Go to the manufacturer's website, type in your model number, click on Customer Service, Service, Support, (something that looks like it might give you help or documentation for the player). Sometimes all it takes is for you to type the name and model number in the Search bar of your browser, followed by a comma, and the word "manual", to see if it's available online. If not, look on the maker's homepage for an address there or contact them by e-mail with your request.
