Hi I have Samsung B2100 mobile phone. When I receive a message, the sound is so loud. Can you please tell me how to control the volume.

Menu/settings/phone profiles, select profile, then choose options at the low left corner of display. Here, you can adjust type of sounds you want and its loudness. Navigate to the right with your central button and here you are navigating downwards: 1. - message alert type chooser, 2. - message alert tone, 3. - message alert repetition, 4. - email alert type, 5. - email alert tone, email alert repetition, and finaly, 6. - alert tone volume. To enter into the submenu, first click direct the central button, and then choose the volume with left or right part of your central button. I am not a perfect english speaker, therefore I hope I was clear enough making this explanation.
