FCC STATEMENT: O lenei masini e tausisia le vaega 15 o Tulafono FCC. O le fa'agaioiga e fa'atatau i aiaiga nei e lua: (1) e le mafai e lenei masini ona fa'alavelave fa'alavelave, ma (2) e tatau i lenei masini ona talia so'o se fa'alavelave e maua e aofia ai fa'alavelave e ono mafua ai le fa'agaioiga le mana'omia. So'o se suiga po'o ni suiga e le'i fa'amaonia manino e le itu e nafa ma le usita'ia e mafai ona fa'aleaogaina le pule a le tagata fa'aoga e fa'agaioi ai masini. FAAMANATU: O mea faigaluega nei ua uma ona fa'ata'ita'iina ma maua e fa'amalieina tapula'a mo se masini numera Vasega B, e tusa ai ma le Vaega 15 o Tulafono FCC. O nei tapula'a ua mamanuina ina ia maua ai se puipuiga talafeagai mai fa'alavelave fa'alavelave i totonu o se fale fa'apipi'i. O mea faigaluega nei e gaosia, fa'aoga ma mafai ona fa'avelaina le malosi ole alaleo ma, a le fa'apipi'iina ma fa'aogaina e tusa ai ma fa'atonuga, e ono fa'alavelave fa'alavelave i feso'ota'iga leitio. Ae ui i lea, e leai se faʻamaoniga o le a le tupu se faʻalavelave i se faʻapipiʻi faapitoa. Afai o nei meafaigaluega e mafua ai le faʻalavelave faʻaleagaina i le leitio poʻo le televise, lea e mafai ona faʻamautinoa e ala i le tape ma ola o meafaigaluega, e faʻamalosia le tagata faʻaoga e taumafai e faʻasaʻo le faʻalavelave e ala i se tasi pe sili atu o faiga nei: - Toe faʻaleleia pe toe faʻafeiloaʻi le antenna. fa'alavelaveina e se tasi pe sili atu o faiga nei: — Toe fa'atonu pe toe fa'anofo le antenna e maua ai. - Faʻateleina le vavaeeseina i le va o meafaigaluega ma le faʻamalo. — Fa'afeso'ota'i le masini i totonu o se so'o i luga o se ta'amilosaga e ese mai le mea e fa'afeso'ota'i ai le fa'avevela. — Fa'afeso'ota'i le tagata fa'atau po'o se tekinisia o leitio/TV mo se fesoasoani. O nei meafaigaluega e ogatasi ma tapula'a fa'aola fa'avevela a le FCC ua fa'atulaga mo se si'osi'omaga le pulea. O nei mea faigaluega e tatau ona fa'apipi'i ma fa'agaoioia ile la'ititi ole mamao ole 20cm i le va ole radiator ma lou tino.
Suiga po'o suiga e le'i fa'amaonia manino e le itu e nafa ma le usita'ia e mafai ona fa'aleaogaina le pule a le tagata fa'aoga e fa'agaioi ai masini. O fa'agaioiga i le fa'aili 5.15-5.35GHz e fa'atapula'a na'o le fa'aoga i totonu.
