Risk of injury
Excessive electromagnetic radiation may
also cause damage to your health and the
health of others. Using an exterior aeria l
takes into account current scientific dis-
cussions relating to the possible health haz-
ards that may result from electromagnetic
fields .
For this reason, only have the exterior aeria l
fitted at a qualified specialist worksho p
which has the necessary specialist knowl-
edge and tools to carry out the work
required. Mercedes-Benz recommend s
that you use a Mercedes-Benz Service
Centre for this purpose. In particular, work
relevant to safety or on safety-related sys-
tems must be carried out at a qualifie d
specialist workshop.
i To ensure optimum reception quality for
mobile phones and two-way radios in the
vehicle, and to minimise mutual influences between the vehicle electronics and mobile
phones/two-way radios, Mercedes-Benz
recommends the use of approved exterior
aerials. An attached exterior aerial has the
effect that the electromagnetic fields trans-
mitted by a wireless device are conducted
to the exterior of the vehicle; the field
strength within the vehicle interior is lower
than in a vehicle that does not have an
exterior aerial. Frequency range Maximum trans-

If electrical or electronic equipment
which does not fulfil these conditions is
retrofitted, the vehicle's general operating
permit may be invalidated (EU Directive 95/54/EC – the Automotive EMC Direc-
tive)
