CATV me te Whakapāhoawhi a Whakaparere
Āhuahira
1. Ma te kaitohu whanui tino pai.
2. Ko te ahua o te hangarau-nui i roto i te CATV me te L-roopu amiorangi muka hono hua
3. Ka taea te tango i roto i te muka whatu me te 47~2600MHz amiorangi me Tohu mamati CATV mamati me te tairitenga.
4. Whakauru ngawari; He waatea ki te kaiwhakamahi te whakauru.
5. Whakauru mana mai i +0~-13dBm.
6. He pai te aukati i te pokanoa electromagnetic
7.High mahi engari iti te utu.

Raihana Kupu
Kua kapi te ZSR2600 Series Receiver i te kotahi TAU Whakatau Raihana, ka tiimata mai i te ra tuatahi o to hoko. Ka whakawhiwhia e maatau ki a ia tana kaihokohoko hangarau tautoko katoa. Mena kua pau te raihana, ka utua noa e te ratonga whakatika nga waahanga (mena ka hiahiatia). Mena me whakahoki mai he waahanga mo te ratonga, i mua i te whakahoki mai i te waahanga, tena koa kia mohio koe:
1. Ko nga tohu tohu kua whakapirihia ki runga i nga kaainga o te waahanga me pai te ahua.
2. Ko nga mea maama me te panui e whakaatu ana i te tauira tauira, tau rangatū me nga raru me tuku.
3. Tena koa kohikohia te waahanga ki tana ipu taketake. Mena kaore i te waatea te ipu taketake, tena koa kohikohia te waahanga kia 3 inihi rawa atu o nga mea e ngongo ana.
4. Nga waahanga kua hoki mai me utu nama me inihua. Kaore e manakohia te kohinga COD me te kohi waka.
PANUI: matou mahi kaore hei kawenga mo te kino i pa mai i te kohinga kino o nga wae kua hoki mai.
Ko te ahuatanga e whai ake nei kaore i hipokina e te raihana:
1. Kaore i pai te mahi na te mea i pohehe nga kaiwhakahaere.
2. Ko te tohu whaihua kua whakarerekehia, kua pakaru kua / kua tangohia ranei.
3. Te kino i tukuna e Force Majeure.
4. Ko te waahanga kua kore e whakaaetia kia whakarereketia kia / kia whakapaihia ranei.
5. Ko etahi atu raru i puta mai i nga he o nga kaiwhakahaere.
Rongoā Raru Noa
1. Te ka marama te hiko i muri i te hono atu o te hiko
Take:
(1) Kaore pea i te hono te hononga hiko
(2) Te he o te hiko
Rongoā:
(1) Tirohia te hononga
(2) Hurihia te mana whakauru
2. Te whatu IN Whero Whero
Take:
(1) Whakauru muka <-12dBm kaore ranei he Whakauru whatu
(2) He wewete te hononga muka
(3) Kua paru te hononga honohono
Rongoā:
(4) Tirohia te whakauru
(5) Tirohia te hononga
(6) Whakapai i te hononga muka
