I just picked up Senetinel Prime's leader class toy a few days ago. I'm assuming he's in display mode, since he only says one line of dialog right now, that being "I am Sentinel Prime". I couldn't see anything on the box or instructions that indicates how to take him out of display mode (if that's even the case. I only see one other button which makes his sirens go off.) With a lot of toys, holding the button down takes them out of display mode, or there's a switch. Anyone able to help out? I love how the siren makes him sound like he's whooping for great joy. Edit: It just occurred to me that, if he does have a switch, it'll likely be under the battery compartment. I'll look.
