Vehicle electronics
Installing two-way radios and mobile
phones (RF transmitters)
G
WARNING
The electromagnetic radiation from two-way
radios can interfere with the vehicle elec-
tronics if two-way radios are manipulated or
retrofitted incorrectly. This could jeopardize
the operating safety of the vehicle. There is
a risk of an accident.
You should have all work on electrical and
electronic components carried out at a
qualified specialist workshop.
G
WARNING
If you incorrectly operate two-way radios in
the vehicle, the electromagnetic radiation
may interfere with the vehicle electronics,
for example if:
R
the two-way radio is not connected to an
exterior antenna
R
the exterior antenna is not correctly
mounted or is not low-reflection
This could jeopardize the operating safety of
the vehicle. There is a risk of an accident.
Have the low-reflection exterior antenna
installed at a qualified specialist workshop.
Always connect two-way radios to the low-
reflection exterior antenna when operating
in the vehicle.
!
The operating permit may be invalidated if
the instructions for installation and use of
two-way radios are not observed.
In particular, the following requirements
must be complied with:
R
only approved wavebands may be used
R
observe the maximum permissible output
in these wavebands
R
only approved antenna positions may be
used
Excessive levels of electromagnetic radiation
may cause damage to your health and the
health of others. Using an exterior antenna
takes into account current scientific discus-
sions relating to the possible health hazards
that may result from electromagnetic fields.
Approved antenna positions
:
Front roof area
;
Rear roof area
=
Rear fender
i
On vehicles with panorama roof with
power tilt/sliding panel, installing an
antenna to the front or rear roof area is not
permitted.
On the rear fenders, it is recommended to
position the antenna on the side of the vehi-
cle closest to the center of the road.
Use the Technical Specification ISO/TS 21609
when retrofitting RF transmitters (Road Vehi-
cles - EMC guidelines for installation of after-
market radio frequency transmitting equip-
ment). Observe the legal requirements for
accessory parts.
If your vehicle has installations for two-way
radio equipment, use the power supply or
antenna connections intended for use with the
basic wiring. Be sure to observe the manufac-
turer's Supplement when installing.
Deviations with respect to frequency bands,
maximum transmission outputs or antenna
positions must be approved by Mercedes-
Benz.
