Turning on/off the BBEII function  
The BBEII* function restores the brilliance and clarity of the original live sound in recording,  
broadcasts, etc.  
When a speaker reproduces sound, it introduces frequency-dependent phase shifting, causing  
high-frequency sounds to take longer to reach the ear than low frequency sounds.The BBEII  
function adjusts the phase relationship between the low, mid and high frequencies by adding  
a progressively longer delay time to the low and mid frequencies, so that all frequencies  
reach the listeners ears at the proper time.  
In addition, the BBEII function boosts low and high frequencies, which loudspeakers tend to  
be less efficient in reproducing, through dynamic, program-driven augmentation. When  
combined with the phase compensation feature, the resulting sound has a clearer, more  
finely detailed livepresence.  
BBE  
Each time you press BBE, the BBEII function changes as follows.  
As the number gets higher, the BBEII function becomes stronger. The initial setting is BBE 2.

CD CHANGER OPERATIONS  
We recommend that you use one of the CH-X series (ex: CH-X1200) with your unit.  
If you have another CD automatic changer, consult your JVC car audio dealer for connections.  
• For example, if your CD automatic changer is one of the KD-MK series, you need a cord (KS-U15K)  
for connecting it to this unit.  
Before operating your CD automatic changer:  
• Refer also to the Instructions supplied with your CD changer.  
• If no discs are in the magazine of the CD changer or the discs are inserted upside  
down, “NO DISC” will appear on the display. If this happens, remove the magazine and  
set the discs correctly.  
• If “RESET 1 - RESET 8appears on the display, something is wrong with the connection  
between this unit and the CD changer. If this happens, check the connection, connect  
the connecting cord(s) firmly if necessary, then press the reset button of the CD changer.

DIGITAL AUDIO  
Ho w to h a n d le CDs  
When removing a CD from its case, press down the center holder of the case and  
lift the CD out, holding it by the edges.  
Center holder  
• Always hold the CD by the edges. Do not touch its recording surface.  
When storing a CD into its case, gently insert the CD around the center holder  
(with the printed surface facing up).  
• Make sure to store CDs into the cases after use.  
To k e e p CDs cle a n  
A dirty CD may not play correctly. If a CD does become dirty, wipe it with a soft cloth in  
a straight line from center to edge.  
To p la y n e w CDs  
New CDs may have some rough spots around the inner and outer edges. If such a CD  
is used, this unit may reject the CD.  
To remove these rough spots, rub the edges with a pencil or ball-point pen, etc.  
Mo istu re co n d e n sa tio n  
Moisture may condense on the lens inside the CD player in the following cases:  
• After starting the heater in the car.  
• If it becomes very humid inside the car.  
Should this occur, the CD player may malfunction. In this case, eject the CD and leave  
the unit turned on for a few hours until the moisture evaporates.  
CAUTIONS:  
Do not insert 8cm (3 3/16") CDs (single CDs) into the loading slot. (Such CDs cannot be ejected.)  
Do not insert any CD of unusual shape – like a heart or flower; otherwise, it will cause a malfunction.  
Do not expose CDs to direct sunlight or any heat source or place them in a place subject to high temperature and  
humidity. Do not leave them in a car.  
Do not use any solvent (for example, conventional record cleaner, spray, thinner, benzine, etc.) to clean CDs.  
W h e n p la y in g a CD-R (Re co rd a b le )  
You can play back your original CD-Rs on this receiver.  
• Before playing back CD-Rs, read their instructions or cautions carefully.  
• Some CD-Rs recorded on CD recorders may not be played back on this receiver because of their disc  
characteristics, and of the following reasons:  
– Discs are dirty or scratched.  
– Moisture condensation occurs on the lens inside the unit.  
– The pickup lens inside the CD player is dirty.  
• Use only “finalized” CD-Rs.  
• CD-RWs (Rewritable) cannot be played back on this receiver.  
• Do not use the CD-Rs with stickers or sticking labels on the surface. They may cause malfunctions.  
About mistracking:  
Mistracking may result from driving on extremely rough roads. This does not damage the unit and  
the CD, but will be annoying.  
We recommend that you stop CD play while driving on such rough roads.
