Important safety notes G
WARNING
Observ ethe legal requirements of the country
in whic hyou are curren tlyd riving regarding

cations equipment while the vehicle is in

uation permits. Otherwise, you coul dbedis-
trac tedf rom th etraffic conditions, caus ean

Two-way radios and fax equipment used with-
out low-reflection exterior aerials can inter-
fere with the vehicle's electronics and thereby
jeopardise the operating safety of the vehicle

this equipment if it is correctly connected to
as eparate reflection-free exterior aerial. G
WARNING
Excessive levels of electromagnetic radiation
may cause damage to your health and the
health of others. Usin ganexterior aerial takes

electromagnetic fields. Mercedes-Benz recommends the use of an
approved exterior aerial
.This ensures:
R optimal mobile phone reception quality in
the vehicle
R mutua linfluences between the vehicle
electronics and mobil ephones ar emini-
mised
An exterior aerial has the following advan-
tages:

erated by awireless device to the exterior.
R the field strength in the vehicle interior is
lower than in avehicle that does not have
an exterior aerial.
