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

lifetime expectancy.
Note:

This is the normal mode for applications where the displays will be on 24 hours a day.
This way, no one has to manually turn on the backlights after a power failure.
Caution: To prevent temporary image retention (TIR), is recommended that you do not
leave the Runco WindowWall on for 24 hours a day. To get the most out of your display, see
"Recommended Usage" on page 4.
If the displays normally have the backlights off for part of the day or night, do not
check this box. Otherwise a power failure at night would turn on the backlights.
