In the end its always a pain when dealing with something likes this , as for myself , 50% of the times I type instead of talking , and I would not stop to type out a C4 when there are less than 15 seconds of it , I would run my as off .

it also depends if someone else called it out , say "Player X says in voice / types , that there is a C4 near the Tester "
"Player Y 20 seconds later walks past that C4 " He doesn't need to announce it as its already being called out .

My opinion
