FM
reception

A vehicle isnot anideal place tolisten toaradio.
Because thevehicle moves, reception conditions
are constantly changing.
Buildings, terrain,signaldistance andnoise from
other vehicles areallworking againstgoodrecep-
tion. Some conditions ofFM may appear tobe prob-
lems when theyarenot.
The following characteristics arecompletely nor-
mal foragiven reception area,andthey donot In-
dicate anyproblem withtheradio itself.

Note
Electronic accessories shouldonlybeinstalled by
your authorized Porschedealer.
Equipment whichhasnotbeen tested andap-
proved byPorsche mayimpair radioreception.
Fading
anddrifting

FM range islimited toabout 25miles (40km),
except forsome highpower stations.
If avehicle ismoving awayfromthedesired sta-
tion's transmitter, thesignal willtend tofade and!
or drift. Thiscondition ismore prevalent withFM
than AM,andisoften accompanied bydistortion.
Fading anddrifting canbeminimized toacertain
degree bycareful attention tofine tuning orselec-
tion ofastronger signal.

Static andfluttering

When theline-{)f-sight linkbetween atransmitter
and vehicle isblocked bylarge buildings ormoun-
tains theradio sound maybeaccompanied with
stati~ orfluttering becauseofthe characteristic of

FM.

In asimilar effect,afluttering noiseissometimes
heard whendriving alongatree-lined road.
This static andfluttering canbereduced byadjust-
ing the tone control forgreater bassresponse un-
til the disturbance haspassed.
Multipath

Because ofthe reflecting characteristics ofFM,
direct andreflected signalsmayreach theanten-
na atthe same time(multipath) andcancel each
other out.
As avehicle movesthrough theseelectronic dead
spots, thelistener mayhear amomentary flutter
or loss ofreception.

Station swapping

When twoFMstations areclose toeach other, and
an electronic deadspot, suchasstatic ormulti-
path area, interrupts theoriginal signal,some-
times thestronger secondsignalwillbeselected
automatically untiltheoriginal onereturns.
This swapping canalso occur asyou drive away
from theselected stationandapproach another
station ofastronger signal.
