Bokosilo limakhala ndi thupi ndi chivundikiro chomwe chimakhala ndi phula.Kukonzekera kwapakhoma kumaphatikizidwa m'bokosilo.
Chivundikirocho chimakhala ndi malo osiyanasiyana otsegulira, omwe amatha kusankhidwa malinga ndi kuchuluka kwa malo ogwira ntchito omwe alipo, komanso amaikidwa ndi chisindikizo kuti achepetse kulowa kwa madzi.
Ma grommets amaperekedwa kuti athe kupeza mawaya ogwetsa (2 x 2 pamawerengero ang'onoang'ono ndi 2 x 4 kwa awiriawiri 21 ndi pamwambapa).
Njira yotsekera bokosi imakwezedwa kudzera pa chingwe cha chingwe ndipo imakhala yothandiza potseka bokosi;kuti mutsegulenso bokosilo kiyi yapadera kapena screwdriver imafunika kutengera mtundu wa loko.
Chotsekeracho chimapangidwa padera kenako ndikumangirira mubokosilo.Mibuko imatha kupangidwa kuchokera pa mapeya 5 mpaka 30 mu mayunitsi a 5 ndipo potengera oyendetsa awiriawiri atha kuperekedwanso.
Malo oyambira pansi a gulu lililonse amalumikizidwa ndi magetsi ku chotchingira chingwe komanso potengera malo akunja.Chigawocho chimasindikizidwa ndi utomoni ndipo cholumikizira chingwecho chimasindikizidwa ndi machubu omwe amatha kutentha.
Izi zimagwiritsidwa ntchito poyimitsa zingwe zama netiweki amafoni achiwiri ku ma chingwe awiri a mizere yolembetsa.Njira yolumikizira ma module a STB imagwiritsidwa ntchito popanga maulumikizidwe ndipo imalola kuti awiriawiri azitetezedwa mosankhidwa ndi kugwiritsa ntchito ma module a plug-in motsutsana ndi overvoltages, overcurrents, kapena ma frequency osafunika.Kupereka kuthekera koyesa kutali ndi njira ina.
Mabokosi a mawonekedwe a UG/Aerial Networks
1.STB ndi gawo lodalirika kwambiri lolumikizana, lopangidwa kuti lizitha kupirira nyengo zonse zomwe zilipo.
Malo ogawa
2.Watertight mwa mapangidwe, imapereka ntchito yabwino kwambiri pazotsatira zotsatirazi:
Zida zoyimitsa makasitomala.
3.Kuphatikizika kwakukulu, miyeso yonse imalola kuti m'malo mwa njira yomwe ilipo yotetezedwa ndi yankho lodalirika kwambiri.
4.Palibe chida chapadera chofunikira, kokha ndi dalaivala wamba wa screw.
