Technical data 361

& WARNING Risk of accident from incor‐
rect operation of two-way radios
If you operate two-way radios incorrectly in
the vehicle, the electromagnetic radiation
could interfere with the on-board electronics,
e.g.:
if the two-way radio is not connected to
R
an exterior aerial
if the exterior aerial is not correctly
R
mounted or is not of low reflection
This could jeopardise the operating safety of
the vehicle.
Have the low-reflection exterior aerial

When operating two-way radios in the
#
vehicle, always connect them to the
low-reflection exterior aerial.
