Marantz does not guarantee that all USB flash drives will operate or receive power. When using a portable USB hard disk drive (HDD) which came with an AC adapter, use that device’s supplied AC adapter.

NOTE

USB flash drives will not work via a USB hub.

It is not possible to use this unit by connecting the unit’s USB port to a PC via a USB cable.

Do not use an extension cable when connecting a USB flash drive. This may cause radio interference with other devices.
