Tohu Hua

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
