Creating an SD Card for Updating

1. Download the update modules from Firmware Download Center. As one of the model
modules, "Java VM v12 UpdateTool" is available for download. (The version differs
depending on the model.)
2. Unzip the downloaded file. Copy the whole "sdk" folder to the root of the SD card directly
below.
• When unzipping the downloaded file, two subfolders ("update" and "sdk") exist in the "sdk"
folder. Rather than just copying the subfolder "sdk", copy the whole folder "sdk".

Updating Procedure

• SD card can be inserted with the machine power off.
• During the updating process, do not turn off the power.
• If you turn off the power during the updating, the machine performance is not guaranteed. (There is
a possibility that an SC and boot failure occurs.)
• If you accidentally turn off the power during the updating, retry the updating procedure from the
beginning. (If the update fails again, you will need to replace the controller board.)

priority application is set to the ESA application, switch to the home application. ([User
Tools]- [Screen Features]- [Screen Device Settings]- [Function Priority]- [Home])

Feature Settings] – [Extended Feature Settings] – [Administrator Tools] – [Heap/Stack
Size Settings])
The Heap size setting is changed to the initial setting when updating.
3. Turn OFF the main power.
4. Insert the SD card for update into the service slot.
5. Turn ON the main power.

minutes)
