1. Turn OFF the main power, and then remove the power plug and cables that are connected.
  2. Open the rear upper cover [A].
  3. IM 550F/600F: Insert a flathead screwdriver into [A] to release the hook on the inside of the controller cover [B].

  4. Release the hook by opening the right side of the cover, and then remove the cover [A] by rotating it in the direction of the blue arrow.

    • Be careful not to damage the hooks on the inside of the controller cover when you remove or install the controller cover.

  5. Insert the DataOverwriteSecurity Unit Type M19 SD card in SD Card Slot 1 [A] (upper slot).
  6. Reattach the controller cover.

  7. Insert the power cord into the outlet and turn ON the main power.

  8. Enter the SP mode.
  9. Do this step only if you are installing the option on a machine that is already in use (not a new machine):
    • If the customer wishes to continue using the same hard disk, execute all three SP modes below.
      • SP5-801-014 (Clear DCS Setting)
      • SP5-832-001 (HDD Formatting (ALL))
      • SP5-832-002 (HDD Formatting (IMH))
    • If the customer wishes to replace the hard disk with a new one, execute SP5-801-014 only.

    • If the customer continues using the same hard disk, the overwriting of the data stored on the disk before the option is installed cannot be guaranteed. It is highly recommended to replace the hard disk with a new one.

  10. Set SP5-836-001 (Capture Function (0:Off 1:On)) to a value of 0 (Disable).
  11. Execute SP5-878-001 (Option Setup: Data Overwrite Security).
    If the installation fails, "Installation failed" is displayed when this SP is executed.
  12. Print out the System Settings List and make sure that the option was installed successfully.
  13. Reconnect the network cable.
  14. Execute SP5-990-005 (SP print mode Diagnostic Report).

    • "ROM Number / Firmware Version" – "HDD Format Option"
    • "Loading Program"
