this unit, to the DC IN 12V jack.
When using AA batteries, set the battery type so that the unit can accurately display the remaining battery charge and determine the necessary minimum remaining charge for operation. (See “Setting the battery type” on page 46.)
CAUTION
Manganese AA batteries cannot be used.
This unit cannot recharge AA nickel-metal hydride
(NiMH) batteries. Use a commercially-available battery
recharger to recharge NiMH batteries.
Ahook(cordholder)toxthecordoftheACadaptor
is on the right side panel. Wrap the cord around the hook when connecting it to prevent it from being disconnected during use.
CAUTION
Use only the included PS-1225L AC adaptor, which conforms to the specifications of this unit. Use of an adaptor other than this model could cause malfunction, fire or electric shock.

TIP
You can also use the computer to manage the
contents of the “MUSIC” folder.
You can create subfolders inside the “MUSIC”
folder, but this unit can only recognize one level of
subfolders. The unit ignores deeper folder levels and the files in them.
Since this unit can be set to play the contents of a
single folder, organizing folders by musical category or
artist could be convenient.
Names given to subfolders and files are shown on the
unit’s Home Screen and the BROWSE screen.
This unit can only read files and folders with names
that contain only single-byte alphanumeric characters.

Ending the connection with a computer

Follow the correct computer procedures to disconnect the unit from the computer before disconnecting the USB cable. Please refer to your computer manual for information about the correct procedures for discon­necting an external drive.
After being disconnected, the power is set to standby.
