Question: I want to clear my recorder of all loaded files. How do I format the recorder?

The recorder and memory card should be formatted only by using the internal FORMAT function found in the recorder’s Menu. Using a computer to format a card will render the card unusable in the DS-4000. The card will have to be formatted in the recorder to restore functionality.

To format the card in the DS-4000, do the following:

  1. Press and hold the MENU button for one second or longer.
  2. Press the FF or REW button until SUB MENU is displayed on the LCD.
  3. Press MENU to enter the submenu.
  4. Press the FF or REW button until FORMAT flashes on the display.
  5. Press the MENU button to select FORMAT.
  6. Press the FF or REW button to highlight the START option.
  7. Press MENU to select FORMAT. The recorder will display a message stating that all data on the card will be cleared, and then it will prompt for confirmation to continue the FORMAT operation.
  8. Press the FF or REW button to highlight START a second time.
  9. Press the MENU button to confirm START selection and format the card.
