SmartDisk MP3 - Manual (Page 8)

Your battery was fully charged before it left the factory, but it may have lost some
charge during shipping. SmartDisk recommends that you charge the battery before
you begin using it. To allow your FlashTrax to begin charging the battery, connect
the small end of the AC Power Adapter to the power jack on the right side of your
FlashTrax and plug the other end into any standard electrical outlet.
When your FlashTrax is plugged in, the CHARGE light on
the front of the unit will be lit. When the light is red, your
FlashTrax is charging the battery. When the light is green,
your FlashTrax has finished charging. You can continue to
use your FlashTrax normally while it is charging.
