Power Button
Power on- pressing the Power button turns the unit on. The front panel LED is green.
Standby- if horizontal, vertical or video signals are missing for more than 5 seconds, the
unit goes to standby mode. The front panel LED is amber. In this mode, only the USB,
Touch screen, and MSR circuits are powered. When all of the video signals come back up,
the unit resumes the Power on state.
Power off- holding the Power button down for 3 seconds or more puts the unit in the Off
state. Only the power button circuitry is powered in this state.
Menu Button
The Menu button brings the OSD up on the screen. The menu displayed is the last menu that
was on the screen when either the OSD was exited or the last menu on the screen when the
OSD timed out.
Auto/Select Button
The Auto function is invoked when the Auto/Select button is pressed, and the OSD menu is
not on the screen. The Auto function monitors the input signal, calculates the video adjustment
parameters and automatically adjusts the timing of the LCD to display the incoming video
properly. The Select function is active when the OSD is displayed on the screen. The (+) and (-
) buttons are used to navigate within each menu. When the desired function is reached, press
the Select button to choose that function and to advance the menu for that function.
(+) and (-) Buttons
The (+) and (-) buttons are used to navigate within menus and to modify selected control
values.
