The electromagneti c radiation from modifie d
or incorrectl y retrofitte d RF-transmitters can
interfere wit h th e vehicl e electronics . This can
compromise th e operational safet y of th e
vehicle. Ther e is a ris k of an accident.
You should hav e all wor k to electrical and
electronic equipmen t carried out at a qualified
specialist workshop.

The electromagneti c radiation from incor-
rectl y operate d RF transmitters can interfere
wit h th e vehicl e electronics , for example:R
if th e RF transmitte r is no t connecte d wit h
an exterio r antennaR
th e exterio r antenna has been installed
incorrectl y or is no t a low-reflection typ e
This can compromise th e operational safet y
of th e vehicle. Ther e is a ris k of an accident.
Hav e th e low-reflection exterio r antenna
mounte d at a qualified specialist workshop.
When operating RF transmitters in th e vehi-
cle , always connec t them wit h th e low-reflec -
tion exterio r antenna.
! The operating permit may be invalidated if
th e instruction s for installation and use of RF
transmitters are no t observed. In particular, th e followin g condition s must be
complied with: R
only approve d wavebands may be used. R
observ e th e maximum permissible output
in these wavebands. R
only approve d antenna position s may be
used.
Excessiv e levels of electromagneti c radiation
may caus e damag e to your healt h and th e healt h
of others. Using an exterio r antenna takes int o
accoun t curren t scientific discussion s relating
to th e possible healt h hazards that may result
from electro magneti c fi
elds.
The followin g antenna position s may be used if
RF transmitters hav e been properly installed:

Rear roo f areaD
Rear fender
i On th e rear fenders, it is recommended to
position th e antenna on th e side of th e vehicl e
closes t to th e center of th e road .
Use th e Technical Specification ISO/TS 2160 9
when retrofitting RF transmitters (Road Vehicles
- EM C guidelines for installation of aftermarket
radi o frequency transmitting equipment) .
Observ e th e legal requirements for accessory
parts.
If your vehicl e has installation s for two-way radi o
equipment, use th e power suppl y or antenna
connection s intended for use wit h th e basic wir-
ing . Be sur e to observ e th e manufacturer' s Sup -
plemen t when installing.
Deviation s wit h respec t to frequency bands,
maximum transmission output s or antenna
position s must be approve d by Mercedes-Benz.376

Technical data

The maximum transmission output (PEAK) at the
base of the antenna must not exceed the fol-
lowing values:
Frequency band Maximum
transmission
output
Short wave
3 - 54 MHz 100 W
4 m waveband
74 - 88 MHz 30 W
2 m waveband
144 - 174 MHz 50 W
Trunked radio system/
Tetra
380 - 460 MHz 10 W
70 cm waveband
400 - 460 MHz 35 W
Mobile communications
(2G/3G/4G) 10 W
The following can be used in the vehicle without
restrictions: R
RF transmitters with a maximum transmis-
sion output of up to 100 mW R
RF transmitters with transmitter frequencies
in the 380 - 410 MHz waveband and a maxi-
mum transmission output of up to 2 W
(trunked radio/Tetra) R
Mobile phones (2G/3G/4G)
There are no restrictions when positioning the
antenna on the outside of the vehicle for the
following wavebands: R
Trunked radio system/Tetra R
70 cm waveband R
