You can check the TOP model name in two places:
First, it is printed on the label on the back of the product.
Second, after powering on the product and entering the menu screen, the model name is displayed at the bottom left corner.
For instructions on how to access the menu screen, please refer to post #7 in the [Video Manual] section.

 

To change the model name in the TOP Design Studio software:

Go to the [Project] > [Properties] menu at the top.

The [Project Options] screen will appear.

Click the first button at the top, [Change HMI], to open the [Select HMI] screen.

In the model selection area, first choose the series, then select the exact TOP model from the list below.

Click the [OK] button at the bottom to complete the change.

Transfer the project to the TOP device (Full Build & Transfer, F9) to apply and confirm the changes.
