EMC Installation Guidelines

All Raytheon equipment and accessories are designed to the best

industry standards for use in the leisure marine environment.

Their design and manufacture conforms to the appropriate

Electromagnetic Compatibility (EMC) standards, but correct installation

is required to maintain EMC performance and CE compliance. Although

every effort has been taken to ensure that they will perform under all

conditions, it is important to understand what factors could affect the

operation of the product.

To avoid the risk of operating problems, all Raytheon equipment and

cables connected to it should be:

• At least 1m (3ft) from any equipment transmitting or cables carrying

radio signals e.g. VHF radios, cables and antennas. In the case of

SSB radios, the distance should be increased to 2m (7ft).

• More than 2m (7ft) from the path of a radar beam. A radar beam can

normally be assumed to spread 20 degrees above and below the

radiating element.

• The equipment should be supplied from a different battery than the

one used for engine start. Voltage drops below 10.7V in the power

supply to our products can cause the equipment to reset. This will not

damage the equipment, but will cause the loss of some information

and can change the mode of operation.

• Genuine Raytheon cables should be used at all times. Cutting and

rejoining these cables can compromise EMC performance and so

should be avoided unless doing so is detailed in this handbook.

• If a suppression ferrite is attached to a cable, this ferrite must not be

removed. If the ferrite has to be removed during installation it must be

reassembled in the same position.

The following illustration shows the range of suppression ferrites fitted to

Raytheon equipment.
