Backlight Control
Backlight control can automatically adjust the screen brightness as ambient light
conditions change.
Note: To extend the backlight life, it is recommended that you use the lowest backlight
brightness that makes sense for your application. This will reduce power consumption, heat
output and the chances of TIR from occurring. See "Recommended Usage" on page 6.
To open the BACKLIGHT CONTROL menu, go to MAIN MENU > ADVANCED OPTIONS >
BACKLIGHT SETTINGS .
Backlight control has two options: automatic and manual. In the manual mode, you
adjust the backlight brightness to suit ambient conditions that are not likely to
change.
In the automatic mode, you let the ambient light determine the image brightness.
This is useful when the m40L/m46L is in a location that sometimes has daylight,
which can vary.
When there is more light in the area of the m40L/m46L, the screen will have to be
brighter to see it clearly, and the backlight intensity will be 100%. When there is less
ambient light, the screen can be darker and still be easily read.
