Setting a Default Extent
Use the Default Extent button to return the map to its default extent. Initially, this is set to the extent of your territory.
You can modify the default extent by following these steps:
Zoom the map to the extent you wish to set as default
Right-click on the Default Extent button.
You will see a notification that the default extent has been saved.
Now, when you press the Default Extent button, the map will zoom to your custom extent.
To reset the default extent back to the full extent of your territory, repeat the steps above.
