The Touch Sensor operates in two modes: mouse mode or trackball mode. In Touch

to operate like a Mouse. Uncheck Mouse Mode if you want to use trackball mode.

Use the Sound settings to change the volume for media or alarms or turn on or off 
the audible selections. Audible selection plays a sound every time you select items 
in the user system.

When you select Volume, a dialog appears and provides volume controls for media 
(such as music and videos) and alarms.

You can use Display settings to configure the projector brightness, and other screen 
settings. 

Brightness in Display settings affects the brightness of the projected image. When 
the MP220 is turned on for the first time, Brightness is set to Minimum. The image 
brightness increases by 30%, when you change Brightness from Minimum to 
Maximum. The noise from the cooling fans will increase when Brightness is set to 
Maximum.
