Uhlelo lokusika oluhlakaniphile lwe-PK4 luyithuluzi lokusika elizenzakalelayo ledijithali. Uhlelo lucubungula ihluzo ze-vector futhi liziguqule zibe amathrekhi okusika, bese uhlelo lokulawula ukunyakaza lushayela ikhanda lokusika ukuze liqedele ukusika. Imishini ifakwe amathuluzi ahlukahlukene wokusika, ukuze ikwazi ukuqedela izinhlelo zokusebenza ezihlukahlukene zokubhala amagama, ukuklama, nokusika ezintweni ezahlukene. Ukuphakela okuzenzakalelayo okufanayo, idivayisi eyamukelayo kanye nedivayisi yekhamera kubona ukusika okuqhubekayo kwezinto eziphrintiwe. Ilungele ukwenziwa kwesampula kanye nokukhiqizwa okwenziwe ngokwezifiso okwesikhathi esifushane ezimbonini zezimpawu, zokuphrinta nezokupakisha. Kuyimpahla ehlakaniphile engabizi kakhulu ehlangabezana nakho konke ukucubungula kwakho kokudala.
