- There is a possibility that you are using a USB device that consumes high current (such as flash memory or a hard disk) (Warning is displayed on the main unit display if electric current more than the permissible amount flows to the USB device). Use a USB device rated lower than the rating of the unit (5V/2.1A). Alternatively, use a hard disk to which power can be externally supplied through an AC adapter.
- The unit does not support this format. Format the USB device using FAT32, FAT, or HFS+.
- The Mac OS standard format of the GUID partition map is not supported.
- If a USB device is formatted with the Mac Extended format where Case Sensitivity is set, the unit may not recognize the device properly.
- Some USB devices are not recognized, but this problem can be resolved by updating the unit.
