DAB tuner operations

What is DAB system?
Digital Audio Broadcasting (DAB) can deliver digital quality sound without any annoying interference and signal distortion. Furthermore, it can carry text, pictures, and data. When transmitting, DAB combines several programmes (called services) to form one ensemble. In addition, each servicecalled primary servicecan also be divided into its components (called secondary service). A typical ensemble has six or more programmes (services) broadcast at the same time. By connecting the DAB tuner, this unit can do the following: Tracing the same programme automatically Alternative Frequency Reception (see DAB AF on page 14). It is recommended to use DAB tuner KT-DB1000 with your unit. If you have another DAB tuner, consult your JVC IN-CAR ENTERTAINMENT dealer. Refer also to the Instructions supplied for your DAB tuner.
Start searching for an ensemble.
When an ensemble is received, searching stops. To stop searching, press the same button again.

Caution for DualDisc playback
The Non-DVD side of a DualDisc does not comply with the Compact Disc Digital Audio standard. Therefore, the use of Non-DVD side of a DualDisc on this product may not be recommended.
Do not use the following CD-Rs or CD-RWs: Discs with stickers, labels, or protective seal stuck to the surface. Discs on which labels can be directly printed by an ink jet printer. Using these discs under high temperatures or high humidities may cause malfunctions or damage to the unit.

Playing an MP3/WMA disc

This unit can play back MP3/WMA files with the extension code <.mp3> or <.wma> (regardless of the letter caseupper/lower). This unit can show the names of albums, artists (performer), and Tag (Version 1.0, 1.1, 2.2, 2.3, or 2.4) for MP3 files and for WMA files. This unit can display only one-byte characters. No other characters can be correctly displayed. This unit can play back MP3/WMA files meeting the conditions below: Bit rate: 8 kbps 320 kbps Sampling frequency: 48 kHz, 44.1 kHz, 32 kHz (for MPEG-1) 24 kHz, 22.05 kHz, 16 kHz (for MPEG-2) Disc format: ISO 9660 Level 1/ Level 2, Romeo, Joliet, Windows long file name The maximum number of characters for file/folder names vary among the disc format used (includes 4 extension characters<.mp3> or <.wma>). ISO 9660 Level 1: up to 12 characters ISO 9660 Level 2: up to 31 characters Romeo: up to 128 characters Joliet: up to 64 characters Windows long file name: up to 128 characters This unit can recognize a total of 512 files, of 200 folders, and of 8 hierarchies. This unit can play back files recorded in VBR (variable bit rate). Files recorded in VBR have a discrepancy in elapsed time display, and do not show the actual elapsed time. Especially, after performing the search function, this difference becomes noticeable.


This unit has been designed to reproduce CDs/CD Texts, and CD-Rs (Recordable)/CD-RWs (Rewritable) in audio CD (CD-DA), MP3 and WMA formats. When a disc is inserted upside down, PLEASE and EJECT appear alternately on the display. Press 0 to eject the disc. While fast-forwarding or reversing on an MP3 or WMA disc, you can only hear intermittent sounds.
