extreme cases this could mean
that
you lose the
type approval
for
your vehicle.
Qualified workshops will be able to inform you
about options for installing and operating radio
transmitters.
Business equipment
Retrofit installation of business or other equip­
ment in the vehicle is permitted, provided the
equipment cannot interfere with the driver's im­
mediate controL of the vehicle. Any such equip­
ment must carry the
CC
mark. Any retrofit equip­
ment that could influence the driver's control of
the vehicLe must have a type approval for road
vehicles and must carry the e mark.
A WARNING
- Loose or incorrectly secured radio equip­
ment could be catapulted through the
vehi­

cle during sudden driving/braking manoeu­
vres or in the event of an accident. This
poses a risk of injury to occupants.
- Always ensure that radio equipment is prop­
erly secured outside the deployment area of
the airbags or stowed safely while the
vehi­

cle is moving.
- Mobile telephones or radio equipment
which are operated inside the vehicle
with­

out
a
correctly installed external aerial can
create excessive magnetic fields that could
cause a health hazard.
© CAUTION
If
you
use radio equipment in the car without
an external aerial, the electromagnetic radia­
tion in the vehicle could exceed the recom­
mended limits. This also applies to external
aerials which have not been correctLy instal­

led.

- Do not operate radio equipment in the
vehi­

cle unless an external aerial is properly
con­

nected.

Please observe the relevant regulations and
follow the instructions in the operating
man­

ual for the radio equipment.
