Before you start, check the system program version of your SY-1000.
- While holding down [ EXIT ] button, turn power ON.
Continue to hold down EXIT until the SY-1000 logo appears on the display.
- After a short while, the version information appears on the display.
If this shows the latest version (Version 1.20 or later), there's no need to update your SY-1000.
- After verifying the displayed version, turn off the power.
* Don't perform the update if the product is already up-to-date.
