Personalizing Your Phone
Changing Volume Levels
You can change the following volume levels:
• Ringer (alerting tone)

You must be using the feature to change the volume level. For example, if you want to change

While using the feature, press (Up) to increase the volume or press (Down) to
decrease the volume. The volume level is automatically saved.
