Does the TD support the sampling
frequency and bit rate of the MP3 file, or

of a high bit-rate MP3.

flash drive?
Delete unneeded files from the USB flash
drive, or use a higher-capacity USB flash
drive.
Can’t correctly set the A-B repeat times
It’s not possible to set the “A” and “B” times
any closer than one second.
Make sure that there is at least one second
between the two times.
When using an MP3 file, it might not be possible to play back the A-B repeat region
correctly.

Is the TD correctly connected to your
computer?
Check the connection to your computer.
Is the USB driver installed?
You must first install the USB driver in your

the TD to your computer’s USB port is
compatible with USB 2.0 Hi-Speed.

USB 2.0 Hi-Speed.
