telephone manufacturer before putting a
telephone into operation.
f Please observe the applicable national regula-
tions regarding telephone calls during driving.

f For reasons of road safety, only telephone

f
To prevent any possible risk to health:
Use telephones or 2-way radios with integral
radio antennas in the vehicle only if an external
antenna is connected.
Installation of mobile communications systems
(car telephone, 2-way radio, etc.) requires
approval and should be performed only according
to Porsche installation specifications in a
specialist workshop.
The transmission power must not exceed
10 W.
The devices must possess a type approval for
your vehicle and have an “e” symbol .
If you should require equipment with transmission
power values greater than 10 W, please consult a
qualified specialist workshop for this purpose. The
workshop will be familiar with the technical require-
ments for installing devices of this kind.
Incorrectly installed equipment or antennas as well
as telephones and 2-way radios without external
antenna may interfere with the vehicle electronics
as a result of radio transmission. Therefore, use
telephones or 2-way radios only with connected
external antenna.
Hands-free microphone
Hands-free microphones installed at the factory
must be adapted to the type of telephone in use.
Your Porsche partner will be pleased to advise
you.
Reception quality
The reception quality of your telephone changes
continuously while you drive.
Interference from buildings, terrain and the
weather is unavoidable.
Comprehensibility can be adversely affected by
external noise (e.g. engine and wind noise), partic-
ularly when hands-free equipment is used.
