WARNING
The electromagnetic radiation from two-way
radios can interfere with the vehicle electron-
ics if two-way radios are manipulated or ret-
rofitted 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 quali-
fied 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 moun-
ted 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 discussions relating
to the possible health hazards that may result
from electromagnetic fields.
The following antenna positions may be used for
the correct installation of two-way radios: Approved antenna positions
0043
Rear roof area
0044 Rear fender
i 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 Technical Specification ISO/TS 21609
(Road Vehicles – "EMC guidelines for installa-
tion of aftermarket radio frequency transmitting
equipment") when installing wireless devices.
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 wir-
ing. Be sure to observe the manufacturer's Sup- plement when installing.
Deviations with respect to frequency bands,
maximum transmission outputs or antenna
positions must be approved by Mercedes-Benz. 382

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 Two-way radios with a maximum transmission
output of up to 100 mW
R Two-way radios 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 2G/3G/4G Identification plates
