Backlight Control
72 m40L/m46L Installation & Configuration Guide
The backlight is optimized for the LCD operation. For normal operating conditions,
the backlight can be adjusted for maximum brightness if desired. If you are operating
at higher altitudes up to 2000 meters, it is recommended that you run the backlight
at a reduced intensity. Running at maximum intensity at high altitudes can affect the
lifetime expectancy.
Note: The look of the BACKLIGHT CONTROL menu depends on whether it is in manual or
auto mode.
Auto Backlight Control
1 Set the BACKLIGHT CONTROL MODE to AUTO.
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.
