This message is displayed when you try to recall or save a pattern while no USB flash drive is loaded.

Check the following possible problems.

• Make sure that the USB flash drive is completely inserted into the USB port on the machine.
  If the USB flash drive is inserted, remove the USB flash drive from the USB port and reinsert it.
• It may take a little time until the machine recognizes the USB flash drive. Wait a few seconds, and try again.

   

If the problem persists, use another USB flash drive.
