Maximizing Battery Life

By following a few simple guidelines, you can extend the playing time

available from a battery charge.

Screen display auto-off

Setting the display to turn off after a certain period of time of not using the

player (approx. 15 seconds), can help to save battery power.

See "Saving Power Consumption (Power Save)" (  page 41) for the setting

method.

Adjust song format and bit rate

The playing time varies, as battery charge can be affected by the format and bit

rate of the audio songs that are played.

For example, a full battery charge offers about 27 hours of playing time for

songs in ATRAC format at 48 kbps, but only about 19 hours for songs in

WMA format at 128 kbps. The exact playing time available from a full charge

varies with the operating conditions and environment of the player.

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 to the computer directly, 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.
