 ## Methods
 
-### Set volume level
-
-```python
-class MySirenEntity(SirenEntity):
-    # Implement one of these methods.
-
-    def set_volume_level(self, volume_level: float):
-        """Set new volume level."""
-
-    async def async_set_volume_level(self, volume_level: float):
-        """Set new volume level."""
-```
-
-### Set active tone
-
-This should only be implemented if the tone can be changed.
-
-```python
-class MySirenEntity(SirenEntity):
-    # Implement one of these methods.
-
-    def set_active_tone(self, tone: str):
-        """Set new active tone."""
-
-    async def async_set_active_tone(self, tone: str):
-        """Set new active tone."""
-```
-
 ### Turn on
 
 ```python
