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.
Multipath
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.
Station swapping
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.
f
Use only compact disks labeled as shown,
having no dirt, damage or warpage.
f
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.
f
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.
f
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.
f
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.
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.
f
Do not attempt to operate a hand-held cell
phone while you are driving. Safety is more
important than a phone call.

available, before you start driving. Then make
use of the hands-free phone at all times.

accordance with the technical requirements of
Porsche.
The transmission power must not exceed
10 W.

If you should require equipment with transmission
power values greater than 10 W, please consult
your authorized Porsche dealer for this purpose.
They are familiar with the technical requirements
for installing devices of this kind.
The antennas for all radios and telephones with a
transmitting antenna must be externally mounted.
The improper installation of radios or telephones
or use of a radio or telephone with a transmitting
antenna inside the car may cause
the warning
lights to come on.
