To do a search:
1. Turn on the DVD
2. Press and hold Set, then press the Power button
3. Press the DVD button on the 302
4. Press and release the Channel + button, then press the Power button
5. Repeat Step 4 until the DVD turns off; it may take 100 tries.
6. When the correct code is found, press the ENT button to store the code. If your DVD doesn’t work properly with this code, repeat steps 1-4 to see if you can find a better code.

If you need the manual, go here, when it opens, click on save, then download it to your desktop. I really doubt a code search will help, but it is worth a try.
