CLEAN: If this message appears on the display, the cassette tape player needs to be cleaned. It will still play tapes, but you should clean it as soon as possible to prevent damage to the tapes and player. See Care of Your Cassette Tape Player on page 3-125. If any error occurs repeatedly or if an error can't be corrected, contact your dealer. Playing a Compact Disc Insert a disc partway into the slot, label side up. The player will pull it in and the disc should begin playing. The display will show the CD symbol. If you want to insert a compact disc with the ignition off, first press DISP or the eject symbol. If playing a CD-R the sound quality may 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. You may experience an increase in skipping, difficulty in finding tracks and/or difficulty in loading and ejecting. If these problems occur try a known good CD. Do not add paper labels to discs, they could get caught in the CD player. Do not play 3 inch discs without a standard adapter disc. If an error appears on the display, see "Compact Disc Messages" later in this section. 1 PREV (Previous): Press this pushbutton to go to the previous track if the current track has been playing for less than eight seconds. If pressed when the current track has been playing for more than eight seconds, it will go to the beginning of the current track. TRACK and the track number will appear on the display. If you hold this pushbutton or press it more than once, the player will continue moving back through the disc. CD Adapter Kits It is possible to use a portable CD player adapter kit with your cassette tape player after activating the bypass feature on your tape player. To activate the bypass feature, perform the following steps: 1. Turn the ignition on. 2. Turn the radio off. 3. Press and hold the TAPE DISC button for five seconds. The radio will display READY and the tape symbol on the display will flash, indicating the feature is active. 4. Insert the adapter into the cassette tape slot. It will power up the radio and begin playing. The override feature will remain active until the eject symbol is pressed. 3-96
