IIMFUNO ZAMANDLA

ISILUMKO!
Esi sixhobo sisetyenziselwa ngaphakathi kuphela. Esi sixhobo soqeqesho yimveliso yeKlasi S eyenzelwe ukusetyenziswa kwindawo yorhwebo njengendawo yokuqina.

1.  Musa ukusebenzisa esi sixhobo kuyo nayiphi na indawo ukuba ubushushu elawulwa, ezifana kodwa kungaphelelanga kwi igaraji, iiveranda, amagumbi pool, amagumbi okuhlambela, carports okanye ngaphandle. Ukungaphumeleli ukuthobela kungasitshitshisa iwaranti.
2.  Kubalulekile ukuba esi sixhobo sisetyenziswe ngaphakathi kuphela kwigumbi elilawulwa yimozulu. Ukuba esi sixhobo sibonakaliswe kumaqondo okushisa abandayo okanye kwiindawo eziphakamileyo zokufuma, kucetyiswa ngamandla ukuba isixhobo sifudunyezwe kwiqondo lokushisa kwaye sivumele ixesha lokumisa ngaphambi kokusetyenziswa okokuqala.
3.  Ungaze usebenzise esi sixhobo ukuba siwe, sonakalisiwe, okanye singasebenzi kakuhle, sinentambo eyonakeleyo okanye iplagi, ikwi-ad.amp okanye indawo emanzi, okanye untywiliselwe emanzini.

EIIMFUNO ZOMFUNDO
Naluphi na utshintsho kwintambo yombane eqhelekileyo ebonelelweyo inokuphelisa zonke iziqinisekiso zale mveliso. Iiyunithi ezine-LED kunye nePremium ye-LED consoles ziyilelwe ukuba zizenzele kwaye azifuni umthombo wamandla wangaphandle ukuba usebenze. Ngaphandle konikezelo lwamandla lwangaphandle, ixesha lokuqalisa kweconsole linokulibaziseka. Ukongezwa kweTV kunye nezinye izincedisi zeconsole zifuna unikezelo lwamandla lwangaphandle. Ukunikezelwa kwamandla angaphandle kuya kuqinisekisa ukuba amandla anikezelwa kwi-console ngamaxesha onke kwaye ayafuneka xa kusetyenziswa izixhobo zokongeza. Kwiiyunithi ezine-TV edibeneyo (i-Touch), iimfuno zamandla ze-TV zibandakanyiwe kwiyunithi. I-RG6 quad shield coaxial cable ene-'F Type' yofakelo loxinzelelo kwicala ngalinye iya kufuna ukuqhagamshelwa kwiyunithi ye-cardio kunye nomthombo wevidiyo. Iimfuno ezongezelelweyo zamandla azifuneki kwi-add-on TV yedijithali.

120 V UNITS
Iiyunithi zifuna i-VAC eyi-120, i-50-60 Hz kunye ubuncinane ne-15 A isekethe eneengcingo ezizinikezeleyo ezingathathi hlangothi kunye nezinikezelweyo zomhlaba ezingenazo iiyunithi ezingaphezu kwe-4 kwisekethe nganye. Umbhobho wombane kufuneka ube noqhagamshelo lomhlaba kwaye ube nokucwangciswa okufanayo kunye neplagi efakwe kunye neyunithi. Akukho adaptha kufuneka isetyenziswe nale mveliso.

220-240 V UNITS
Iiyunithi zifuna i-220-240 VAC, 50-60 Hz kwaye ubuncinci i-10 A yesekethe eneengcingo ezizinikezeleyo ezingathathi hlangothi nezizinikezeleyo emhlabeni ezingenazo iiyunithi ezingaphezu kwe-4 kwisekethe nganye. Umbhobho wombane kufuneka ube noqhagamshelo lomhlaba kwaye ube nokucwangciswa okufanayo kunye neplagi efakwe kunye neyunithi. Akukho adaptha kufuneka isetyenziswe nale mveliso.

