▌Notes on installing two-way radios

WARNING Risk of accident due to

improper work on two-way radios

If two-way radios are manipulated or retrot-

ted incorrectly, the electromagnetic radiation

from the two-way radios can interfere with the

vehicle electronics and jeopardize the operat-

ing safety of the vehicle.

You should have all work on electrical

and electronic components carried out

at a qualied 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 particu-

lar:

The two-way radio is not connected to an

exterior antenna.

The exterior antenna is installed incor-

rectly or is not a low-reection antenna.

This could jeopardize the operating safety of

the vehicle.

Have the low-reection exterior antenna

installed at a qualied specialist work-

shop.

When operating two-way radios in the

vehicle, always connect them to the low-

reection exterior antenna.

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
