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.
Set the screen
A "Display Time" setting of "15 sec," a "New Song Pop Up" setting of "Off,"
and a "Screensaver" setting of "None" offer longer battery life than other
settings.
Adjust the brightness of the screen
Setting "Brightness" to the lower setting reduces battery use while the display
is on (  page 57).
Set the sound quality off
A "Sound" setting of "None" offers longer battery life than the other sound
quality options (  page 48).
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.
