About 3 months ago I bought a new clock radio. Last night, I found that I needed to use the alarm for the first time. So I looked at all the buttons, took a wild guess as to how to set the alarm, and managed to change the correct time to the wrong time. But failed to set the alarm. So I searched the web and found a copy of the user manual. After following the instructions, I successfully set the alarm so that it would ring at 5:30am on every weekend morning for the rest of my life.
