Okay, check this out. My child press the stop button. Guess what? Abrupt stop, then complete silence, and total darkness! Nuts. Completely dead. 10 minutes, 5 holding down the alarm button, finally voice contact. Was close, so I opened up the door and was able to get me and my 2 kids out. This was a real bad situation I'm telling you. 1/4 or less battery on my cel. I could at least use that as a light source to calm my kids down. Hope no nightmares tonight!
