The Insignia that I have was given to me as a used gift. For this reason, it didn't come with a manual. However, now I keep getting an error ( Nod 15 ) after each time I try to listen to a CD (which does not work). If possible, could you guys upload either the manual, or just give me a possible solution? I've tried finding an answer for the problem, but can't seem to find any help, or the manual. Help is much appreciated. Thank you for your time.
