Optimizing Power Settings
Power Preferences enable you to adjust settings to maximize your device’s battery
performance.
1. Press Applications and select Prefs .
2. Select Power.
3. Set any of the following preferences:
䡲 Brightness: Sets the intensity of the screen and keyboard
backlights. Drag the slider or press Left and Right to
adjust the brightness level.
䡲 Auto-off after: Determines how long your screen stays on
during a period of inactivity. When there is no interaction
with the keyboard or screen for the specified time period,
your screen turns off automatically.
䡲 Backlight during calls: To preserve power during an active
call, you can set the screen backlight either to dim or turn off after a specified
amount of time. Turning off the backlight saves more power than dimming it. With
the backlight turned off, you can still see a faint image on the screen and use any of
the buttons on the screen. To return backlight brightness to normal, press any key or
tap the screen. Be careful; pressing Power/End hangs up an active call, and tapping
an onscreen button activates that command.
䡲 Beam Receive: Determines whether your Centro device is ready to receive
information over an infrared beam. If you leave this option off, you must return to this
screen to turn on this option the next time you want to receive beamed information.
4. Select Done.
