Two-way radios and fa xequipment used with-
out low-reflection exterior aerials can inter-
fere with the vehicle's electronic sand thereby
jeopardise the operatin gsafety of the vehicle

WARNING
Excessiv elevels of electromagnetic radiation
may cause damage to your health and the
health of others. Using an exterior aerial takes

the vehicle
R mutual influences between the vehicle
electronic sand mobile phones are mini-
mised
An exterior aerial has the following advan-
tages:
R it conducts the electromagnetic fields gen-
erated by awireless device to the exterior.
R the field strengt hinthe vehicle interior is
lower than in avehicle that does not have
an exterior aerial.
