# Creating and Selecting Models

The system can store a large number of models, limited only by the capacity of the SD card. In practice, you'll have **more than enough space** for all the models you may need.

To create or select a model, go to the **Models** menu. From the home screen, press and hold the **cursor click** for a few seconds to open the main menu. Then, navigate using `←` and `→` until you reach the **Models** option, and click to enter.

### Creating a New Model

To create a new model use the `↑` and `↓`  cursor movements to select **New Model** option, then click to begin.

A dialog box will appear, allowing you to name the new model. The name can include up to **14 characters**, using: `a-z`, `0-9` and the hyphen character `-`.

* To select a character, use `↑` and `↓`.
* To move between character positions, use `←` and `→`.
* Repeat the process until the name is complete.
* When you're finished, click the cursor to confirm.

To cancel model creation, press and hold the cursor click for a few seconds until the dialog box disappears.

Once created, the new model is automatically set as the active model.

### Model Selection

To select a previously created model, use `↑` and `↓` to scroll through the list until you find the one you want. Once highlighted, click the cursor to select it. The icon next to the name will change, confirming it’s been selected.

You can now return to the home screen, where the name of the newly selected model will be displayed.
