Troubleshooting

No power.

Vehicle ignition switch is not on. If the power supply is connected to the 

vehicle accessory circuits but the 
engine is not turned on, switch the 
ignition key to “ACC”.

The fuse is blown.

Replace the fuse.

Disc cannot be loaded 
or ejected.

There is a disc already inside 
the unit.

Remove the current disc and insert the 
new one.

Inserting disc in wrong direction. Insert disc with label facing up.
Disc is defective or dirty.

Clean disc or try playing another one.

Excessive temperature in 
vehicle.

Cool vehicle to a normal temperature.

Condensation has collected.

Turn player off for an hour, then try 
again.

No sound.

Volume turned down too low.

Adjust volume until sound is heard.

Wiring not connected properly.

Check wiring connections.

Sound skips or sound 
quality is poor.

degrees.

Adjust the installation angle to less 
than 30 degrees.

Disc is defective or dirty.

Clean disc or try playing another one.

Cassette is defective.

Try playing another cassette.

Operation keys do not 
work.

Ignition and Interference Noise

The most common source of noise in reception is the ignition system, due to the fact that the 
radio is placed relatively 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.Generally, the 
ignition noise can be suppressed considerably by using a radio suppression high-voltage 
ignition wire and suppressor resistor in the ignition system. Additional noise suppressors may 
also be used and can be obtained from most CB/amateur radio or electronic supply stores.

Radio reception in a moving environment is very different from stationary reception. For 
example, AM reception will deteriorate when passing through a tunnel or under high-voltage 
lines. Also, noise can be picked up from passing vehicles. Although AM is subject to 
interference, it has the ability to be received at great distances because the broadcasting 
signals follow the curvature of the earth and are reflected back by the upper atmosphere.

Maintenance

The following maintenance tips will extend the life and optimize the performance of the unit.

•

Keep the unit dry. If it is exposed to moisture, wipe it dry immediately. Liquids may contain 
minerals that can corrode the electronic circuits.

•

Keep the unit away from dust and dirt, which can cause premature wear of parts.

•

Handle the unit carefully; dropping it can damage circuit boards and cases, causing the 
product to malfunction.

•

Clean the unit occasionally by wiping it with a damp cloth. Do not use harsh chemicals, 
cleaning solvents or strong detergents to clean the product.

•

Use and store the unit only in mild temperature environments. High temperatures can 
shorten the life of electronic products, damage batteries and distort/melt plastic parts.
