Communication equipment,
installation
IMPORTANT! All installation of optional communication
equipment must be carried out by trained professionals and
in accordance with the Volvo CE instructions applicable to
the machine.
Protection against electromagnetic
interference
This machine has been tested in accordance with EU directive
89/336/EEC governing electromagnetic interference. It is
therefore very important that all non-approved electronic
accessories, such as communication equipment, should be tested
before installation and use, since they can cause interference to
the electronic systems of the machine.
Mobile telephones
To obtain the best functionality, mobile telephones should be
permanently installed in the electrical system of the machine, with
a permanent aerial fixed on the cab and installed as advised by the
manufacturer. Note, that if a portable mobile telephone is used, it
can constantly transmit information to its base station, even when
the telephone is not used. For this reason, it must not be placed
close to other electronic equipment in the machine, e.g. directly on
a control panel or similar.
Guidelines
The guidelines given below must be followed during installation:
The position of the aerial must be selected so that it is well
adapted to the environment.
The aerial downlead must be of the coaxial cable type. Make
sure that the cable is undamaged, that the screen is not split up
at the ends, but thoroughly encased in the connector and has
a good galvanic contact with the same.
The mating surface between the aerial mounting bracket and
the bodywork must be clean metal surfaces, with all dirt and
oxide removed. Protect the mating surfaces against corrosion
after installation, to maintain good galvanic contact.
Remember to keep interfering cables and those which may
suffer from interference apart. Interfering cables are the power
supply cables and the aerial cable to the communication
equipment. Cables, which may suffer interference, run to and
from electronic control units on the machine. Install cable
harnesses as close to grounded plate surfaces as possible, as
these have a screening effect.
