1. I-ALARM YE-VOLTAGE EPHANSI - Ingcindezi ephansi ikhuthaza isikhathi ngasinye lapho uvula umnyango ngekhadi, lapho i-voltage ingaphansi kuka-4.8V.Isixhumi esibonakalayo sangaphandle sokusekela ugesi: singavulwa izikhathi ezingaphezu kwe-100 kusukela ku-alamu yokuqala ye-voltage ephansi.
2. INDLELA YOKUVULA - Ukuze ikhadi le-IC livule umnyango, njengekhadi lesongo elimise okuka-W, ikhadi lesongo le-silicone, ikhadi lenkinobho, fanisa nesitayela sakho esikhethekile.Ikhadi elilodwa neliphindwe kabili, lingasetha ngokuzenzakalelayo umsebenzi wokuvula isikhathi esisodwa.Uhlobo lwebhande lokuzikhethela, uhlobo lwenkinobho nezinye izinhlobo zamakhadi, kulula ukulithwala, alikwazi ukungena emanzini, likwazi ukumelana nezinga lokushisa eliphezulu, nomsebenzi wokunqanda ukugqwala.
3. OKUPHEPHILE - Ulimi oluhlanzekile lwe-alloy lock, ukuthuthukiswa kwamandla okuphepha.Ngokunyakaza kwenhlanganisela yegiya, ukusebenza okuthembekile nokuphephile.
