To remove the USB adaptor from the player While pressing the gray buttons on both sides, push the USB adaptor inward, and then pull it outward. Notes on the AC power adaptor • Use only the AC power adaptor and the USB adaptor supplied with the player. Do not use any other AC power adaptor since this may cause the player to malfunction. Getting Started Charging the battery using a USB connection Turn on your computer and connect the USB cable to your computer ( page 14). The CHG lamp lights up on the USB adaptor and charging of the battery starts. It takes approximately 5 hours to charge. When the player is connected to the AC power adaptor, the power is supplied from the AC power adaptor. Notes • When charging the battery using a USB connection, if your computer's power supply is insufficient, the charging time will be longer. • When charging the battery using a USB connection, the charging will stop depending on your system environment. • If the player is connected to the computer for a long time while charging, charging may stop to prevent the temperature of the player from increasing too much. In this case, the CHG lamp goes out. Remove the USB adaptor from the player and start charging again after a while. • If the player will not be used for three months or more, set the BUILT-IN BATTERY switch to OFF to prevent degradation of the battery. • Charge the battery in an ambient temperature of between 5 to 35ºC (41 to 95ºF). • The player is not disconnected from the AC power source (mains) as long as it is connected to the wall outlet, even if the player itself has been turned off. • If you are not going to use the player for a long time, be sure to disconnect the power supply. To remove the AC power adaptor from the wall outlet, grasp the adaptor plug itself; never pull the cord.

Notes • The display shows the approximate battery power remaining.
