Using USB memory devices

This section describes how to use your radio to access and playback your

audio files via USB memory devices.
1. USB memory devices plug into the rectangular slot on the top of your

radio on the left hand side.

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 iStream 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 so that the memory device cannot be

easily knocked while it is inserted in the socket.

Remove the USB memory before carrying the unit or if not using the

USB feature for a prolonged period.

Place the unit in Stand-by mode before removing your USB memory

device.
