Notes on installing two-wayradios
\nWARNINGRisk of accident duetoimproperworkon two-wayradios
The electromagneticradiation from two-wayradios can interferewiththe on-board elec‐tronics if RF transmittersare manipulated orretrofitted incorrectly.
This could jeopardizethe operating safety ofthevehicle.
You should haveallworkon electricaland electronic components carried outat aqualified specialistworkshop.
\nWARNINGRisk of accident from incor‐rect operation of two-wayradios
Ifyou operate two-wayradios incorrectly inthevehicle,the electromagneticradiationcould interferewiththe on-board electronics,e.g.:
Rifthe two-wayradio is not connectedtoanexterior antenna
Riftheexterior antenna is not correctlymounted or is not of lowreflection
This could jeopardiesthe operating safety ofthevehicle.
Havethe low-reflectionexteriorantenna installed at aqualified special‐istworkshop.
When operating two-wayradios inthevehicle, always connectthemtothelow-reflectionexterior antenna.
NOTEInvalidation ofthe operating per‐mit duetofailuretocomply with theinstructionsfor installation and use
The operating permit may be invalidated ifthe instructionsfor installation and use oftwo-wayradios are not observed.
Only use approved frequency bands.
Observethe maximum permissible out‐put power inthese frequency bands.
Only use approved antenna positions.

Onvehicles with a panoramic sliding sunroof,installing an antennatothe front orrearroofarea is not permitted.
Ontherearfenders, it isrecommendedthatyouinstallthe antenna onthe side ofthevehicleclosesttothe center oftheroad.
UseTechnical Specification ISO/TS21609 (RoadVehicles – "EMCsfor installation of aftermarketradio frequency transmitting equipment") whenretrofitting two-wayradios. Comply withthelegalrequirementsfor detachable parts.
Ifyourvehicle has installationsfor two-wayradioequipment, usethe power supplyand antennaconnectorsprovided inthe pre-installation. Besuretoobservethe manufacturer's supplementswhen installing.
