Jensen SC-570 Universal Remote

Try the auto code scan:

The Auto Code Scan feature allows you to set up your components without having to enter in code numbers. The Jensen will do the work for you! (It may take a few minutes to find your code using this method.)
Turn on the component that you want to set up.
Hold the component key down until the light comes on. The green light should come on after approximately 3 seconds.
Release the component key.
If you are programming the DVD or CD device press the "action" key. The red indicator light will come on.
Press "0" - "9" The green light will blink as codes are sent.
As soon as the remote turns your component off, press the "action" key. (You have 1 second in which to press the "action" key to save the code.) The component key lights will blink with an upward motion when a code has been successfully entered. The component is now programmed. To find that code, proceed to Code Readback.
If none of the codes turn your component off, return to step 2 and start over.
