How do you answer calls from Otis on Dead Rising

When someone calls you an icon that looks like a walkie talkie will appear. If you look closely it will tell you to press a certain button on the arrow pad. Press that button and a box will appear showing what evryone is saying. Be careful answering will make you vulnerable to attack by zombies.
