7.3.11.3.6 Ambient Light Sensor
TII-LCD is equipped with an Ambient Light Sensor which helps to
increase the life-time of the LCD display. The LCD is switched off after
LCD switch off time is expired. So, to activate the LCD again, cover the
Ambient Light Sensor by hand during day time and flash light on the
Ambient Light Sensor during night time.
Configure Ambient Light Sensor threshold with appropriate value to
switch on LCD when covering with hand or using flash light on the
Ambient light sensor. Ambient Light Sensor threshold value is used as
reference to switch on LCD. When covering the sensor with hand or
using flash light on the sensor, if Ambient light sensor channel value
does not exceed configured sensor threshold it will not switch on LCD.
So, recommended to configure Ambient Light Sensor threshold with
appropriate value.
