Kingtone Fa'asinomaga fa'alavaVHFAuala FilifiliaBi Directional Amplifier (BDA)o ni fofo taugofie ma fa'atuatuaina ua fuafuaina e fa'alautele ma fa'aleleia le vaega o lo'o aofia aiVHFfaiga fa'afeso'ota'i intercom.Channel Selective BDAs e mafai ai e le tagata faʻaoga ona faʻateleina naʻo mea e manaʻomia i itu uma e lua, uplink ma lalo.Ole filifiliga ole alavai e mafai ona fa'apolokalameina ile lotoifale ile RS 232 pe mamao ile Modem po'o le RJ45.
FAAMATALAGA
Fa'aaliga 1: O le malosi o le fa'aogaina o le system o se galuega o le numera o felauaiga na tutupu i luga o le faiga, o le maualuga o fa'ailoga o nei va'a i le
faiga fa'aleleia o fa'ailo, maua o PA's, ma le fa'aofiina e leiloa o fa'amama i totonu ole faiga fa'aoga lua.
Fa'aaliga 2: Fa'ailoga Pisa o le System o le aofa'iga o le fa'amalo NF ma le fa'amama gau a'o le'i o'o i le fa'amalo.O le faamama gau a toe faalagolago i
le lautele passband mo laina i luga, o le passband lautele mo laina lalo, ma le tape taofi i le va.
O le iai o le VHF Repeater BDA e maua ai le feso'ota'iga feso'ota'iga feso'ota'iga fa'atasi ai ma le maualuga o le aofa'i o tagata nofoia, talu ai e fa'alautele le fa'asalalauga i tua atu o le fa'asalalauga.O fa'aoga masani o lenei laina o ta'avale o tulaga i totonu e pei o alalaupapa, fale, alalaupapa, ma fa'aaliga i fafo e pei o malae ta'alo, nu'u i tua ma nofoaga mafiafia i le taulaga.Ona o se faiga lua o meafaigaluega, o lea e mafai ai ona e faasaoina le tau o le faaluaina o le fafaga.
