Bayan kunna cikin yanayin atomatik, zaku sami kusan tashoshi 20 a cikin babban ma’ana. Idan kawai 10 cikin 20 aka samu, yi amfani da binciken hannu.

Saitin hannu

Saitin hannu ya ƙunshi abubuwa masu zuwa:

6. Bude “Saitunan atomatik”. Tushen siginar – “Cable”, nau’in tashoshi – “Digital”.
7. Zaɓi nau’in tashoshi bisa ga ra’ayinku – ko dai kawai “Digital” ko “Digital + analog”.
8. Saita yanayin bincike zuwa hanyar sadarwa.
9. Danna maɓallin “Search”.

Bayan bincike ta atomatik, zaku sami duk tashoshi na dijital da ke cikin hanyar sadarwar kebul, amma kawai kuna iya kallon waɗanda ke cikin kunshin ku.

Shirin yana kafa tashoshi da kansa. Bayan kammala, ba kwa buƙatar yin wani abu dabam. Akwai dalilai da yawa da ya sa tashoshi na dijital suka daina watsa shirye-shirye kuma babu siginar talabijin na dijital, amma kusan dukkanin su ana iya magance su da kanku. Babban abu shine yanke shawarar abin da ya faru daidai. Babu matsaloli tare da saitin na gaba ko dai, tunda duk saitunan suna kama da juna, kuma zaku iya samun mahimman bayanan ko dai daga mai badawa ko a cikin umarnin TV.
