Using USB memory devices
This section describes how to use your radio to access and playback your
audio files via USB memory devices.
USB memory devices plug into the rectangular slot on the rear of the
radio.
Important: Your radio is only designed to work with USB flash memory
devices. It is not intended to be connected to hard disk drives or any other
type of USB device.
The Stream 205 radio has been tested with a range of USB memory devices
of up to 64GB capacity. USB memory must use the FAT or FAT 32 filing
system in order to operate with the radio.
It is possible to use SD or SDHC cards for media storage and playback
when held in a suitable USB adaptor. However, due to the wide variation
of such adaptors, it is not possible to guarantee that all adaptor / card
combinations will work in the radio.
Audio formats supported are MP3, WMA, AAC, FLAC and WAV.
USB playback does not support files encoded using WMA Lossless,
WMA Voice, WMA 10 Professional, nor files of any format which have
DRM protection.
Recommendations:
Unless you have only a few files on the USB memory device, do not
place all files in the root folder.
The number of items (files/sub directories) in any directory should be
less than 2000.
Searching and playback will be more responsive if the number of files
in any one folder is limited (we suggest not more than 250).
It is recommended that the USB memory is reformatted in your computer
before adding your music files.
The maximum depth of folder nesting permitted is 8 directory levels
(but playback is only from the currently selected folder).
Shuffle and Playlist functions are limited to 500 tracks.
Cautions:
In order to minimise the risk of damage to your radio or your USB
memory, please place the unit such that the memory device cannot
easily be knocked while it is inserted in the socket. Take care to avoid
knocking the USB memory device with the radio's carry handle.
Remove the USB memory before carrying the unit or if not using the
USB feature for a prolonged period.
Place the unit in Standby mode before removing your USB memory
device.
