IPA: //ʌnˈprəʊɡræmd//
KK: /ʌnˈprɒɡræmd/
Not set up or arranged in a specific way; lacking a predetermined plan or instructions.
The device remained unprogrammed until the user decided to set it up.
Unprogrammed → It is formed from "un-" (meaning not) and "programmed" (from the Greek "programma", meaning a written public notice or a plan). The word "unprogrammed" means not planned or not set in a program.
Think of 'not' ('un-') being applied to something that is 'planned' ('programma') — that's why unprogrammed means something that is not planned.
