1.4.1 ADJUSTING THE LCD BACKLIGHT
The backlight of screen helps ease reading in dim environments. It can be turned on/off
by pressing the [
] key located at the bottom center of the keypad. Also backlight level
can be adjusted through programming or via System Menu. Refer to
3.2.3 Backlight.
Using backlight while on battery power will substantially reduce battery power. We
suggest that you switch off the backlight while there’s no need to read the screen or have
it set to be automatically turned off when it has been idle for a certain period of time.
