Retrofitting two-way radios and
mobile phones (RF transmitters)

WARNING
The electromagnetic radiation from modified
or incorrectly retrofitted RF-transmitters can
interfere with the vehicle electronics. This can
compromise the operational safety of the
vehicle. There is a risk of an accident.
You should have all work to electrical and
electronic equipment carried out at a qualified
specialist workshop.
G
WARNING
The electromagnetic radiation from incor-
rectly operated RF transmitters can interfere
with the vehicle electronics, for example:
R
if the RF transmitter is not connected with
an exterior antenna
R
the exterior antenna has been installed
incorrectly or is not a low-reflection type
This can compromise the operational safety
of the vehicle. There is a risk of an accident.
Have the low-reflection exterior antenna
mounted at a qualified specialist workshop.
When operating RF transmitters in the vehi-
cle, always connect them with the low-reflec-
tion exterior antenna.
!
The operating permit may be invalidated if
the instructions for installation and use of RF
transmitters are not observed.
In particular, the following conditions must be
complied with:
R
only approved wavebands may be used.
R
compliance with the maximum permissible
output in these wavebands is required.
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 discussions relating
to the possible health hazards
tha
t may result
from electromagnetic fields.
The following antenna positions may be used if
RF transmitters have been properly installed:
Approved antenna positions
:
Front roof area
;
Rear roof area
=
Rear fender
?
Trunk lid
i
When installing an antenna on the front roof
area of vehicles with a sliding sunroof,
observe the sweeping range of the roof.
On the rear fenders, it is recommended to
position the antenna on the side of the vehicle
closest to the center of the road.
Use the Technical Specification ISO/TS 21609
when retrofitting RF transmitters (Road Vehicles
- EMC guidelines for installation of aftermarket
radio frequency transmitting equipment).
Observe the legal requirements for retrofittings.
If your vehicle has installations for two-way radio
equipment, use the power supply or antenna
connections intended for use with the basic wir-
ing. Be sure to observe the manufacturer's addi-
tional instructions when installing.
Deviations with respect to wavebands, maxi-
mum transmission outputs or antenna positions
must be approved by Mercedes-Benz.
