[speaker001:] Maintenance Department. May I come in?
[speaker002:] Come in, please.
[speaker001:] Did you call us?
[speaker002:] Yes. The television is not working properly.
[speaker001:] What's the problem?
[speaker002:] The remote control doesn't work. I turned on the television, but I can't change the channel.
[speaker001:] Let me have a look. I think the batteries should be changed. Let me replace them with new ones. Now, it's working.
[speaker002:] That's great.
[speaker001:] Is there anything else I can do for you?
[speaker002:] No, thanks.
[speaker001:] If you have any problems, just call us.
[speaker002:] OK. Thank you.
