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
For the reason of a high soundness level the mobile phone must be permanently connected 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 telephone is used, note that it can constantly transmit information to its base station, even when the telephone is not used. For this reason, it should not be placed beside electronic equipment in the machine, such as directly on a control panel etc.
Guidelines when installing aerial
The guide-lines given below must be followed during installation:
Q
Q The position of the aerial must be selected so that it is well adapted to the environment. The down lead from the aerial should be of the coaxial cable. 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.
Q
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 cable and the aerial to the communication equipment. Cables which may suffer from interference are cables to and from electronic units on the machine. Install cable harnesses as close to grounded plate surfaces as possible, as these have a screening effect.
