SAFETY INFORMATION  
When Driving  
Disc Maintenance  
Keep the volume level Iow enough to be aware of the road and traffic conditions.  
A dirty or defective disc may cause sound dropouts while playing. Before playing, wipe  
the disc using a clean cloth, working from the center hole towards the outside edge.  
Never use benzene, thinners, cleaning fluids, anti-static liquids or any other solvent.  
When Washing your Vehicle  
Do not expose the product to water or excessive moisture. Moisture can cause electrical  
shorts, fire or other damage.  
When Parked  
Parking in direct sunlight can produce very high temperatures inside your vehicle. Give the  
interior a chance to cool down before starting playback.  
Use the Proper Power Supply  
This product is designed to operate with a 12 volt DC negative ground battery system.  
Protect the Disc Mechanism

side up.  
Do not bend.  
Wipe clean from  
the center to the  
edge.  
Never touch  
the under side  
of the disc.  
Avoid inserting any foreign objects into the disc slot. Misuse may cause malfunction or  
permanent damage due to the precise mechanism of this unit.  
CAUTION:  
Be sure to use only round CDs for this unit and do not use any special shape CDs. Use of  
special shape CDs may cause the unit to malfunction.  
Do not stick paper or tape on the disc. Do not use CDs with labels or stickers attached or  
that have sticky residue from removed stickers.  
THIS MOBILE CD PLAYER IS A CLASS I LASER PRODUCT. THIS UNIT USES A VISIBLE/  
INVISIBLE LASER BEAM WHICH COULD CAUSE HAZARDOUS RADIATION IF EXPOSED  
DIRECTLY. BE SURE TO OPERATE THE MOBILE CD PLAYER AS INSTRUCTED.  
USE OF CONTROLS OR ADJUSTMENTS, OR PERFORMANCE OR PROCEDURES  
OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION  
EXPOSURE.  
Do not expose discs to direct sunlight or heat sources.  
NOTE: A disc may become scratched (although not enough to make it unusable)  
depending on how you handle it and other conditions in the usage environment. These  
scratches are not an indication of a problem with the player.  
DO NOT OPEN COVERS AND DO NOT REPAIR BY YOURSELF. PLEASE REFER  
SERVICING TO A QUALIFIED TECHNICIAN.  
WARNING:  
TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS  
EQUIPMENT TO RAIN OR MOISTURE.  
TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK AND ANNOYING  
INTERFERENCE, USE ONLY THE RECOMMENDED ACCESSORIES.  
DISC NOTES  
Depending on the recording status, conditions of the disc, and the equipment used for  
recording, some CD-Rs/CD-RWs may not play on this unit. For more reliable playback, please  
adhere to the following recommendations:  
Use CD-RWs with speed 1x to 4x and write with speed 1x to 2x.  
Use CD-Rs with speed 1x to 8x and write with speed 1x to 2x.  
Do not play a CD-RW which has been written more than 5 times.  
NOTE: CD-R and CD-RW discs will not play unless the recording session is closed and  
the CD is finalized.

INSTALLATION  
to a secure part of the dashboard, either above or below the radio using the screw and  
flange nut provided. Bend the strap to position it as necessary.  
Before You Begin  
1. Disconnect Battery  
Before you begin, always disconnect the battery negative terminal.  
2. Remove Transport Screws  
CAUTION: The rear of the radio must be supported with either the perforated strap or  
the rubber mounting bushing to prevent damage to the dashboard from the weight of  
the radio or improper operation due to vibration.  
Important Notes  
Before final installation, test the wiring connections to make sure the unit is connected  
properly and the system works.  
Use only the parts included with the unit to ensure proper installation. The use of  
unauthorized parts can cause malfunctions.  
Consult with your nearest dealer if installation requires the drilling of holes or other  
modifications to your vehicle.  
Install the unit where it does not interfere with driving and cannot injure passengers if  
there is a sudden or emergency stop.  
If the installation angle exceeds 30º from horizontal, the unit may not give optimum  
performance.  
Avoid installing the unit where it will be subject to high temperatures from direct sunlight,  
hot air, or from a heater, or where it would be subject to excessive dust, dirt or vibration.

