Retrofitting of two-way radios and
mobile phones (RF transmitters)
Use the Technical Specification
ISO/TS 21609 28
implementation regulation
when retrofitting RF (radio frequency) trans-
mitters.
If your vehicle has fittings for two-way radio
equipment (e.g. taxis, hire cars or official vehi-
cles), use the power supply or aerial connec-
tions intended for use with the basic wiring.
Be sure to observe the manufacturer's addi-
tional instructions when installing the fittings.
! The Mercedes-Benz warranty does not
cove rconsequential damage resulting from
improper installation.
To ensure proper installation, Mercedes-
Benz recommends having this work done
at a Mercedes-Benz Service Centre or at
another qualified specialist workshop.
Transmission output The transmission output at the aerial base
must not exceed the maximum values below.
Waveband Maximum trans-
mission output
(PEAK)
Short wave (f <
54 MHz) 30 W
4 m waveband 15 W
2 m waveband 25 W
Trunked radio/Tetra 15 W
70 cm waveband 15 W
GSM 900/AMPS 10 W
GSM 1800 10 W
UMTS 10 W Aerial positions
The following aerial positions may be used if
RF transmitters have been properly installed:
Aerial positions

Rear mudguard (recommended installa-
tion position: on the side which faces the
centre of the road) G
Risk of accident
Incorrect retrofitting of RF transmitters can
cause the vehicle electronics to malfunction,
impair the vehicle's operating safety and,
thus, also impair your own safety.
To ensure proper installation, Mercedes-Benz
recommends having this work done at a
Mercedes-Benz Service Centre or at another
qualified specialist workshop. G
Risk of injury
Improper installation of RF transmitters can
lead to increased electromagnetic radiation in
the vehicle interior .Using an exterior aerial
takes into account current scientific discus-
sions relating to the possible health hazards
that may result from electromagnetic fields.
To ensure proper installation, Mercedes-Benz
recommends having this work done at a
Mercedes-Benz Service Centre or at another
qualified specialist workshop.
Deviations with respect to aerial locations,
output and frequencies must be approved by
Mercedes-Benz.

Other aerial positions
There is no restriction for aerial positions in
the outer area of the vehicle for these wave-
bands: trunked radio/Tetra, 70 cm wave-
band, GSM 900/AMPS, GSM 1800 and
UMTS.
Legal provisions for fittings must be
observed.
RF transmitters with a maximum transmis-
sion output of 100 mW (PEAK) may be used
in the vehicle without restrictions.
! The operating permit may be invalidated
if the instructions for installation and use of
RF transmitters are not observed, e.g.
approved wavebands, maximum output
and aerial positions on the vehicle. Vehicle identification plates
