The instruction manual will not help you, because it doesn't address this problem head on.  You're having this problem because the time changed, and the clock has an automatic setting.    As long as the batteries are in the clock and it's plugged up, it automatically computes the time. I just discovered the solution.  Unplug the clock, take out the batteries and WAIT about an hour.  Plug it back up, and the time will flash, allowing you to change the time.  You do this with the button on the top back which says wake up 1 and wake up 2.  Push that button all the way to the right to the setting that looks like a little clock, then press the forward button on the top of the clock to set the correct time.  Then put your batteries in and you're good to go!  (til the time changes again:)  Good luck!

Here's a link to a site that claims to have the manual.

In order to download you need to register. It's free. I haven't used this site but I do download from a few other tech sites that require registration. It's never led to any problems (spam emails, etc.) but you should scan anything you download from any site for viruses just to be safe.

Look at the display. Look for a number 1 or a number 2 to determine which alarm is on. If you see a number 1, push the 1 button on the top right side of the alarm clock until the number light goes off (1 or 2 times, depending on whether it is set to beep or radio alarm). When the number is not lit up, the alarm is off.

There are three buttons under the heading "Dual Wake", WK1, Cancel, WK2. The WK buttons refer to the two wake time settings you can have. Press Cancel and then WKx. That will turn off the alarm. If you press WKx more than once, it will cycle through small symbols on the bottom of the screen with the number x in front of them. First symbol means it will have a sound alarm for alarm x, second symbol means it will have a radio alarm and the third symbol means it will play the CD to alarm. You set the time for alarm with the slide switch at the back of the unit, selecting WK1 for alarm 1 and WK2 for alarm 2. You can have both alarms active at once, or either one singly.
