Display Backlight
A display backlighting feature is available and depending upon programming, will operate in one
of three ways:
1. Backlighting Off. This is the most efficient way to operate the computer with
battery power.
2. Backlighting On For A Short Time. This will provide display backlighting for a
predetermined amount of time. Use of this feature will result in reduced battery life.
3. Backlighting On Whenever The Unit Is On. This provides full time
backlighting to the display whenever the unit is turned on. It greatly reduces the
expected battery life.
Display Backlight Timer
When the Display Backlight Timer expires the display backlight is turned off. The default value
for this parameter is 3 seconds. The value can be adjusted using the BIOS Setup. Refer to the
“MX3 Reference Guide”.
Any of the following will wake the display and display backlight:
• Display update by host or currently running application on the MX3
• Any key on the keypad
• Pen-touch on a touch screen display
When the display wakes up, the Display Backlight Timer will begin the countdown again. When
any of the above events occur prior to the timer expiring, the timer starts the countdown again.
The ability of touch screen activation to wake up the MX3 is configurable in BIOS Setup. Refer to
the “MX3 Reference Guide” for details.
