Remote Cassette Tape Player (If Equipped) A lighted tape symbol shows when a cassette tape is in the player. A lighted arrow will also appear and show the direction of play when a tape is active. The player automatically senses if the cassette tape is metal or CrO2 and adjusts for best playback sound. Anytime a cassette tape is inserted, the top side is selected for play first. If you have an AM-FM Stereo Audio Compact Disc Automatic Tone Control System that includes a remote cassette player, the cassette player is located in the center of the instrument panel. Your 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. To load a cassette tape with the ignition off, first press EJECT on the remote player. Then, insert the cassette tape. The tape will play if the ignition is on but the radio is off. Once the tape is playing, use the control knobs for VOL, AUTO TONE, BAL, FADE, BASS and TREB just as you do for the radio. PREV (1): Press PREV or the SEEK left arrow (in the opposite direction that the lighted tape direction arrow points) to search for the previous selection. A minimum three-second blank gap is needed for the player to stop at the beginning of the selection. The tape direction arrow will blink during the SEEK operation and the sound is muted in this mode. NEXT (3): Press NEXT or the SEEK right arrow (in the direction that the lighted tape direction arrow points) to search for the next selection. The tape direction arrow will blink during SEEK operation and the sound is muted in this mode. REV (4): Press this button to rapidly reverse the tape. The tape will rapidly reverse to the beginning of the cassette reel or until you press REV again. The radio plays the last selected station during REV. 3-29
