3.3.1. Keypad functions
The front panel keypad provides the following functions (going from left to right in the
figure below):
 Menu button. Pressing this brings up the OSD (On-Screen Display) menu. Once
in the OSD, this button is also used to select the highlighted OSD option. The
OSD is described in Chapter 7, Getting started and OSD operation.
 A valid video input signal must be present for the OSD menu to be displayed.
 Brightness up and down buttons. Pressing these buttons increases and
decreases the backlight brightness. There are 64 levels of brightness.
 These buttons control the actual brightness of the backlight (it does not do a
colour shift – which is how most LCD monitors work). The brightness setting
has a direct impact on power consumption. The lower the backlight
brightness, the lower the power consumption. Refer to section 5.5, Power
consumption, for power consumption figures.
 In OSD mode, these buttons are used to navigate through the menus, and
adjust values (up and down).
 Status Indicator LED. It indicates the following:
 When green, a valid video signal is being received.
 When amber and flashing quickly, no video input is present.
 When amber and flashing slowly, the PC has turned off video and placed the
monitor into low power mode.
 Power On/Off button. Press this button to turn the monitor on and off. Note that
when off, the monitor is still consuming power, but in a lower power state. To set
the monitor so that it consumes no power, you need to use the On/Off Control
signal in the Monitor Power and Signal Cable – refer to Chapter 4, Connector pin
assignments.
