1.4.1 ADJUSTING THE BACKLIGHT
The backlight of screen and keypad makes it easier to operate the mobile computer in
dim environments. By pressing the following key combinations, LCD backlight can be
turned on/off and the brightness can be adjusted. Keep pressing the key combination
until the brightness or contrast decreases or increases to a desired level. Alternatively
the brightness and contrast are controllable through programming or via System Menu.
Refer to
3.2.2 Backlight and 3.2.13 Contrast.
Note: Using backlight on battery power will substantially reduce battery power. We
suggest that you dim the backlight while working in a well-lit area or set it to
automatic power off when the computer isn’t actively used.
Use the following key combinations to adjust the backlight for the mobile computer’s LCD
and keypad, and also the contrast for the LCD. Combine the keys by pressing the [fn]
key first and then pressing the second key.
