10、compressing MP3 and WMA files as follows:MP3 Files: 128kbps recommended (32kbps-320kbps)WMA Files: 128kbps recommended (64kbps-160kbps) This unit is compatible with 32kHz, 44.1kHz (recommended)and 48kHz sampling frequencies.Categorizing foldersAs MP3 and WMA files are compressed into high-quality so
11、undfiles at an extremely high rate of compression, it is possible torecord several times more tracks than audio CDs onto a singlemedium. It is therefore convenient to split the tracks into differ-ent folders by genre, artist or album for retrieval and repeat play-back purposes. A maximum of 23 folde
12、rs or a maximum of 200 files can bestored on a single media. There are cases where it is not possible to save folders in thedesired sequence depending on the software being used.Naming filesSingle-byte characters between A and Z, single-byte numeralsbetween 0 and 9, and the single-byte underscore (_
13、) can beused when naming files. A maximum of twelve characters canbe displayed. Ensure that the .MP3 (MP3 files) or .WMA(WMA files) extension logs are attached to all file names. Never add the MP3 or WMA extension logs to any files otherthan MP3 and WMA files. If the MP3 or WMA extension logsare add
14、ed to any files other than MP3 and WMA files, theequipment will assume that they can be played back, and thiswill produce loud noises in the headphones, resulting in dam-age of adverse effects.Hint for when naming folders and filesWhen media containing MP3 and WMA files are played back onthis equipm
15、ent, the sequence in which each track is played backwill be the same as the sequence in which they were saved. It ispossible to set up the playback sequence by adding numbersfrom between 01 and 99 to the front of the folder and the filename when saving the file. There are cases where it is not possi
16、ble to save files in thedesired sequence depending on the software being used.Additional informationDepending on the MP3 and WMA compression software in use,it is possible to save track titles, artist names and other informa-tion together with each sound file as additional information.Although it is
17、 possible to display pre-recorded title and artistinformation with this information, it is necessary to ensure thatthis information has been entered in single-byte alphanumericals(Up to a maximum of 30 alphanumericals for each.). The method of entering title and artist information will differ inacco
18、rdance with the compression software. Refer to the com-pression softwares instruction manual or help file.Confirming media and filesCheck to ascertain that MP3 and WMA files can be played backcorrectly on the personal computer in use prior to saving themonto the media. Check to ensure that the saved
19、 file can beplayed back normally. It is not possible to confirm that files can be played back cor-rectly while they are being saved onto the media.When saving files onto mediaEnsure that the session is closed or finalized when data hasbeen written on media. There are cases where media on whichthe se
20、ssion has not be closed or finalized will not be playedback correctly with this equipment. There are cases were the folder names and file names will notbe displayed correctly depending on the software used tosave them. Do not store files or folders other than MP3 and WMA onmedia to be played back wi
21、th this equipment. It is recommended that ten or less sessions are stored whenrecording MP3 and WMA files onto a medium. There are cases where playback is not possible when MP3and WMA files (CD-ROM) and music CD information (CD-DA)are saved on the same media.Remote controller(A70-1490-05)Rechargeabl
