Installing two-way radios and mobile
phones

WARNING
The electromagnetic radiation from two-
way radios can interfere with the vehicle
electronics if they are manipulated or ret-
rofitted incorrectly. This could jeopardise
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.

WARNING
If you operate two-way radios incorrectly
in the vehicle, their electromagnetic radi-
ation can interfere with the vehicle elec-
tronics, for example if:
the two-way radio is not connected to an
R
exterior aerial
the exterior aerial is not correctly moun-
R
ted or is not low-reflection
This could jeopardise the operating safety
of the vehicle. There is a risk of an accident.
Have the low-reflection exterior aerial fit-
ted at a qualified specialist workshop.
When operating two-way radios in the
vehicle, always connect them to the low-
reflection exterior aerial.
!
Have the engine electronics and parts
belonging to it such as control units, sen-
sors, actuating components or electric
cables maintained only at a qualified spe-
cialist workshop. Otherwise, vehicle com-
ponents may wear more quickly and the
vehicle's operating permit may be invali-
dated.
! The operating permit may be invalidated
if the instructions for installation and use
of two-way radios are not observed.

Excessive levels of electromagnetic radia-
tion can cause damage to health. The use of
an exterior aerial takes into consideration
the scientific discussion surrounding the
possible health risk posed by electromag-
netic fields.
The following aerial positions may be used
for the correct installation of two-way
radios:
Front roof area
:
Rear roof area
;
i On vehicles with a folding top, fitting an
aerial to the front roof area is not permit-
ted.
Use Technical Specification ISO/TS 21609
(Road Vehicles – "EMC guidelines for instal-
lation of aftermarket radio frequency trans-
mitting equipment") when retrofitting two-
way radios. Comply with the legal require-
ments for add-on parts.
If your vehicle has fittings for two-way radio
equipment, use the power supply and aerial
connections intended for use in the basic
wiring. Be sure to observe the manufacturer's
additional instructions during installation.
Deviations with respect to wavebands, max-
imum transmission outputs or aerial posi-
tions must be approved by smart.
only approved wavebands may be used
observe the maximum permissible out-
put in these wavebands
only approved aerial positions may be
used
