I bought my radio/CD player 3 years ago.  Reception is terrible, but I bought it for the CD player.  I use the CD player every day and it has never given me trouble.  Yesterday a loud alarm went off when the unit was off and no one was in the room.  I unplugged it and waited a while, plugged it back in and the alarm was silent.  I have no idea why an alarm would be in the radio or what it was trying to tell me.
