Setting Backlight
Idle Time
One way of saving the battery is to avoid those periods of time
during which the screen backlight is unnecessarily on.
As the receiver automatically counts the time during which
neither the keypad nor the touch screen is active, you can set
the receiver to turn off the backlight automatically after a
certain idle time.
• On the Home screen, tap successively , Settings, System
and Backlight.
• Choose the idle time before the backlight is turned off
(10 seconds, 30 seconds or 1 to 5 minutes). For
maximum power saving, you may clear the option that re-
activates the screen backlight on touching the screen or
pressing a key.
Different settings may be made for these two parameters
depending on the power source used (battery or external).
• Tap OK to save the settings.
