You can also search for it on the internet.

There is not a way to change the ringtone volume for a specific person in a HTC Droid Eris but you can change the ringtone to a tone that is not loud for that person.
Get the manual, go to the contents and find "Ringtone". If not,go to the glossaryand try "Ringtone" also.

For EX-211 it seems that there is no way to set custom message alert tone (yet).
To change the notification ringtone on the Telstra Active Touch one must locate the messages button. Once in the messages, go to the menu, and then to select ringtone. There one will be able to change the ringtone to a different sound, or off completely.
It is simply Apple's default ringtone unless you change the default in Settings.
