If yo u use two- wayra dios in theve hicle
improperly, their electromagnetic radiation
can disrupt theve hicle's electronics. This is
true in thefo llowing situations, in particular:
R The two-w ayradio is not connected toan
ex terior aerial.
R The exterior aerial is fitted inco rrectly or
is not a lo w-reflection aerial. This could jeopardise
the operating saf ety of
th eve hicle. #

when retrofitting two-w ayradios. Comply with the
legal requirements for de tach able parts.
If yo ur vehicle has fittings for two-w ayradio
