Fading and drifting
FM range is limited to about 25 miles (40 km), except for some high power stations.
If a vehicle is moving away from the desired station's transmitter, the signal will tend to fade and/or drift. This condition is more prevalent with FM than AM, and is often accompanied by distortion.
Fading and drifting can be minimized to a certain degree by careful attention to fine tuning or selection of a stronger signal.
Static and fluttering
When the line-of-sight link between a transmitter and vehicle is blocked by large buildings or mountains, the radio sound may be accompanied with static or fluttering because of the characteristic of FM.
In a similar effect, a fluttering noise is sometimes heard when driving along a tree-lined road.
This static and fluttering can be reduced by adjusting the tone control for greater bass response until the disturbance has passed.
Because of the reflecting characteristics of FM, direct and reflected signals may reach the antenna at the same time (multipath) and cancel each other out. As a vehicle moves through these electronic dead spots, the listener may hear a momentary flutter or loss of reception.
When two FM stations are close to each other, and an electronic dead spot, such as static or multipath area, interrupts the original signal, sometimes the stronger second signal will be selected automatically until the original one returns. This swapping can also occur as you drive away from the selected station and approach another station of a stronger signal.
Compact disk player
To avoid damage to compact disk player and disks.
Use only compact disks labeled as shown, having no dirt, damage or warpage.
Never attempt to disassemble or oil any part of the player unit. Do not insert any object other than a disk into the slot. Remember there are no user-serviceable parts inside the compact disk player.
Do not allow the disk to sustain any fingerprints, scrapes or stickers on the surfaces. This may cause poor sound quality. Hold the disk only on the edge or center hole.
When not in use, take the disk out of the player, put the disk back into its case and store it away from dust, heat, damp and direct sunlight.
Leaving the disk on the dashboard in the sun can damage the disk.
If the disk gets dirty, clean the disk by wiping the surfaces from the center to the outside in a radial direction with a soft cloth.
Do not use a conventional record cleaner or anti-static record preservative.
Disk cleaners are available in audio stores.
Car Telephone and Aftermarket Alarms Important legal and safety information regarding the use of cellular telephones
Some jurisdictions may prohibit the use of cellular telephones while driving a vehicle. Check the laws and regulations on the use of cellular telephones in the areas where you drive.
Cell Phone Use
Looking away from the road or turning your attention away from your driving to operate a cell phone will sooner or later cause an accident.
Do not attempt to operate a hand-held cell phone while you are driving. Safety is more important than a phone call.
Learn to operate the hands-free phone, if it is available, before you start driving. Then make use of the hands-free phone at all times.
