s on installing two-w ayradios &
WARNING Risk of accident due to
improper workon two-w ayradios
The elect romagnetic radiation from two-w ay
ra dios can inter fere with the on-board elec‐
tronics if RF transmit ters are manipulated or
re trofitted inco rrectly.
This could jeopardize the operating saf ety of
th eve hicle. #
You should ha veall workon electrical
and electronic components car ried out
at a qualified specialist workshop. &
WARNING Risk of accident from incor‐
re ct ope ration of two-w ayradios
If yo u operate two- wayra dios incor rectly in
th eve hicle, the electromagnetic radiation
could inter fere with the on-board electronics,
e.g.:
R ifth e two-w ayradio is not connec tedto
an exterior antenna
R ifth eex terior antenna is not cor rectly
mounted or is not of low reflection
This could jeopardies the operating saf ety of
th eve hicle. #
Have the lo w-reflection exterior
antenna ins talled at a qualified special‐
ist workshop. #
When operating two-w ayradios in the
ve hicle, alw ays connect them tothe
lo w- reflection exterior antenna. *

mit due tofailure tocomply wi th the
instructions for ins tallation and use The operating permit may be in

two-w ayradios are not obser ved. #
Only use appr oved frequency bands. #

Rear fende rs
On there ar fende rs, it is recommended that you
ins tallth e antenna on the side of theve hicle
closest tothe center of thero ad.
Use Tech nical Specification ISO/TS 21609 (Road
Ve hicles – "EMCs for ins tallation of af term arket
ra dio frequency transmitting equipment") when re
trofitting two-w ayradios. Comply with the
legal requirements for de tach able parts.
If yo ur vehicle has ins talling for two-w ayradio
equipment, use the po wer supp lyand antenna
connec tors prov ided in the pre-ins tallation.
Obser vethe manufacturer's supplements when
ins talling.
