7. SYSTEM CONTROLS
The ON-OFF control button is used not only to turn on and off
the device, but to activate the MENU as well. One short press on
this button activates the screen menu that controls brightness and
contrast of the screen. An extended press of this button in the
main mode turns the device off. The arrow buttons control zoom
and image presentation scheme in the main mode and change the
brightness and contrast in the menu mode. The table below
describes the functionality of each control button.
