To Remove the USB device

Do the following: Hold down x (stop) on the unit until No Device appears, then disconnect the USB device.
You can use the system as a battery charger for USB devices that have a rechargeable function when the system is on. The charging begins when the USB device is connected to the (USB) port. The charge status appears in the USB device display. For details, see the operating manual supplied with your USB device.
*1 When playing a VBR MP3/WMA file, the system may resume playback from a different point. *2 You cannot select a memory during playback. Make sure to select a memory before starting playback.
When USB cable connection is necessary, connect the
USB cable supplied with the USB device to be connected. See the operating manual supplied with the USB device to be connected 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 audio, or may not play at all. This system cannot play audio files on the USB device in the following cases: when the number of audio files in a folder exceeds 999. when the total number of audio files on a USB device exceeds 999. when the number of folders on a USB device exceeds 999 (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 in a connected USB device. Resume play is canceled when you turn off the system. 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 the file name has the correct file extension, if the actual file differs, the system may produce noise or may malfunction.

PARTY STREAMING in a wireless LAN environment
With some IEEE802.11n-compatible wireless LAN routers/access points, the wireless LAN transfer speed may slow down when WEP or WPA/WPA2-PSK (TKIP) is selected for the encryption method. If the sound skips during streaming playback using the PARTY STREAMING function, try changing the encryption method to WPA/ WPA2-PSK (AES). This may improve the transfer speed and the streaming playback. Configurations of encryption vary depending on the model; please refer to the operating instructions supplied with your router/access point. You can also obtain support information about wireless LAN settings on the following website. http://www.sony.net/audio/netsettings
