Notes on work on the engine electronics
* NOTE Premature wear through improper
maintenance
Improper maintenance may cause vehicle com-
ponents to wear more quickly and the vehicle's
operating permit may be invalidated.
Always have work on the engine elec-
#
tronics and related components carried
out at a qualified specialist workshop.
Two-way radios
▌Installation notes for two-way radios
& WARNING Risk of accident due to
improper work on two-way radios
If two-way radios are manipulated or retrofitted
incorrectly, the electromagnetic radiation from
the two-way radios can interfere with the vehi-
cle electronics and jeopardise the operating
safety of the vehicle.
You should have all work on electrical
#
and electronic components carried out
at a qualified specialist workshop.
& WARNING Risk of accident due to
improper operation of two-way radios
If you use two-way radios in the vehicle
improperly, their electromagnetic radiation can
disrupt the vehicle's electronics. This is the
case in the following situations, in particular:
The two-way radio is not connected to an
R
exterior aerial.
The exterior aerial is fitted incorrectly or is
R
not a low-reflection aerial.
This could jeopardise the operating safety of
the vehicle.
Have the low-reflection exterior aerial fit-
#
ted at a qualified specialist workshop.
When operating two-way radios in the
#
vehicle, always connect them to the low-
reflection exterior aerial.
* NOTE Invalidation of the operating permit
due to failure to comply with the instruc-
tions for installation and use
The operating permit may be invalidated if the
instructions for installation and use of two-way
radios are not observed.
Only use approved frequency bands.
#
Observe the maximum permissible out-
#
put power in these frequency bands.
Only use approved aerial positions.
#
Use Technical Specification ISO/TS 21609 (Road
Vehicles - EMC guidelines for installation of after-
market radio frequency transmitting equipment)
when retrofitting two-way radios. Comply with the
legal requirements for detachable parts.
If your vehicle has fittings for two-way radio equip-
ment, use the power supply or aerial connections
intended for use with the fittings. Observe the
manufacturer's supplements during installation.
▌Two-way radio transmission output
The maximum transmission outputs (PEAK) at the
base of the aerial must not exceed the values in
