There is no manual. This unit is considered vintage from a time before the Internet and its repository of manuals.

These that the closest.

Kylie, if there is a CD tray press the eject button and put CD in tray, push tray in easy to load. If no CD tray insert CD into CD slot and push gently to load. Some have a lid on top that you simply open with your finger then load CD. Check the attached links,instruction and guides, Good luck

Problems With My GE General Electric 7 4901A CD Player AM FM Clock Radio

There are 2 common mistakes with radio alarm clocks. 1) You have AM/PM backwards either on the actual time or alarm time 2) The volume is mistakenly set all the way down

When you set the alarm, turn the volume button on the front counter-clockwise (volume down) until it clicks. Darth will then wake you with one of three extremely LOUD, over-modulated soundbites or the electronic "beep-beep-beep" alarm . You can select the different soundbites/alarm with the "SELE-AL" button on the back. The only problem is, you can't tell which one you've selected until the alarm goes off. Cheap design.

sorry, I can't shed much light on this problem, but it appears to have been fixed. We played around with setting the time, although it didn't need fixing and with the timer.

Unplug the thing from the outlet and that will surely stop it.  Grab you a hammer and apply force to the unit multiple times and that will surely stop it.  Use the kitchen sink sprayer and hose the thing down and that will surely stop it.

push the time button then set the time then push the time button a second time.

If you are using a pirated cd or self compiled cd, chances they don't play. try the original cds

Press SET to enter time setting mode. Use the TRACK/SEARCH/TUNE buttons to select the correct time. Press SET to save clock time.

Reboot the machine, including taking out the batteries. Don't know what causes it, but that's the only way mine stopped, and I'm never touching the Timer button again, because I think that's what got the problem started.
