The stored preset stations are deleted if power to the radio is lost, or if the battery is disconnected.

If AUDIO is not pressed, after 10 seconds audio mode times out and returns to NORMAL MODE.

To adjust the balance between the right and the left speakers, press and release the AUDIO button until BALANCE (BL:0) displays. Press either arrow to move the sound toward the right or the left speakers. The FADER adjust becomes disabled when there are only two speakers available in the vehicle.

Playing a CD

Insert a CD partway into the slot, label side up. The player pulls it in and the CD should begin playing.

If the ignition or radio is turned off with the CD in the player, it stays in the player. When the ignition or radio is turned on, the CD starts playing where it stopped, if it was the last selected audio source.

When a CD is inserted, the CD symbol displays. As each new track starts to play, the track number displays.

The CD player can play the smaller 3 inch (8 cm) single CDs with an adapter ring. Full-size CDs and the smaller CDs are loaded in the same manner.

Care of Your CDs

If playing a CD-R, the sound quality can be reduced due to CD-R quality, the method of recording, the quality of the music that has been recorded, and the way the CD-R has been handled. Handle them carefully. Store CD-R(s) in their original cases or other protective cases and away from direct sunlight and dust. The CD player scans the bottom surface of the disc. If the surface of a CD is damaged, such as cracked, broken, or scratched, the CD does not play properly or not at all. Do not touch the bottom side of a CD while handling it; this could damage the surface. Pick up CDs by grasping the outer edges or the edge of the hole and the outer edge.

If the surface of a CD is soiled, take a soft, lint free cloth or dampen a clean, soft cloth in a mild, neutral detergent solution mixed with water, and clean it. Make sure the wiping process starts from the center to the edge.

Care of Your CD Player

Do not add any label to a CD, it could get caught in the CD player. If a CD is recorded on a personal computer and a description label is needed, try labeling the top of the recorded CD with a marking pen.

The use of CD lens cleaners for CDs is not advised, due to the risk of contaminating the lens of the CD optics with lubricants internal to the CD player mechanism.

Notice: If a label is added to a CD, or more than one CD is inserted into the slot at a time, or an attempt is made to play scratched or damaged CDs, the CD player could be damaged. While using the CD player, use only CDs in good condition without any label, load one CD at a time, and keep the CD player and the loading slot free of foreign materials, liquids, and debris.

If an error displays, see "CD Messages" later in this section.

1 RDM (Random): Press to hear the tracks in random, rather than sequential, order. Press again to turn off random play.

(Track Up/Down) : Press and release the up arrow to move to the beginning of the next track. If the CD player is in random mode, it goes to the next randomly selected track. Press and release the down arrow to move to the beginning of the current track. If the button is pressed when the first track is playing, it goes to the last track on the CD. If the CD is in random mode, it goes to the beginning of the current track.

(Fast Forward/Fast Reverse) : Press and hold the up arrow to move forward through the tracks on a CD three times the normal speed for the first three seconds and 30 times thereafter. Press and hold the down arrow to move backward through the CD three times the normal speed for the first three seconds and 30 times normal thereafter.

CD Messages

If the CD comes out, it could be for one of the following reasons:

    • It is very hot. When the temperature returns to normal, the CD should play.
    • You are driving on a very rough road. When the road becomes smoother, the CD should play.
    • The CD is dirty, scratched, wet, or upside down.
    • The air is very humid. If so, wait about an hour and try again.
    • There can have been a problem while burning the CD.
    • The label can be caught in the CD player.

If the CD is not playing correctly, for any other reason, try a known good CD.

If any error occurs repeatedly or if an error cannot be corrected, contact your dealer/retailer. If the radio displays an error message, write it down and provide it to your dealer/retailer when reporting the problem.
