Use Tech nical Specification ISO/TS 21609 (Road
Ve hicles – "EMC guidelines for ins tallation of
af te rm arke tra dio frequency transmitting equip‐
ment") when retrofitting two-w ayradios. Comply
with the legal requ irements for de tachable parts.
If yo ur vehicle has ins tallations for two-w ayradio
equipment, use the po wer supply or antenna
connections intended for use with the basic wir‐
ing. Obser vethe manufacturer's supplements
when ins talling.
