High Temperature Warning
m40L/m46L Installation Guide 69
2 Set the
AMBIENT THRESHOLD
to an ambient light level at which the backlight
changes intensity. If the current
AMBIENT LIGHT
(shown on the bottom line) drops
below the threshold, the backlight dims; if it rises above the threshold, the
backlight brightens.
Note: Ambient light is a relative value, and is pertinent only to the m40L/m46L. It is not an
absolute value. You may get different ambient light values with a handheld light meter.
Note: The m40L/m46L has a nominal time delay of three minutes before it changes light
levels. This time delay prevents flickering if the ambient light level is near the ambient
threshold.
High Temperature Warning
The m40L/m46L has a feature that allows the display to recognize when it is too hot
and to automatically reduce the backlight intensity in an effort to cool itself down.
When this occurs, the display will show a warning message on the
BACKLIGHT
CONTROL
menu to let you know the display is not as bright as you want it to be. This
message includes the temperature and the backlight intensity the display is actually
using. See "Normal Use Thermal Guidelines" on page 5 for more information about
temperature guidelines.
