For example:
Rad iverted route
Rthe road layout or the direction of aone-way
street has been changed
For this reason, you must alwayso bserve road

exposure limits set forth for uncontrolled equip-
ment and meets the FCC radi ofrequency (RF)
Exposure Guidelines in Supplement CtoOET65.

that is deemedtoc omply withoutmaximum
permissive exposure evaluation (MPE). How-
ever, it is recommended to insta
ll it at
adistance
of at least 8inches (approx. 20 cm) betwee nthe
radiation source and aperson's body (not
including limbss uch as hands, wrists, feet and

GWARNING
Modifications to electronic components, their software as wel laswiring can impair their
function and/or the function of other net-
worked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as inten-
ded and/or jeopardize the operating safety of
the vehicle .There is an increase drisk of an
accident and injury.
Never tamper with the wiring as wel laselec-
tronic components or their software .You
shoul dhave all work to electricala nd elec-
tronic equipment carried out at aqualified
specialist workshop.
If you make any changes to the vehicle elec-
tronics, the general operating permit is ren-
dered invalid.
