FCC WARNING  
Precautions  
Handling the Front Panel  
This equipment has been tested and found to comply with the  
limits for a Class B device, pursuant to Part 15 of the FCC Rules.  
These limits are designed to provide reasonable protection  
against harmful interference in a residential installation. This  
equipment generates, uses, and can radiate radio frequency  
energy, and, if not installed and used in accordance with in-  
structions, may cause harmful interference with radio commu-  
nications. However, there is no guarantee that radio interfer-  
ence will not occur in particular installation. If this equipment  
does cause harmful interference to radio or television recep-  
tion, which can be determined by turning the equipment off and  
on, the user is encouraged to consult the dealer or an experi-  
enced radio/TV technician for help.  
Carefully read this manual before using the unit. If you en-  
counter any problems that are not covered in this manual,  
please consult the dealer where you purchased the unit or  
the dealer nearest to you.  
• Avoid installing the unit where it would be subject to high tem-  
peratures, such as in direct sunlight or a hot air stream from  
the heater, or where it would be subject to dust, dirt, or exces-  
sive vibration.  
Do not turn on the unit if the temperature inside the car is  
very high. Always cool down the unit before usage. Parking  
your car in direct sunlight will result in a temperature rise.  
If the unit does not turn on, check the connections first. Then  
check whether the fuse at the back of the unit is blown.  
This unit has been designed specifically for playback of com-

octagonal discs, etc. The player could be dameged.  
Features  
Handling Compact Discs  
• Detachable front panel  
• Built-in power amplifier  
(max. output : 52.5W × 4ch)  
Be careful when removing a compact disc after the playback  
is completed because the disc may be extremely hot.  
Do not expose compact discs to direct sunlight or any direct  
heat source.  
Check all compact discs before playing, and discard cracked,  
scratched or warped discs.  
Wipe dirty or damp discs outward from the center with a soft  
cloth.  
Do not use any solvent such as commercially available clean-  
ers, antistatic spray, or thinner to clean the compact discs.  
Security  
• Digital 12-hour quartz clock  
• FM/AM PLL synthesizer tuner  
• 30 Station preset memory

Precautions  
Be sure to remove/detach the front panel before you start  
installing the unit.  
Choose the mounting location carefully so that the unit will  
not interfere with the normal driving operations of the driver.  
Use only the supplied mounting hardware for a safe and se-  
cure installation.  
2. Select and bend the appropriate tabs to hold the sleeve  
firmly in place.  
Handle the sleeve carefully to avoid injuring your fingers.  
When mounting the unit in a car, keep the unit as level as  
possible. If the unit must be mounted at an angle, due to the  
design of the vehicle, make sure that the unit does not tilt  
upward by more than 30°.  
The distance to the fire wall varies due to the  
type of the car. Be sure to secure the unit by  
properly inserting the bushing.  
Mounting Strap Use  
*
Caution  
Insufficient fastening of the screw may cause  
some CDs to skip.  
3. Attaching the Mounting Strap to the underside of the dash  
board, using screw.  
Attach the back of the unit to the Mounting Strap using the  
support stem bolt and hardware.  
* Warning  
Failure to properly install the Mounting Strap or rear support  
Bushing is a major cause of CD skipping. Without these secur-  
ing devices, the chassis of the CD receiver is able to move up &  
down whenever the road has imperfections and CD skipping  
results.

Note  
Some Japanese/Asian vehicles such as TOYOTA & NISSAN do  
not require use of the sleeve and trim ring assembly.  
To secure the replacement radio use the O.E.M. brackets and  
mounting screws. These brackets will align with the threaded  
screw holes found on each side of the new radio.