IMIYALELO YOKUQALA
Iyunithi kufuneka isekelwe. Ukuba kufuneka ingasebenzi kakuhle okanye yophuka, ukumiselwa komhlaba kunika indlela yokunganyangeki kumbane wokunciphisa umngcipheko wokothuka kombane. Iyunithi ixhotyiswe ngentambo ene-conductor-grounding conductor kunye neplagi yokumisa. Iplagi kufuneka iplagiswe kwindawo efanelekileyo efakwe ngokufanelekileyo kwaye isekelwe phantsi ngokuhambelana nazo zonke iikhowudi kunye nemimiselo yendawo. Ukuba umsebenzisi akayilandeli le miyalelo yokumisela, umsebenzisi unokuphelisa iwaranti elinganiselweyo yeMatrix.

UKUGCINWA KWAMANDLA / AMAMANDLA ANGAPHANTSI
Zonke iiyunithi ziqwalaselwe ngokukwazi ukungena kwimowudi yokugcina amandla / amandla aphantsi xa iyunithi ingasetyenziswanga ixesha elithile. Ixesha elongezelelweyo lisenokufuneka ukuze le yunithi iphinde isebenze ngokupheleleyo xa sele ingenile kwindlela yamandla aphantsi. Olu phawu lugcina amandla lunokwenziwa ukuba lusebenze okanye luvalwe ngaphakathi 'kwiMowudi yoMphathi' okanye 'iNdlela yobuNjineli.'

I-ADD-ON DIGITAL TV (i-LED, i-PREMIUM LED)
Ukongezwa koomabonakude bedijithali bafuna amandla awongezelelweyo kwaye kufuneka basebenzise unikezelo lwamandla lwangaphandle. I-RG6 coaxial cable ene-'F Type' yofakelo locinezelo iya kufuna ukudityaniswa phakathi komthombo wevidiyo kunye neyunithi nganye eyongeziweyo yedijithali yeTV.

INDIBANO

UKUKHULULA
Khupha izixhobo apho uza kuzisebenzisa khona. Beka ibhokisi kwindawo ethe tyaba. Kucetyiswa ukuba ubeke isigqubuthelo sokukhusela kumgangatho wakho. Ungaze uvule ibhokisi xa ikwicala layo.

AMANQAKU ABALULEKILEYO
Ngexesha lenyathelo ngalinye lendibano, qinisekisa ukuba ZONKE iinkozo kunye neebholiti zikwindawo kwaye zinemisonto engaphelelanga. Iindawo ezininzi ziye zathanjiswa kwangaphambili ukunceda ekudibaneni nasekusetyenzisweni. Nceda ungacimi oku. Ukuba unobunzima, kunconywa ukusetyenziswa kwegrisi ye-lithium.

ISILUMKISO!
Kukho iinkalo ezininzi ngexesha lenkqubo yendibano ekufuneka ingqalelo ekhethekileyo ihlawulwe. Kubaluleke kakhulu ukulandela imiyalelo yendibano ngokuchanekileyo kwaye uqinisekise ukuba zonke iindawo ziqiniswe ngokuqinileyo. Ukuba imiyalelo yendibano ayilandelwa ngokuchanekileyo, izixhobo zinokuba neendawo ezingaqiniswanga kwaye ziya kubonakala zikhululekile kwaye zingabangela ingxolo ecasulayo. Ukuthintela umonakalo kwisixhobo, imiyalelo yendibano kufuneka ihlaziyweviewed kunye namanyathelo okulungisa kufuneka athathwe.

PHAMBI kokuba UQALE

INDAWO YEYUNITHI
Beka iyunithi kumgangatho kunye nomphezulu ozinzile kude nokukhanya kwelanga. Ukukhanya okukhulu kwe-UV kunokubangela ukuguquka kombala kwiiplastiki. Fumana iyunithi yakho kwindawo enamaqondo obushushu apholileyo kunye nokufuma okuphantsi. Nceda ushiye indawo ecacileyo emva kweyunithi ubuncinane eyi-24” (600 mm). Lo mmandla kufuneka ucace kuwo nawuphi na umqobo kwaye unike umsebenzisi indlela ecacileyo yokuphuma kumatshini. Musa ukubeka iyunithi kuyo nayiphi na indawo eya kuvala nayiphi na i-vent okanye ukuvuleka komoya. Iyunithi akufanele ibekwe kwigaraji, ipatio egqunyiweyo, kufuphi namanzi okanye ngaphandle.

