa ukufanisa ileveli yokufaka ye-IFBT4 kusiginali engenayo esuka kumthombo womsindo ukuze kuhlinzekwe ukushintshashintsha okugcwele nobubanzi obuguquguqukayo obukhulu, hhayi ukusetha ivolumu yomamukeli ohlobene.

• Uma ileveli yomsindo iphezulu kakhulu — imitha yomsindo izodlula ileveli engu-0 dB njalo kakhulu. Lesi simo singanciphisa ububanzi besignali yomsindo.
• Uma ileveli yomsindo iphansi kakhulu — imitha yomsindo izoba kude kakhulu ngaphansi kwezinga elingu-0 dB. Lesi simo singase sibangele ukuhayiza nomsindo kumsindo, noma ukupompa nokuphefumula kumsindo ongemuva.

Umkhawulo wokufaka uzophatha iziqongo ezingaphezulu kuka-15 dB ngaphezu kokuguquguquka okugcwele, kungakhathaliseki isilungiselelo sokulawula inzuzo. Ukunciphisa ngezikhathi ezithile kuvame ukuthathwa njengokufiselekayo, okubonisa ukuthi inzuzo isethwe ngendlela efanele futhi isidluliseli silungiswe ngokugcwele ukuze kube nesiginali ekahle esilinganisweni somsindo. Amazwi ahlukene ngokuvamile azodinga izilungiselelo ezihlukile zokuzuza okokufaka komsindo, ngakho hlola lokhu kulungiswa njengoba umuntu ngamunye omusha esebenzisa isistimu. Uma abantu abambalwa abahlukene bezosebenzisa isidlulisi futhi singekho isikhathi sokwenza ukulungisa komuntu ngamunye, silungisele izwi elikhulu kunawo wonke.

Isevisi nokulungisa

Uma isistimu yakho ingasebenzi kahle, kufanele uzame ukulungisa noma ukuhlukanisa inkinga ngaphambi kokuba uphethe ngokuthi isisetshenziswa sidinga ukulungiswa. Qiniseka ukuthi uyilandele inqubo yokusetha kanye nemiyalelo yokusebenza. Hlola amakhebuli axhumayo bese udlulela esigabeni sokuxazulula izinkinga kuleli bhukwana. Sincoma kakhulu ukuthi ungazami ukulungisa izisetshenziswa ngokwakho futhi ungazami isitolo sokulungisa sasendaweni ngaphandle kokulungisa okulula. Uma ukulungisa kuyinkimbinkimbi kunocingo oluphukile noma ukuxhuma okuxekethile, thumela iyunithi efektri ukuze ilungiswe futhi isetshenziswe. Ungazami ukulungisa noma yiziphi izilawuli ngaphakathi kwamayunithi. Uma sekusethwe efekthri, izilawuli ezihlukene nezilungisi azikhukhuleki ngenxa yobudala noma ukudlidliza futhi azidingi ukulungiswa kabusha. Akukho ukulungisa ngaphakathi okuzokwenza iyunithi engasebenzi kahle iqale ukusebenza. Umnyango Wenkonzo We-LECTROSONICS uhlomile futhi unabasebenzi bokukhanda ngokushesha okokusebenza kwakho. Ukulungiswa kwewaranti kwenziwa ngaphandle kwenkokhiso ngokuhambisana nemibandela yewaranti. Ukulungisa ngaphandle kwewaranti kukhokhiswa ngenani eliphansi eliphansi kanye nezingxenye nokuthunyelwa. Njengoba kuthatha cishe isikhathi esiningi nomzamo ukunquma ukuthi yini engalungile njengoba kwenza ukulungisa, kukhona inkokhiso yekhotheshini eqondile. Sizokujabulela ukucaphuna cishe izindleko ngefoni zokulungisa ngaphandle kwewaranti.

Amayunithi Abuyiselwayo azolungiswa

Ukuze uthole isevisi efika ngesikhathi, sicela ulandele lezi zinyathelo ezingezansi:

A. UNGABUYISI imishini efekthri ukuze ilungiswe ngaphandle kokuthi uqale ngokusithinta nge-imeyili noma ngocingo. Sidinga ukwazi uhlobo lwenkinga, inombolo yemodeli kanye nenombolo ye-serial yemishini. Sidinga nenombolo yocingo lapho ungafinyelelwa khona ngo-8 AM ukuya ku-4 PM (Isikhathi Esijwayelekile Sentaba sase-US).

B. Ngemva kokuthola isicelo sakho, sizokunikeza inombolo yokugunyazwa ukubuyisela (i-RA). Le nombolo izosiza ukusheshisa ukulungiswa kwakho ngeminyango yethu yokwamukela nokulungisa. Inombolo yokugunyazwa yokubuyisela kufanele iboniswe ngokucacile ngaphandle kwesiqukathi sokuthumela.

C. Pakisha izinto zokusebenza ngokucophelela futhi usithumele kithi, izindleko zokuthumela zikhokhelwa kusengaphambili. Uma kunesidingo, singakunikeza izinto zokupakisha ezifanele. I-UPS ngokuvamile iyindlela engcono kakhulu yokuthumela amayunithi. Amayunithi asindayo kufanele abe “amabhokisi amabili” ukuze ezokuthutha eziphephile.

D. Siphinde sincome ngokuqinile ukuthi ufake umshwalense okokusebenza, njengoba singeke sibe nesibopho sokulahlekelwa noma ukulinyazwa kwempahla oyithumelayo. Yebo, siqinisekisa izisetshenziswa uma sizibuyisela kuwena.
