Setting Backlight Timer
The backlight illuminates the display when you receive or make calls or use the
phone in poor lighting conditions. You can set the amount of time that the
backlight stays on to 5, 10, 20, or 30 seconds, or set it to stay on continuously or
stay off at all times.
NOTE: Setting the backlight to stay on continuously will decrease the
amount of time you can use the phone before recharging the
battery.
Setting Photo Sensor
To conserve battery power, the photosensor will disable the backlight when you
are in good lighting conditions. To force the backlight to come on every time a
key is pressed, turn the photosensor off.
NOTE: Turning the Photosensor to OFF will force the backlight to come
on every time a key is pressed and will drain your battery power.
