5.3.4 UPDATE VIA SD CARD
Update with an SD card, which is the conventional method, is available if you write the
package firmware to the SD card.

If an error code is displayed, refer to Error Screens During Updating (page 5-9).
1. Create a new folder in the SD card, and then name it "package".
2. Copy the package firmware (xxxxxxxx.pkg) to this folder.

If you copy the package firmware into the conventional "romdata" folder, the update
will not work.

Only one version of the package firmware should be copied into the folder. If you
copy multiple versions of package firmware to the SD card, the machine will select
only one version of the firmware randomly.
3. Turn OFF the main power.
4. Insert the SD card which contains the package into the SD Card Slot 2 (lower).
5. Turn ON the main power, and then touch [Update].
