Linear Technology Corporation (LT C) o lo'o tu'uina atu oloa (s) fa'apipi'i i lalo ole tulaga AS IS:
O lenei pusa fa'ata'ita'i (DEMO BOARD) pusa o lo'o fa'atau atu pe saunia e Linear Technology ua fa'amoemoe e fa'aoga mo FA'AINA'EINA PO'O FA'AMANATU FA'AMATALAGA ma e le'o saunia e le LT C mo le fa'aaogaina faapisinisi. E pei o lea, o le DEMO BOARD o loʻo i totonu atonu e le atoatoa i tulaga o manaʻomia mamanu-, maketi-, ma/poʻo le gaosiga e fesoʻotaʻi ma puipuiga, e aofia ai ae le faʻatapulaʻa i fua faʻatatau o le saogalemu o oloa e masani ona maua i oloa faʻatau pisinisi. I le avea ai o se faʻataʻitaʻiga, o lenei oloa e le pa'ū i totonu o le lautele o le faʻatonuga a le Iuni a Europa i luga o fesoʻotaʻiga eletise ma o lea e ono mafai ai pe le mafai ona ausia manaoga faʻapitoa o le faʻatonuga, poʻo isi tulafono faatonutonu. Afai e le ausia e lenei pusa su'esu'e ia fa'amatalaga o lo'o ta'ua i le tusi lesona DEMO BOARD e mafai ona toe fa'afo'i le pusa i totonu ole 30 aso mai le aso na tu'uina atu ai mo le toe fa'afo'i atoa. O LE FA'AALIGA O LO'O ta'ua muamua, O LE FA'AALIGA FA'AVAE NA FAIA E LE FA'A'OGA I LE FA'A'OGA MA E SU'I AI ISI FA'AVAE UMA, FA'AMATALAGA, FAAMATALAGA, PO'O LE TULAFONO, E A'OFIA AI SO'O SE FA'AALIGA O FA'O'OA'OGA PO'O LE FA'AMATALAGA MO SO'O SE FAIGA FA'AVAE. SE'I TAGATA I LE TULAFONO O LENEI TALA, E LEAI SE ITU AIGA I LE ISI MO SOO SE FAATASI, FAAPITOA, FAATASI, POO LE FAATUPUGA.
O le tagata fa'aoga e nafa uma matafaioi ma noataga mo le taulimaina lelei ma le saogalemu o oloa. E le gata i lea, o le tagata fa'aoga e tu'uina atu le LT C mai tagi uma e tula'i mai i le tagofiaina po'o le fa'aogaina o oloa. Ona o le tatalaina o le fausiaina o le oloa, o le matafaioi a le tagata faʻaoga le faia o soʻo se puipuiga talafeagai uma e tusa ai ma le faʻaaogaina o le eletise. Ia nofouta foi o oloa o loʻo i totonu atonu e le o faʻatulafonoina faʻamaonia pe faʻamaonia e le lala sooupu (FCC, UL, CE, ma isi).
E leai se Laisene e tu'uina atu i lalo o so'o se aia tatau pateni po'o isi mea tau le atamai po'o le a lava. LT C e leai se noataga mo talosaga fesoasoani, tagata faatau oloa mamanu, polokalama faakomepiuta, po'o le solia o pateni po'o so'o se isi lava aia tatau tau le atamai o so'o se ituaiga. LT C i le taimi nei o loʻo tautuaina le tele o tagata faʻatau mo oloa i le salafa o le lalolagi, ma o le mea lea o lenei fefaʻatauaiga e le faʻapitoa.
Fa'amolemole faitau le tusi lesona DEMO BOARD a'o le'i tagofia le oloa. O tagata o lo'o fa'aaogaina lenei oloa e tatau ona i ai a'oa'oga fa'aeletonika ma mata'ituina tulaga lelei fa'atinoga o falesu'esu'e. E faamalosia le mafaufau lelei.
O lenei fa'aaliga o lo'o iai fa'amatalaga taua mo le saogalemu e uiga i le vevela ma voltages. Mo nisi atugaluga saogalemu, fa'amolemole fa'afeso'ota'i se inisinia talosaga LT C.
