A: Have you checked your smoke detectors recently? B: No, I wasn't even aware we had smoke detectors. A: All the apartments are equipped with them. It's an essential safety feature. B: How do you check if they're working? A: It's real easy. If you like, I could show you. B: That would be nice of you. A: Are you doing anything right now? B: No. It's my day off work. A: How about I come over and show you how to check them? B: Sounds good. Come inside. A: It's really easy to check them. Just grab one from the wall, and check the battery in the back. B: What does this light mean? A: If you see the light, that means it's functioning. B: So I don't need to replace the battery. Thank you so much.
