I can only suggest that you go to this webpage
http://support.memorex.com/
and either contact support, or use ask a question form for pukka information (assuming I am correct in thinking that this model is manufactured and sold by Memorex)
Other than that, I can only suggest buying/asking a the seller a second hand machine that comes with a manual.
Manuals for Memorex portable CD players do exist, but not it seems for the MD6250CP, I don't how similar they are. Meorex support might be able to answer this too.

You'll need not just speakers but amplifier also. This one you can connect to linear output.

Please confirm model number
number of batteries in the battery bay 3,4 or 6

Will just buy a new one.

Thank you

use the player direct power from the net other wise you have to buy a adapter with the power out for your device can be used universel
look first up how manny voltage you need 6 or 9 or 12 volt if you now thad buy a adapter with at least 1 or 2 amp how more how solid they are

I had the same problem. One day my Mp3 started acting weird and said it was not recognizing the files and that i needed to re download them. Try plugging it up to your computer while its charging and hit the power off. Then reset your mp3 with the button at the bottom and it should recognize it.
