If it is permitted by law to operate communi-
cations equipment whilet

motion, you must only do so if the traffic sit-
uationp ermits.Otherwise, yo ucould be dis-
tracted fro mthe traffi cconditions ,cause an
accident and injure yourself and others.
Two-way radios and fa xequipment used with-
out low-reflection exterior aerials can inter-
fere with the vehicle's electronic sand thereby
jeopardise the operatin gsafety of the vehicle
and your safety. Therefore, you must only use
this equipment if it is correctly connected to
as eparate reflection-free exterior aerial. G
WARNING
Excessiv elevels of electromagnetic radiation
may cause damage to your health and the
health of others. Using an exterior aerial takes
int oa ccoun tcurren tscientific discussions
relatin gtothe possible health risk posed by
electromagnetic fields.
Mercedes-Benz recommends the use of an
approved exterior aerial. This ensures:
R optimal mobile phone reception quality in
the vehicle
R mutual influences between the vehicle
electronic sand mobile phones are mini-
mised
An exterior aerial has the following advan-
tages:
R it conducts the electromagnetic fields gen-
erated by awireless device to the exterior.
R the field strengt hinthe vehicle interior is
lower than in avehicle that does not have
an exterior aerial.
