SAVING CUSTOM EQ SETTINGS
1. If your walkman has the DIRECT SOURCE set to ON, turn it OFF, then go to the EQ/Tone control Page (I'm using a NW-WM1A)
2. Mess with your EQ to your liking, the one i did is an example as it may look extreme. Once done editing the EQ values click complete on the eq settings.
3. Tap the SETTINGS Menu (Toolbox icon) then Tap saved sound settings. You are in the Saved sound settings options.
4. Tap the Save Current settings Button and the WHERE TO SAVE pop-up appears, choose one setting to save at (tap)

5. If the dialog prompt that tells you to replace the current settings pops-up, click OK

6. Your settings are now saved To retrieve them just Tap the saved sound setting 1, 2 or 3 (where you saved your cusyom EQ and other presets) and tey will load. If a prompt to overwrite current settings pops up, click OK to LOAD your SAVED SETTINGS