UKUNAKALA KWESIXHOBO
Khangela umgangatho, umgangatho ozinzileyo ukuze ubeke iStepper. I-Stepper ineenyawo zokulinganisa eziphantsi kwenkxaso yeenyawo. Ukuba i-Stepper yakho igungqa kwindawo obufuna ukuyisebenzisa, khulula i-lock nut kunyawo lokulungelelanisa kwaye ulungelelanise iinyawo de uzinze. Xa sele ukwinqanaba, tshixa iinyawo zokulungelelanisa ngokuqinisa i-lock nut kwisakhelo.

ISILUMKISO!

Izixhobo zethu zinzima, sebenzisa ukunakekelwa kunye noncedo olongezelelweyo xa kuyimfuneko xa uhamba. Ukungaphumeleli ukulandela le miyalelo kunokubangela ukwenzakala.

UKUSETYENZISWA OKUFANELEKILEYO

UKUNYUKA INYATHELO

1.  Yima emva kweyunithi.
2.  Ngelixa ubambe zombini iziphatho zengalo yangasemva, beka unyawo olunye kwindawo yeenyawo ehambelana nayo. Linda de ime iphedi yeenyawo ime emazantsi okubetha.
3.  Emva koko beka olunye unyawo lwakho kwipedali echaseneyo.
4.  Iyunithi yakho inikezela ngeendawo ezahlukeneyo zeenyawo. Ukuhambisa unyawo lwakho ukuya phambili uninzi lwendawo yeenyawo kwandisa ukuphakama kwenyathelo lakho, okuya kudala ukuziva kufana nomatshini wokunyathela. Ukubeka unyawo lwakho ngasemva kwipadi yeenyawo kunciphisa ukuphakama kwenyathelo lakho kwaye kudala ngakumbi ukuvakala kokutyibilika, okufana nokuhamba kakuhle okanye ukubaleka. Ngalo lonke ixesha qinisekisa ukuba unyawo lwakho lonke lukhuselekile kwindawo yeenyawo. Intshukumo enyovwayo ixhomekeke.
5.  Ukumisela indawo efanelekileyo yokuzilolonga, yima kwi-pedal ngonyawo lwakho kumbindi we-pedal. Gcina amadolo akho egobile kancinci ngamaxesha onke.

UKUSEBENZISA UMSEBENZI WENTLIZIYO
Umsebenzi wezinga lentliziyo kule mveliso awukho isixhobo sonyango. Ngelixa ukubetha kwentliziyo kunokubonelela ngoqikelelo oluhambelana nesantya sentliziyo yakho, akufuneki kuxhomekeke kuyo xa ufundo oluchanekileyo luyimfuneko. Abanye abantu, kubandakanywa nabo bakwinkqubo yokuvuselela intliziyo, banokuzuza ngokusebenzisa enye inkqubo yokubeka iliso kwizinga lentliziyo njengesifuba okanye umtya wesandla. Izinto ezahlukeneyo, kubandakanya intshukumo yomsebenzisi, inokuchaphazela ukuchaneka kokufunda kwesantya sentliziyo yakho. Ukufundwa kwesantya sentliziyo kujongwe kuphela njengoncedo lokuzilolonga ekumiseleni iindlela zokubetha kwentliziyo ngokubanzi. Nceda udibane nogqirha wakho. Beka intende yezandla zakho ngqo kwii-handlebari zokubambelela. Zombini izandla kufuneka zibambe imivalo ukuze ukubetha kwentliziyo yakho ukubhalisa. Kuthatha ukubetha kwentliziyo oku-5 okulandelelanayo (imizuzwana eyi-15-20) ukuze izinga lentliziyo yakho libhalise. Xa ubambe ii-handlebari ze-pulse, musa ukubambelela ngokuqinileyo. Ukubamba iintambo ngokuqinileyo kunokunyusa uxinzelelo lwegazi lakho. Hlala ukhululekile, ubambe iikomityi. Unokuba namava okufunda ngendlela egwenxa ukuba uhlala ubambe ii-handlebari zokubambelela. Qinisekisa ukuba ucoce i-pulse sensors ukuqinisekisa ukuba uqhagamshelwano olufanelekileyo lunokugcinwa.

ISILUMKISO!
Iinkqubo zokujonga izinga lentliziyo zinokungachanekanga. Ukuzilolonga ngokugqithisileyo kunokukhokelela kukwenzakala okukhulu okanye ukufa. Ukuba uziva utyhafile, yeka kwangoko ukwenza umthambo.

UKULONDOLOZA
