How to use the number buttons:  
If you press MODE, the unit goes into functions mode and the number buttons work as different  
function buttons.  
Time countdown indicator  
«
Ex.: When you press button 5 to enter the RPT  
function mode.  
To use these buttons as number buttons again after pressing MODE, wait for 5 seconds without  
pressing any number button until the functions mode is cleared.

CAUTION on Volume Setting  
CDs produce very little noise compared with other sources. If the volume level is adjusted for the tuner, for  
example, the speakers may be damaged by the sudden increase in the output level. Therefore, lower the  
volume before playing a disc and adjust it as required during playback.

the sound modes simply by changing the sources.  
When shipped from the factory, this mode is  
deactivated.  
In this case, set the dimmer mode to “ON” or “OFF.”  
To turn on/off the key-touch tone – BEEP

MAINTENANCE  
Handling discs  
Moisture condensation  
Moisture may condense on the lens inside the  
unit in the following cases:  
• After starting the heater in the car.  
• If it becomes very humid inside the car.  
Should this occur, the unit may malfunction. In  
this case, eject the disc and leave the unit  
turned on for a few hours until the moisture  
evaporates.  
This unit has been designed to reproduce CDs  
and CD-Rs.  
• You can play back your original CD-Rs  
(Recordable) and CD-RWs (Rewritable) on this  
receiver.  
This unit is not compatible with MP3.  
How to handle discs  
When removing a disc  
When playing a CD-R or CD-RW  
User-edited CD-Rs (Recordable) and CD-RWs  
(Rewritable), can be played back only if they are  
already “finalized.”  
• You can play back your original CD-Rs or  
CD-RWs recorded in music CD format.  
(However, they may not be played back  
depending on their characteristics or recording  
conditions.)  
Center holder  
from its case, press  
down the center holder of  
the case and lift the disc  
out, holding it by the  
edges.  
• Always hold the disc by  
the edges. Do not touch its recording surface.  
• Before playing back CD-Rs or CD-RWs, read  
their instructions or cautions carefully.  
• Some CD-Rs or CD-RWs may not be played  
back on this unit because of their disc  
characteristics, damage or stain on them, or if  
the player’s lens is dirty.  
When storing a disc into its case, gently insert  
the disc around the center holder (with the  
printed surface facing up).  
• Make sure to store discs into the cases after  
use.  
• CD-Rs or CD-RWs are susceptible to high  
temperatures or high humidity; so do not leave  
them inside your car.  
• CD-RWs may require a longer readout time.  
(This is caused by the fact that the reflectance  
of CD-RWs is lower than for regular CDs.)  
To keep discs clean  
A dirty disc may not play  
correctly. If a disc does become  
dirty, wipe it with a soft cloth in  
a straight line from center to  
edge.  
To play new discs  
CAUTIONS:  
New discs may have some  
rough spots around the inner  
and outer edges. If such a disc  
is used, this unit may reject the  
disc.  
Do not insert 8 cm (3 3/16") discs (single CDs)  
into the loading slot. (Such discs cannot be  
ejected.)  
Do not insert any disc of unusual shape — like a  
heart or flower; otherwise, it will cause a  
malfunction.  
Do not expose discs 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.  
To remove these rough spots, rub the edges with  
a pencil or ball-point pen, etc.  
About mistracking:  
Do not use any solvent (for example, conventional  
record cleaner, spray, thinner, benzine, etc.) to  
clean discs.  
Mistracking may result from driving on  
extremely rough roads. This does not damage  
the unit and the disc, but will be annoying.  
We recommend that you stop disc playback  
while driving on such rough roads.
