Inserting batteries

Main unit

PREPARATION

NOTE

• The power will not be supplied through the batteries when the power is supplied

through the AC outlet or car battery on the unit.

• The battery is consumed more quickly than usual when operating the unit

continuously or operating it in a cold place.

• When the power is supplied using the batteries, the display will be blank when the

unit is turned off (at standby).

• When the power is supplied using the batteries, the unit is turned on by pressing

or source buttons on the main unit.

CAUTION

To avoid battery leakage or explosion, handle batteries properly.

• If you are not going to use this unit for a month or more, remove the batteries from

the battery compartment.

• Dispose of batteries in the proper manner, according to federal, state, and local

regulations.

• Do not mix with batteries of different types or with new and old ones.

• Do not attempt to charge any batteries other than rechargeable ones.

• Discard leaky batteries immediately. Battery leakage can cause skin burns or other

personal injuries.

• If chemicals leak onto the unit, clean the unit completely.

Match the polarities (+ and –) of the batteries.

Remote control

• If the range or effectiveness of the remote control decreases, replace the batteries.

Cautions when connecting to the car adapter

• Be sure to use the car adapter (not supplied) with the same

polarity design as the one equipped with this unit to prevent

mishaps or damage.

• For safety, stop the car before performing operations.

• Be sure to start the engine when you use the car adapter;

otherwise, the car battery will be exhausted.

Hierarchy

Level 1 Level 2 Level 3 Level 4 Level 5

Folder with its play order

MP3/WMA track with its play order

MP3/WMA folders/tracks configuration

• MP3/WMA discs require a longer readout

time than regular CDs. (It depends on the

complexity of the folder/file configuration.)

• Some MP3/WMA files cannot be played back

and will be skipped. This results from their

recording processes and conditions.

• When making MP3/WMA discs, use ISO 9660

Level 1 for the disc format.

• This unit can play back MP3/WMA files with

the extension code <.mp3> or <.wma>

(regardless of the letter case upper/lower).

• It is recommended that you make each MP3

file at a sampling rate of 44.1 kHz and at a bit

rate of 128 kbps. Similarly each WMA file at a

sampling rate of 44.1 kHz and at a bit rate of

96 kbps.

• Playback order of MP3/ WMA files may be

different from the one you have intended

when recording. If a folder does not contain

MP3/ WMA files, it is ignored.

• This unit cannot play “packet write” discs.

• If a CD-RW has been recorded in a different

format, erase all data on the CD-RW

completely before recording on it.

• This unit can recognize up to a total of 511

tracks and folders on a disc, and 65536 files

in up to 200 groups (maximum 500 files in a

single group) on a USB device.

For connecting/disconnecting:

• USB Memory and DAPs compatible with the USB

mass storage class specifications are connectable.

• Always set the volume to the minimum level when

connecting or disconnecting a USB device.

• When connecting with a USB cable, use the USB 2.0

cable less than 1 m (3.28 ft) in length.

• You cannot connect a computer to the USB

MEMORY terminal of the unit.

• Connect one USB device to the unit at a time. Do

not use a USB hub.

• When the power is supplied through the AC outlet

or car battery and USB is selected as the source, the

USB device is charged through the USB MEMORY

terminal, however some USB devices may not be

charged.

For playing back:

• When connecting a USB device, refer also to its

manual.

• You can play back MP3/WMA files on a USB device

(maximum data transfer rate: 2 Mbps). This unit may

not play back some files even though their formats

are listed above.

• While playing back a file in a USB device, do

not disconnect the USB device. It may cause

malfunction of both this unit and the device.

• This unit is compatible with USB 2.0 Full Speed.

• You cannot play back a file larger than 2 Gigabytes.

• When playing a file of a large transfer rate, sounds

may be dropped during playback.

• This unit cannot recognize a USB mass storage class

device whose rating exceeds 5V/500 mA.

• You cannot send any data to your USB device from

this unit.

• Some USB devices may not be recognized or may

not work properly.

• Some DAPs are not compatible with the unit.

• Copyrighted tracks (WMA-DRM* tracks) cannot be

played back on the unit.

• Coded or encrypted tracks in a special method

cannot be played on the unit.

• Avoid exposure to direct sunlight,

temperature extremes, and moisture.

Cleaning discs

• Wipe the disc with a soft cloth in a straight

line from center to edge.
