• FAQ:

• • Certain MP3 files are not correctly read by my player.

To start with, make sure that the file’s audio features conform to the specifications of your player (rate, number of channels, resolution, coding type). If all this seems correct, make sure that all the metadata (TAG ID1 and TAG ID2) for your MP3 file are deleted in order to exclusively use the audio information. In fact, certain types of TAGs can prevent the reading of files. There are many functions existing to manage and delete TAGS in your files, but if you do not possess the reference application, you can use the software Winamp (Windows) or Mp3Tag (Windows).

• • Although I have carefully followed the instructions in the user manual, the files and folders do not seem to follow the desired logic.

The problem probably comes from the file and folder names that you have used. So that the Micro Player functioning logic can be applied, the file and folder names must consist of 7 characters, no less and no more. Each character must have a meaning conforming to the user manual and be written in capitals. When this is not the case, the player will apply the default functioning logic.

• • Can I use a Mac OS X system to prepare the contents of my SD card?

When using a Mac OS, the hidden system (. DS_Store, etc.) files generated by this system and which interfere with the proper operation of your player must be deleted manually:

• • • On the MAC computer, insert the storage device.
    • Format the storage device as FAT 32 and give it a volume name.
    • Store on it useful files according to the organization demanded by the player.
    • In the terminal of MAC OS X (folder « Applications » -> « Tools »), enter and execute the following command: dot_clean -m /Volumes/(volume name)
    • Eject the storage device with the ejecting process of the system.
    • Turn the player on with the storage device prepared as follow.

• • My SD card of 4GB (or more) does not function with my player, even though I have correctly formatted it in FAT32.

SD cards of more than 2 GB are SDHC cards (High Capacity SD Cards). The first generation of MicroPlayer, NanoPlayer and NanoPlayer Headphone are not compatible with the SDHC model. Please use a card that is strictly SD of a capacity that is less than or equal to 2GB with The first generation of MicroPlayer, NanoPlayer and NanoPlayer Headphone.

• • When I plug in my cable in the trigger input connector, my player lights up but does not start up when I switch on. However, it functions perfectly when I do not plug the cable in.

Make sure that at no point it is closed off to GND when switch on. When closed off to GND, the player switches into a special mode which prevents start up.

• • I don’t know how my file is encoded. Which software can i use to know precisely which are the caracteristics of my file? (format, type, encoding, bitrate…)

If you have not any software for this, you can use MediaInfo software (http://mediaarea.net/fr/MediaInfo). This software, provided under BSD license, is free and opensource on all operating system (Windows, Mac OS X or Linux).
