184 UNDERSTANDING YOUR INSTRUMENT PANEL COMPACT DISC MAINTENANCE To keep the compact discs in good condition, take the following precautions: 1. Handle the disc by its edge; avoid touching the surface. 2. If the disc is stained, clean the surface with a soft cloth, wiping from center to edge. 3. Do not apply paper or tape to the disc; avoid scratching the disc. 4. Do not use solvents such as benzene, thinner, cleaners, or antistatic sprays. 5. Store the disc in its case after playing. 6. Do not expose the disc to direct sunlight. 7. Do not store the disc where temperatures may become too high. NOTE: If you experience difficulty in playing a particular disc, it may be damaged, oversized, or have theft protection encoding. Try a known good disc before considering disc player service. RADIO OPERATION AND CELLULAR PHONES Under certain conditions, the operation of a cellular phone in your vehicle can cause erratic or noisy performance from your radio. This condition may be lessened or eliminated by relocating the cellular phone antenna. This condition is not harmful to the radio. If your radio performance does not satisfactorily "clear" by the repositioning of the antenna, it is recommended that the radio volume be turned down or off during cellular phone operation.
