WARNING Risk of accident dueto
improper work on two-way radios
The electromagnetic radiation from two-way
radios can interfere withthe on-boardelec‐
tronics if RF transmitters aremanipulated or
retrofitted incorrectly.
This could jeopardize theoperating safetyof
thevehicle.
#
Youshouldhave all work on electrical
and electronic componentscarried out
at aqualified specialistworkshop.

WARNING Risk of accident from incor‐
rect operationoftwo-way radios
If youoperatetwo-way radios incorrectlyin
thevehicle, theelectromagnetic radiation
could interfere withthe on-boardelectronics,
e.g.:
R
if thetwo-way radio is notconnected to
an exterior antenna
R
if theexteriorantenna is notcorrectly
mounted or is notoflow reflection
This could jeopardies theoperating safetyof
thevehicle.
#
Have thelow-reflection exterior antenna
installed at aqualified specialistwork‐
shop.
#
When operating two-way radios in the
vehicle, alwaysconnectthem to the
low-reflection exterior antenna.

NOTE Invalidation of theoperating per‐
mit due to failuretocomply with the
instructions forinstallation and use
The operatingpermit maybeinvalidated if the
instructions forinstallation and use of two-
wayradios arenot observed.
#
Onlyuse approved frequency bands.
#
Observe themaximum permissible out‐
put powerinthese frequency bands.
#
Onlyuse approved antenna positions.
Use TechnicalSpecification ISO/TS21609 (Road
Vehicles -EMC guidelines forinstallation of after‐
marketradio frequency transmitting equipment)
when retrofitting two-way radios. Comply withthe
legal requirements fordetachable parts.
If your vehicle has installing fortwo-way radio
equipment,use thepower supplyorantenna con‐
nections intended foruse withthe installing.
Observe themanufacturer's supplement during
installation.
