 You can use `Property` only at class level. This means the *declaration context* for a property must be a class, structure, module, or interface, and cannot be a source file, namespace, procedure, or block. For more information, see [Declaration Contexts and Default Access Levels](declaration-contexts-and-default-access-levels.md).
 
-By default, properties use public access. You can adjust a property's access level with an access modifier on the `Property` statement, and you can optionally adjust one of its property procedures to a more restrictive access level.
+By default, properties use public access. You can adjust a property's access level with an access modifier on the `Property` statement, and you can optionally adjust one of its property procedures to a more restrictive access level. For detailed examples of mixed access levels, see [How to: Declare a Property with Mixed Access Levels](../../programming-guide/language-features/procedures/how-to-declare-a-property-with-mixed-access-levels.md).
 
 Visual Basic passes a parameter to the `Set` procedure during property assignments. If you do not supply a parameter for `Set`, the integrated development environment (IDE) uses an implicit parameter named `value`. This parameter holds the value to be assigned to the property. You typically store this value in a private local variable and return it whenever the `Get` procedure is called.
