when the player is
operated.
The player gets warm.
The date and time have

All settings of the player
have been reset.
Cause/Remedy
 "Beep" is set to "Beep OFF. "
 Set "Beep" to "Beep ON" (  page 46).
 The player may be warm when the battery is being charged and
just after charging. The player also may become warm when a
large amount of files are transferred. This is normal and is not
cause for concern. Set the player aside for a while to allow it to
cool down.
 If you left the player for a while with the battery used up, the
date and time may be reset.
 This is not a malfunction. Charge the battery until
appears on the screen (  page 14) and set the date and
time again (  page 17, 45).
 You moved, deleted, or renamed the system files. Or, the built-
in flash memory of the player was formatted using other than
the "Format" menu of the player.
 If you do any of the above operations, the system will be
restructured and all settings of the player will be reset when
you disconnect the player from the computer or other
devices.
If the player does not function normally after you format
the player using other than the "Format" menu of the player,
format the built-in flash memory using the "Format" menu
of the player (  page 51).
