To turn on the player
Press the >|| (center round button) button to turn on the player. The player resumes the operation from the point where you last turned off.

To turn off the player
Press and hold the >|| (center round button) button to turn off the player. “POWER OFF” appears.

Hints
If there is no operation for a certain period of time while in stop mode, the display turns off automatically to save the battery power. If there is no operation for an extended period, the player turns off completely. The batteries are consumed a little in this status.

You cannot operate the player when it is connected to a computer. Disconnect the player before operating the player.
