The End Game [On Hold]

There were four holes like a football sized circle is divided into four each in the wall. Structure of holes at the front wall was a bit different comparetively to others. Marvin tried to apply some techniques at these holes but all in vain. He thanked god that he already jamed the burgular alarm.
Amber : What should we do now?!
Marvin : There must be a way to solve this puzzle.
Amber turned on the torch of her cell phone and started to observe it closely and then suddenly jumped.
"O Look!! there's something written in between each hole"
Marvin bent onto the holes and read four words
in four holes.

Fire _ Flame _ Flute_ Fun

Amber : It looks interesting.
There was a small bead sized button at the centre of the circle.
Marvin pressed it.
