9. Appendix

9.1. Precautions When Using the USB TO DEVICE connector

● USB devices that can be used

・Use a USB flash drive. Other USB devices (such as USB hubs, mice, and computer keyboards) cannot be used even if they are connected. This device can be used with USB 1.1 to 2.0 USB flash drives. (However, operation of all USB flash drives is not guaranteed.)

The rated output of the USB port is 5 V / 500 mA max. If a device requiring more than 500mA of current is connected, the power supply will be cut off. In this case, rebooting the device is required to resume power supply.

● Supported file specifications

WAV files
File extension .wav only.
Sampling rates of 44.1 kHz, 48 kHz, 88.2 kHz, and 96 kHz are supported.
16-bit, 24-bit and 32-bit PCM mono and stereo are supported.

MP3 files
Only one MPEG audio is supported.
Layer 3 is supported (only files with the mp3 extension). Free format is not supported.
Sample rates of 32kHz, 44.1kHz, and 48kHz are supported. Bit rates of 32 to 320kbps and VBR (Variable Bit Rate) are supported.

● Connecting a USB flash drive

・ Do not insert or remove the USB flash drive while a file operation is in progress. Also, do not turn off the power during file operations. Doing so may cause the device to stop functioning or may corrupt the USB flash drive or its data. Wait at least six seconds before reinserting a USB flash drive after removal.

important Notice

  • If you use a USB extension cable, use one that is 1m or less in length.

● Formatting a USB flash drive

Use a USB flash drive formatted to FAT32 or FAT16. Format the USB flash drive on a computer. USB flash drives formatted on other equipment may not work properly with this device.

● Preventing accidental erasure

Some USB flash drives have a write-protect function to prevent accidental erasure of their data. If the USB flash drive contains important data, write-protect it to prevent overwriting.
