Keypad Special Functions
The keypad special functions are color coded on the keypads. For example, on the 53-key keypad, the
display backlight icon is blue indicating that the blue function key must be selected first to access the
display backlight. On the 43-key keypad, the display backlight icon is white indicating that the display
backlight is the default value for that key.
Use of display and keypad backlighting can significantly reduce battery life.
Mobile computers with color screens do not have contrast settings.
