WARNING
ARNING Risk of accident due to
improper work on two-way radios
If two-way radios are manipulated or retro tted
incorrectly, the electromagnetic radiation from
the two-way radios can interfere with the vehi-
cle electronics and jeopardize the operating
safety of the vehicle.
#
You should have all work on electrical
and electronic components carried out
at a quali ed specialist workshop.

WARNING
ARNING Risk of accident due to
improper operation of two-way radios
If you use two-way radios in the vehicle
improperly, their electromagnetic radiation can
disrupt the vehicle's electronics. This is the
case in the following situations, in particular:
R
The two-way radio is not connected to an
exterior antenna.
R
The exterior antenna is installed incorrectly
or is not a low-re ection antenna.
This could jeopardize the operating safety of
the vehicle.
#
Have the low-re ection exterior antenna
installed at a quali ed specialist work-
shop.
#
When operating two-way radios in the
vehicle, always connect them to the low-
re ection exterior antenna.

TE Invalidation of the operating permit
due to failure to comply with the instruc-
tions for installation and use
The operating permit may be invalidated if the
instructions for installation and use of two-way
radios are not observed.
#
Only use approved frequency bands.
#
Observe the maximum permissible out-
put power in these frequency bands.
#
Only use approved antenna positions.
Use Technical Speci cation ISO/TS 21609 (Road
Vehicles - EMC guidelines for installation of a er-
market radio frequency transmitting equipment)
when retro tting two-way radios. Comply with the
legal requirements for detachable parts.
If your vehicle has installations for two-way radio
equipment, use the power supply or antenna con-
nections intended for use with the installation.
Observe the manufacturer's supplements during
installation.
