Zogulitsa zimasinthidwa mosinthana pakati pa chifunga chamchere ndi chinyezi, ndikuwunika kusintha kwamagetsi ndi makina azinthu zamakina onse.
Kodi zowunikira za Liper zimayesedwanso kutsitsi?
Yankho ndi lakuti Inde! Zida zachitsulo za Liper zopangira nyali ndi zowunikira zimapangidwa molingana ndi miyezo yapadziko lonse lapansi. Kutengera muyeso wa IEC60068-2-52, amayezetsa dzimbiri mwachangu ndikuyesa kutsitsi mosalekeza kwa maola 12 (pazitsulo zachitsulo). Pambuyo pakuyesa, zida zathu zachitsulo siziyenera kuwonetsa zisonyezo za okosijeni kapena dzimbiri. Pokhapokha pomwe zowunikira za Liper zitha kuyesedwa ndikuyeneretsedwa.
Tikukhulupirira kuti nkhaniyi ithandiza makasitomala athu kumvetsetsa kufunikira koyesa kupopera mchere. Posankha zinthu zounikira, ndikofunikira kusankha zinthu zapamwamba kwambiri. Ku Liper, zogulitsa zathu zimayesedwa kwambiri, kuphatikiza kuyezetsa kopopera mchere, kuyezetsa moyo wautali, kuyesa kosalowa madzi, ndikuphatikiza mayeso am'mbali, ndi zina zambiri.
Macheke abwino awa amawonetsetsa kuti makasitomala a Liper amalandira zowunikira zapamwamba kwambiri, zodalirika, motero zimakulitsa moyo wamakasitomala komanso kukhutira kwathunthu.
Monga katswiri wopanga zowunikira, Liper ndiwosamala kwambiri pakusankha zinthu, kukulolani kuti musankhe ndikugwiritsa ntchito zinthu zathu molimba mtima.
