Note s on installing two-w ayradios
&
WARNING Risk of accident due to
improper workon two-w ayradios
The electro magneticradiation from two-w ay
ra dios can inter fere with the on-board elec‐
tronics if RF transmitte rsare manipulated or
re trofitted inco rrectly.
This could jeopardize the operating saf etyof
th eve hicle.
#Yo u 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-wa yra dios incor rectly in
th eve hicle, the electromagnetic radiation
could inter fere with the on-board electronics,
e.g.:
Rif th e two-w ayradio is not connec tedto
an exterior antenna
Rif th eex terior antenna is not cor rectly
mounted or is not of low reflection
This could jeopardies the operating saf etyof
th eve hicle.
#Ha ve 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.
* NO
TEInva lidation of the operating per‐
mit due tofailure tocomply wi th the
instructions for ins tallation and use
The operating permit may be in validated if
th e instructions for ins tallation and use of
two-w ayradios are not obser ved.
#Only use appr oved frequency bands.
#Obser vethe maximum permissible out‐
put po wer in these frequency bands.
#Only use appr oved antenna positions.

On vehicles with a panoramic sliding sunroof,
ins talling an antenna tothe front or rear roof
area is not permitted. On
there ar fende rs, it is recommended that you
position the antenna on the side of theve hicle
closest tothe center of thero ad.
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 two-w ayradio equipment
ins talled, use the po wer supply or antenna con‐
nections intended for use with the basic wiring.
Be sure toobser vethe manufacturer's supple‐
ments during ins tallation.