This unit is designed for installation in vehicle cabs with an existing 1-DIN radio opening. In  
many cases, a special installation kit will be required to mount the radio to the dashboard.  
These kits are available at electronics supply stores and car stereo specialty shops. Always  
check the kit application before purchasing to make sure the kit works with your vehicle.

Kit Installation  
1. If your radio requires the use of an installation kit to mount this radio, follow the instruc-  
tions included in the kit to attach the radio to the mounting plate supplied with the kit.  
2. Wire and test the radio as described.  
3. Install the radio/mounting plate assembly to the sub-dash according to the instructions of  
the installation kit.  
keys (supplied) to disengage it.  
2. Check the dashboard opening size by sliding the mounting sleeve into it. If the opening is  
not large enough, carefully cut or file as necessary until the sleeve slides easily into the  
opening. Do not force the sleeve into the opening or cause it to bend or bow. Check that  
there will be sufficient space behind the dashboard for the radio chassis. Connect wires  
prior to actually installing the sleeve. Pigtail wiring should take place after hole size is  
confirmed. Mount sleeve after wiring.  
4. Attach the support strap to the radio and dashboard as described above.  
5. Replace the dashboard trim panel.  
3. Follow the wiring diagram carefully and make certain all connections of the wiring harness  
are properly secured and insulated to insure proper operation of this unit. After completing  
the wiring connections, turn the unit on to confirm operation (ignition switch must be “on”).  
If unit does not operate, recheck all wiring until the problem is corrected. Once proper  
operation is achieved, turn off ignition switch and proceed with final mounting of the  
chassis.  
4. Locate the series of bend tabs along the top, bottom, and sides of the mounting sleeve.  
With the sleeve fully inserted into the dash opening, bend tabs outward so that the sleeve  
is firmly secured to the dashboard.

CARE AND MAINTENANCE  
TROUBLESHOOTING  
Keep the product dry. If it does get wet, wipe it dry immediately. Liquids might contain  
minerals that can corrode the electronic circuits.  
Symptom  
Cause  
Solution  
Keep the product away from dust and dirt, which can cause premature wear of parts.  
Handle the product gently and carefully. Dropping it can damage circuit boards and  
cases, and can cause the product to work improperly.  
Wipe the product with a dampened cloth occasionally to keep it looking new. Do not use  
harsh chemicals, cleaning solvents, or strong detergents to clean the product.  
Use and store the product only in normal temperature environments. High temperature  
can shorten the life of electronic devices, damage batteries, and distort or melt plastic  
parts.  
No power

The most common source of noise in reception is the ignition system. This is a result of the  
radio being placed too close to the ignition system (engine). This type of noise can be easily  
detected because it will vary in intensity of pitch with the speed of the engine.

dirty or disc is defective  
Clean the disc or try to play a new  
one.  
Condensation  
Leave the player off for an hour or  
so, then try again.  
Usually, the ignition noise can be suppressed considerably by using a radio suppression type  
high voltage ignition wire and suppressor resistor in the ignition system. (Most vehicles employ  
this wire and resistor but it may be necessary to check them for correct operation.) Another  
method of suppression is the use of additional noise suppressors. These can be obtained from  
most professional mobile electronics retailers.

Interference  
Radio reception in a moving environment is very different from reception in a stationary  
environment (home). It is very important to understand the difference.

Press the RESET button.  
AM reception will deteriorate when passing under a bridge or when passing under high voltage  
lines. Although AM is subject to environmental noise, it has the ability to be received at great  
distance. This is because broadcasting signals follow the curvature of the earth and are  
reflected back by the upper atmosphere.
