Additional Information
Learning More about This System
Daily Operations—Playback
(see pages 7 to 10)
Listening to the Radio:
• If you store a new station into an occupied preset number,
the previously stored station in that number will be erased.
• When you unplug the AC power cord or if a power failure
occurs, the preset stations will be erased in a few days. If this
happens, preset the stations again.
Playable Media and Files:
• This System cannot play “packet write” discs.
• For MP3/WMA playback...
– MP3/WMA discs are required a longer readout time than
regular CDs. (It depends on the complexity of the group/
file configuration.)
– Some MP3/WMA files cannot be played back and will be
skipped. This results from their recording processes and
conditions.
– When making MP3/WMA discs, use ISO 9660 Level 1 or
Level 2 for the disc format.
– This System can play back MP3/WMA files with the
extension code <.mp3/.wma> (regardless of the letter
case—upper/lower).
– Some characters or symbols will not be shown correctly
on the display.
The maximum character number shown on the display is
32 (without the extension code) for file names, and 30 for
ID3 tag.
– It is recommended that you make each MP3/WMA file at
a sampling rate of 44.1 kHz and at bit rate of 128 kbps.
– This System can recognize a total of 999 tracks and 99
groups. Those exceeding the maximum number cannot be
recognized.
– If a folder does not include MP3/WMA tracks, they are
ignored.
– Playback order of MP3/WMA tracks may be different
from the one you have intended while recording. If a
folder does not include MP3/WMA tracks, they are
ignored.
• For playback of files in the USB mass storage class device...
– Connect one USB mass storage class device directly to the
System at a time. Do not use a USB hub.
– Coded or encrypted tracks in a special method cannot be
played on the System.
– The USB mass storage class device’s battery is charged
while the System is turned on.
– This System cannot recognize a USB mass storage class
device whose rating exceeds 5 V/500 mA.
– This System is compatible with the USB 2.0 Full-Speed.
– You cannot play back a file larger than 2 GB.
– When playing a file which has a large transfer rate, sounds
may be dropped during playback.
– Some USB mass storage class devices may not be
recognized or may not work properly.
– The compatible format is FAT16/FAT32.
– JVC bears no responsibility for any loss of data in the USB
mass storage class device while using this System.
Playing Back Other Equipment
• If the audio output on other equipment is not stereo mini
plug type, use a plug adapter to convert the stereo mini
plug to the corresponding plug of the audio output. Refer
to the manuals supplied with the other equipment.
