I want to know how to say "to set a timer" as in "set a timer for 5 minutes (on your phone)".
If I search in Reta-Vortaro for "timer", it just says "nenio trovigxis".
Maybe I could say:
"agordi tempilon por soni post 5 minutoj"
But I have no idea how to say "timer". Tempilo seems completely wrong. Also, is the rest of this sentence correct?
