4. PRECAUTIONS  
1. When the inside of the car is very cold and the  
player is used soon after switching on the  
heater, moisture may form on the disc or the  
optical parts of the player and proper playback  
may not be possible. If moisture forms on the  
disc, wipe it off with a soft cloth. If moisture  
forms on the optical parts of the player, do not  
use the player for about one hour and the con-  
densation will disappear naturally to allow nor-  
mal operation.  
2. Driving on extremely bumpy roads which cause  
severe vibration may cause the sound to skip.  
3. This unit uses a precision mechanism.  
Even in the event that trouble arises, never  
open the case, disassemble the unit, or  
lubricate the rotating parts.  
This equipment has been tested and found to  
comply with the limits for a Class B digital device,  
pursuant to Part 15 of the FCC Rules.  
!
CAUTION  
USE OF CONTROLS, ADJUSTMENTS, OR  
PERFORMANCE OF PROCEDURES OTHER  
THAN THOSE SPECIFIED HEREIN, MAY  
RESULT IN HAZARDOUS RADIATION EX-  
POSURE.  
These limits are designed to provide reasonable  
protection against harmful interference in a resi-  
dential installation.  
This equipment generates, uses, and can radiate  
radio frequency energy and, if not installed and  
used in accordance with the instructions, may  
cause harmful interference to radio communica-  
tions. However, there is no guarantee that inter-  
ference will not occur in a particular installation.  
THE COMPACT DISC PLAYER SHOULD  
NOT BE ADJUSTED OR REPAIRED BY  
ANYONE EXCEPT PROPERLY QUALIFIED  
SERVICE PERSONNEL.  
If this equipment does cause harmful interference  
to radio or television reception, which can be de-  
termined by turning the equipment off and on, the  
user is encouraged to consult the dealer or an  
experienced radio/TV technician for help.  
INFORMATION FOR USERS:.  
CHANGES OR MODIFICATIONS TO THIS  
PRODUCT NOT APPROVED BY THE MANU-  
FACTURER WILL VOID THE WARRANTY

Flip Down Panel  
This unit uses a flip-down structure that makes possible large-size displays.  
CAUTION  
!
When opening and closing the FLIP DOWN PANEL, be careful not to catch your fingers. They  
could be injured.  
1. Always use this unit with the FLIP DOWN  
PANEL closed.  
4. When closing the FLIP DOWN PANEL, do not  
[
]
press the OPEN button.  
2. Do not force operations or use this device ab-  
normally when opening or closing the FLIP  
DOWN PANEL.  
5. Strong impacts to the operating or display sec-  
tion can cause damage or deformation.  
6. If the FLIP DOWN PANEL does not open fully,  
gently open it with your hand.  
3. Do not use the FLIP DOWN PANEL as a tray  
to place objects on when it is open.  
Handling Compact Discs  
Use only compact discs bearing the

specially shaped compact dics.  
Some CDs recorded in CD-R/CD-RW mode may  
not be usable.  
mark.  
Do not use compact discs that have large  
scratches, are misshapen, cracked, etc. Use  
of such discs may cause misoperation or dam-  
age.  
To remove a compact disc from its storage  
case, press down on the center of the case  
and lift the disc out, holding it carefully by the  
edges.  
Do not use commercially available CD pro-  
tection sheets or discs equipped with stabi-  
lizers, etc. These may damage the disc or  
cause breakdown of the internal mechanism.  
Handling  
Compared to ordinary music CDs, CD-R and  
CD-RW discs are both easily affected by high  
temperature and humidity and some of CD-R  
and CD-RW discs may not be played. There-  
fore, do not leave them for a long time in the  
car.  
New discs may have some roughness around  
the edges. If such discs are used, the player  
may not work or the sound may skip. Use a  
ball-point pen or the like to remove any rough-  
ness from the edge of the disc.  
Storage  
Do not expose compact discs to direct sun-  
light or any heat source.  
Do not expose compact discs to excess hu-  
midity or dust.  
Do not expose compact discs to direct heat  
from heaters.  
Ball-point pen  
Roughness  
Cleaning  
To remove fingermarks and dust, use a soft  
cloth and wipe in a straight line from the cen-  
ter of the compact disc to the circumference.  
Do not use any solvents, such as commer-  
cially available cleaners, anti-static spray, or  
thinner to clean compact discs.  
After using special compact disc cleaner, let  
the compact disc dry off well before playing  
it.  
Never stick labels on the surface of the com-  
pact disc or mark the surface with a pencil or  
pen.  
Never play a compact disc with any cello-  
phane tape or other glue on it or with peeling  
off marks. If you try to play such a compact  
disc, you may not be able to get it back out of  
the CD player or it may damage the CD  
player.
