About USB memory
USB is an acronym for Universal Serial Bus, and refers to an external bus standard supporting data transfer rates of 12 Mbps.
This unit is compatible with USB 1.1/2.0 with maximum data transfer rates of 12 Mbps. USB memory devices that can be played by connecting to the unit’s USB cable are limited to those recognized as “USB mass storage class devices”; operation is not guaranteed with all USB memory devices.
∗Devices compatible with “USB Mass Storage Class” can be used merely by connecting to the host device, without need for special drivers or application software.
Consult the manufacturer of your USB memory device for information regarding whether it is supported by “USB Mass Storage Class” standards.
Audio files playable on this unit are limited to MP3/WMA/AAC files.
To prevent the accidental loss of data, always back up important data on your computer. This unit does not support connections to a com- puter. In addition, connections made through a USB hub device are also not supported. When a USB memory device is composed of two or more drives, only one of the drives will be detected.
USB memory devices with security functions cannot be played.
The order in which tracks are recorded may dif- fer depending on the USB memory device con- nected (the actual playback order may not be the same as that indicated on your computer’s display).
If you continuously operate folder up/down, the play time keeps as “00:00”, and the sound is not emitted.
What is MP3?
MP3 is an audio compression method and clas- sified into audio layer 3 of MPEG standards. This audio compression method has penetrated into PC users and become a standard format. This MP3 features the original audio data compres- sion to about 10 percent of its initial size with a high sound quality. This means that several mu- sic CDs can be recorded on a USB memory de- vice to allow a long listening time∗.
∗Depends on the USB memory device storage capacity.
