Go to File > Advanced > System information to check on your current version number. The update you will download depends on your current display version number.
Perform the Update
- Current display version is 4.5.5 or later
- Current display version is 4.5.4 or earlier
After you get your system up to the 4.7.5 version, you can then download the 4.8.8 version and be up to date.
Do not unzip or modify the file in anyway.
Copy this file to the top directory on your USB drive
Place the USB drive into the touchscreen and follow the on-screen instructions by pressing the “Update System” button.
If the update file isn’t recognized
Sometimes the display won’t respond with an option to update the system when the USB is inserted to update. If you have Winzip installed, this may be interfering with the update file when it is downloaded.
If possible, try downloading the update on a computer on which Winzip isn’t installed. you could also uninstall Winzip temporarily and then re-install it after the update process is finished.
