If you receive a "Check Destination Pad" message in the SPD-SX while attempting to import a file, this means that there is a file already assigned to a pad in that particular Kit. Before importing, the pad must be "Unassigned." Here's how to unassign a pad in the SPD-SX:
** If you're using the Wave Manager software, disconnect the SPD-SX from the computer.
1. Choose the Kit that you're trying to import the file to.
2. Press MENU.
3. Cursor to "PAD," and then press ENTER.
4. Hit the pad that you want to import to (this selects the pad).
5. Press the (-) button to set the pad to "NO ASSIGN."
6. Repeat Steps 4 and 5 for any other pads if needed.
7. Press EXIT when you're finished.
You can now import a file to the desired pad(s) in the Kit.
