Cassettes are subject to wear and the sound quality may degrade over time. Always make sure the cassette tape is in good condition before the tape player is serviced. Check occasionally to make sure the mast is still tightened to the fender. If tightening is required, tighten by hand, then with a wrench one quarter turn. Care of Your CDs Handle CDs carefully. Store them in their original cases or other protective cases and away from direct sunlight and dust. If the surface of a CD is soiled, dampen a clean, soft cloth in a mild, neutral detergent solution and clean it, wiping from the center to the edge. Be sure never to touch the side without writing when handling CDs. Pick up CDs by grasping the outer edges or the edge of the hole and the outer edge. Chime Level Adjustment The radio is the vehicle chime producer. The chime is produced from the driver's side front door speakers. To change the volume level, press and hold pushbutton 6 with the ignition on and the radio power off. The chime volume level will change from the normal level to loud, and LOUD will appear on the radio display. To change back to the default or normal setting, press and hold pushbutton 6 again. The chime level will change from the loud level to normal, and NORMAL will appear on the radio display. Each time the chime volume is changed, three chimes will sound to indicate the change. Removing the radio and not replacing it with a factory radio or chime module will disable vehicle chimes. Care of Your CD Player The use of CD lens cleaners for CD players is not advised, due to the risk of contaminating the lens of the CD optics with lubricants internal to the CD mechanism. Fixed Mast Antenna The fixed mast antenna can withstand most car washes without being damaged. If the mast should ever become slightly bent, straighten it out by hand. If the mast is badly bent, replace it. 3-74
