Notes on installing two-wayradios
&WARNINGRisk 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.
&WARNINGRisk 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.
