Volume
This is a volume bar that controls how loud the messages are read. Note: Please edit this setting before you drive. You cannot change the read volume mid-message with this option, or with the volume controls on your BlackBerry our Bluetooth device. To change the volume, click on the volume bar, select “Change Option” and use the roller wheel to turn the volume up or down. You can also hover over the volume bar and press and hold the Alt key and use the roller wheel to turn the volume up or down.
