Communication equipment, installation

Communication equipment,
installation
IMPORTANT! Any installation of optional communication
equipment must be carried out by trained professionals and
in compliance with the instructions supplied by Volvo CE
with the machine.
Protection against electromagnetic interfe-
rence
This machine has been tested in accordance with EC directive 89/
336/EEC concerning 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 such equipment can cause interference with the
electronic systems of the machine.
Mobile phones
For a reliable function the mobile phone must be permanently con-
nected to the electrical system of the machine. Apart from that a
fixed aerial must be mounted to the outside of the machine, as
specified by the manufacturer. If a portable mobile phone is used,
you should bear in mind that it may constantly transmit information
to its base station, even when not used. For this reason, it should
not be placed next to electronic equipment in the machine, such as
directly on a control panel etc.
Guidelines
The guidelines specified below must be followed during
installation:
The position of the aerial should be chosen in such a way, that
it is well adapted to the environment.
The down lead from the aerial should be of 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 good galvanic contact with the same.
The mating surface between the aerial mounting bracket and
the bodywork must be free of dirt and oxides. After installation
protect the mating surfaces against corrosion, as a measure to
maintain good galvanic contact.
Remember to keep interfering cables away from cables
susceptible for interference. Interfering cables are the power supp-
ly cable and the aerial cable to the communication equipment. Ca-
bles susceptible for interference are cables to and from electronic
units on the machine. Install cable harnesses as close to grounded
plate surfaces as possible, since these have a screening effect.
