OPERATION OF THE AREARAE
2-22
2.7 Backlight
The LCD is equipped with a backlight to assist reading under
poor lighting conditions. When the monitor is in Normal
Operation mode, the backlight may be manually turned on by
pressing and holding [N/-] for one second. Press [N/-] a second
time to turn off. If [N/-] is not pressed, the back light will
automatically turn off after preset time-out period (set by
ProRAE Suite) to save power. The back light automatically
activates during alarm conditions.
Note:
The LED backlight consumes a higher amount of energy
from the battery and shortens the operating time of the monitor
by 20% to 30%.
