Dongosolo la pansi ndi njira yotsutsana ndi kuba yomwe imakwiriridwa pansi ndipo sangathe kuwonedwa ndi makasitomala.Kuphatikiza apo, makina obisika apansi ndi mtundu wa AM anti-kuba system, ndipo ma frequency omwe amagwiritsidwa ntchito ndi 58KHz.Kuonjezera apo, dongosolo la pansi ndi limodzi mwa ntchito zodziwika bwino mu dongosolo la EAS, ndi chiwerengero chapamwamba chodziwika ndi ntchito yokhazikika.

Ubwino wa dongosolo la pansi:

1. Mlingo wodziwikiratu ndi zotsutsana ndi zosokoneza ndizolimba kuposa zida wamba za AM, ndipo ntchitoyi ndi yabwino kwambiri.Chida chobisika pansi sichikhala ndi vuto ndi chizindikiro chachitetezo, ndipo kuchuluka kwake komwe kumawonekera kumatha kufika kupitilira 99%.

2. Kukwiriridwa pansi kumabisika pansi, ndipo makasitomala sangawone pakhomo.Mashopu ena sayembekezera kuti makasitomala awone tinyanga zoyimirira zotsutsana ndi kuba chifukwa cha kapangidwe ka malo ogulitsira komanso malo apamwamba azinthu, ndipo vutoli litha kutha pokwirira pansi.

3. Dongosolo la pansi limapangidwa ndi magawo awiri, mbuye ndi koyilo.Mbuyeyo amaikidwa padenga, ndipo koyiloyo imakwiriridwa pansi;chizindikirocho chikadutsa, koyiloyo imazindikira ndikutumiza kwa mbuye, mbuyeyo amakhala alamu.

4. Kugwedezeka kotsutsana ndi kuba kumakhala kolimba.Akuba wamba adzawona kuti palibe mlongoti wa EAS womwe umayikidwa pakhomo la sitolo, ndipo chizindikiro chotsutsana ndi kuba chimabisika, iwo molimba mtima adzalowa m'sitolo kuti akabe zinthu, koma ngati sitolo ikuyikidwa ndi chipangizo chapansi, wakuba adzawululidwa pakhomo, pansi pa nthaka adzalira alamu, ndiyeno chitetezo chidzaletsa wakubayo.Mtundu wosawoneka wotsutsa kuba umadabwitsa kwambiri mbala, komanso umalola anthu ena omwe ali ndi cholinga choba kuti asiye kuba.
