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 has two options: automatic and manual. In 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 in the area of the m70L determine
the image brightness. This is useful when the m70L is in a location that sometimes
has daylight, which can vary.
When there is less ambient light, the screen can be darker and still be easily read.
When there is more light, the screen must be brighter to see it clearly.
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.
