The radio will only seek and scan stations with a strong signal that are in the selected band.

Setting Preset Stations

Up to 18 stations (six FM1, six FM2, and six AM), can be programmed on the six numbered pushbuttons, by performing the following steps:

  1. Turn the radio on.

Setting the Tone (Bass/Treble)

BASS/TREB (Treble): Press and release this knob until BASS or TREB appears on the display. Turn the knob to increase or to decrease. The display will show the bass or the treble level. If a station is weak or noisy, decrease the treble.

Turn the knob to move the sound toward the front or the rear speakers.

Playing a Cassette Tape

The tape player is built to work best with tapes that are up to 30 to 45 minutes long on each side. Tapes longer than that are so thin they may not work well in this player. The longer side with the tape visible should face to the right. If you hear nothing or hear a garbled sound, the tape may not be in squarely. Press EJ to remove the tape and start over.

If the ignition and radio are off, press the eject button or the RCL knob to insert and to begin play of a tape. If the ignition is on and the radio is off, the tape can be inserted and will begin playing.

While the tape is playing, use the VOL, BASS/TREB/FADE/BAL, and AUTO TONE controls just as you do for the radio. The tape symbol will appear on the display and an arrow showing which side of the tape is playing.

Cassette tape adapter kits for portable CD players will work in the cassette tape player. See "CD Adapter Kits" later for more information.

    • The tape is tight and the player cannot turn the tape hubs. Remove the tape. Hold the tape with the open end down and try to turn the right hub counterclockwise with a pencil. Turn the tape over and repeat. If the hubs do not turn easily, the tape may be damaged and should not be used in the player. Try a new tape to make sure the player is working properly.
    • The tape is broken. Try a new tape.
    • The tape is wrapped around the tape head. Attempt to get the cassette out. Try a new tape.
CLEAN: If this message appears on the display, the cassette tape player needs to be cleaned. It will still play tapes, but it should be cleaned as soon as possible to prevent damage to the tapes and player. See Care of the Cassette Tape Player . If the cassette tape is not playing correctly, for any other reason, try a known good cassette. If any error occurs repeatedly or if an error cannot be corrected, contact your GM dealer. If the radio displays an error message, write it down and provide it to your GM dealer when reporting the problem.

CD Adapter Kits

It is possible to use a portable CD player adapter kit with the cassette tape player. Insert the adapter as you would insert a normal tape and the adapter should begin playing. The display and radio buttons will function the same.

If the adapter cassette will not play, press the SIDE pushbutton to reverse the adapter. If the adapter still will not play, refer to the directions that came with the adapter.

Playing the Single CD Player

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.

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. There may be an increase in skipping, difficulty in finding tracks, and/or difficulty in loading and ejecting. If these problems occur try a known good CD.
