Basic Operations
• Transferring stops automatically if:
– the USB device runs out of space during
transferring.
– the number of audio files and folders on the
USB device reaches the limit for the number
that the system can recognize.
– the function or tuner band is changed.
• The maximum number of audio files and
folders may vary depending on the audio file
and folder structure.
• If a folder or file that you are trying to transfer
already exists on the USB device with the
same name, a sequential number is added after
the name without overwriting the original
folder or file.
• Do not remove the USB device during
transferring or erase operations. Doing so may
corrupt the data on the USB device or damage
the USB device itself.
• You cannot eject the disc, select another disc,
track or file, pause playback or find a point in
the track or file during CD-USB
Synchronized Transfer or REC1 Transferring.
• When playing files on the USB device right
after USB transfer, the first-recorded file on
the device is played back.
• Depending on the transferring method, the
transferring progress shown on the display
may vary (1 track/file/folder).
