until you stop playback.

When USB cable connection is necessary, connect the USB cable 

supplied with the USB device. See the operation manual supplied 

with the USB device for details on the operation method.

It may take about 10 seconds before “READING” appears depending 

on the type of USB device connected.

Do not connect the system and the USB device through a USB hub.

When the USB device is connected, the system reads all the files on 

the USB device. If there are many folders or files on the USB device, 

it may take a long time to finish reading the USB device.

With some connected USB devices, after an operation is performed, 

there may be a delay before it is performed by this system.

Compatibility with all encoding/writing software cannot be 

guaranteed. If audio files on the USB device were originally encoded 

with incompatible software, those files may produce noise or 

interrupted sound, or may not be played back at all.

This system cannot play audio files on the USB device in the 

following cases;

 when the total number of audio files in a folder exceeds 100.

 when the total number of audio files on a USB device exceeds 

10,000.

 when the total number of folders on a USB device exceeds 100 

(including the “ROOT” folder and empty folders).

  These numbers may vary depending on the file and folder structure. 

Do not save other types of files or unnecessary folders on a USB 

device that has audio files.

The system can play back to a depth of 8 folders only.

This system does not necessarily support all the functions provided 

with a connected USB device.

Resume play will be cancelled when you disconnect the power cord.

Folders that have no audio files are skipped.

The audio formats that you can listen to with this system are as 

follows:

 MP3: file extension “.mp3”

 WMA: file extension “.wma”

 AAC: file extension “.m4a”

  Note that even when file name has the correct file extension, if the 

actual file differs, the system may produce noise or may malfunction.
