#Person1#: What can I do for you, Sir?
#Person2#: I'm Tom in room 508, and I want a wake-up call tomorrow morning.
#Person1#: At what time?
#Person2#: 6:15 am, please.
#Person1#: No problem, we have a computer wake-up service. Please dial 2 first and then the time. That is to say, dial 2 and then 0615.
#Person2#: I see. I should dial all the numbers 20615 in turn. Thank you. By the way, if I want to change my wake up time, what shall I do?
#Person1#: Just dial your new wake up time, the computer will record the new wake up time and delete the previous numbers automatically.
#Person2#: If I dial 20700, I will be waked up at 7:00 am, am I right?
#Person1#: Yes, quite right.
#Person2#: Thank you. Goodnight.
