Kurogane followed the actions Fai's showed him, pushing the button with the device on the counter, then doing the same after raising it to his face. "And you think this is supposed to work?"

There was no sound from the blue item in Fai's hand, nor did the box Kurogane held feel like it was working. He remembered once when he'd seen someone taking a radio apart in the clinic and checked the toy for something similar. At the base he found the little latch and pulled a piece off, knowing the problem. "Batteries," he muttered. That's why these didn't work.
