1.4.1 ADJUSTING THE BACKLIGHT

The backlight of screen and keypad helps ease reading under dim environments. It can
be turned on and adjusted decreasingly or increasingly by the following key
combinations. Keep pressing the key combination until the luminosity or contrast is
decreased or increased to a desired level. Alternatively, the luminosity and contrast can
be configured through programming or via System Menu. Refer to
3.2.3 Contrast.
Note: Using backlight while on battery power will substantially reduce battery power. We
suggest that you dim the backlight while working in a well-lit area or have it set to
be automatically turned off when not in use.
