Table of Contents Menu Index 63 Advanced Features 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 54) 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 18 hours of playing time for songs in ATRAC format at 48 kbps, but only about 15 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. To deactivate the G Sensor The player's built-in G Sensor recognizes speed variation and provides various functions. However, with the G Sensor active, battery consumption is higher when G Sensor active than when not. In order to save power and prolong use of the player, it is recommended to deactivate the G Sensor ( page 40). To make the player enter Sleep status When you stop song playback or FM reception (NW-S202F/S203F/S205F only) by pressing the  button, after about a few seconds, the display goes off automatically and the player enters Sleep status. When the G Sensor menu is deactivated in Sleep status, the player consumes very little battery power. 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.
