The front panel of the control head includes a dot matrix display, controls for menu

Figure 7-1: Front Panel
The buttons on the front panel are backlit for operation in a low ambient light level such as
nighttime operation. Some buttons also flash to provide feedback of various operating
conditions.
In addition, the front panel contains a light-level sensor that samples ambient light levels
for automatic display and button backlight brightness adjustments. In other words, it
automatically brightens the display and backlights when higher external light levels exist
and it automatically dims the display and backlights during lower external light levels.
