Maximizing Battery Life
By following a few simple guidelines, you can extend the playing time available from a battery charge.
Turn off the player manually
Although the player turns off automatically if left in pause mode for a few minutes, you can save some battery power by manually turning off the player when you are finished using it.
To turn off the player, press and hold OPTION, or select “Shut Down” from the Option menu of any screen.
Adjust the player display time
A “Display” setting of “15 sec” offers longer battery than the other Display Time options ( page 50).
Adjust the brightness of the screen
Setting “Brightness” to the lower setting reduces battery use while the display is on ( page 51).
Setting the sound quality off
A “Sound” setting of “None” offers longer battery life than the other sound quality options ( page 45).
Do not let your computer sleep when the player is connected
If the computer enters a power saving mode, such as the system suspend, sleep or hibernation while the player is connected via the USB cable, the player’s battery is not charged. Instead, the player continues to draw power from the battery, discharging it.
Note
•Do not leave the player connected for extended periods to a laptop computer that is not connected to AC power, because the player may discharge the computer’s battery.
