Special Keyboard Buttons
There are special buttons (select models only) at the top of the keyboard. (Some models have some of these special buttons on the left side of the main keys.) These buttons operate a CD or DVD player, control speaker volume, connect you to the Internet, or provide quick access to specific functions.
Volume Control
The Volume knob increases speaker volume when turned clockwise, and decreases volume when turned anticlockwise. It can be turned indefinitely, even after maximum sound has been reached.
The Volume Up button increases volume, and the Volume Down
button decreases volume.
The Mute button turns speaker sound on and off.
