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 configuration is
essential 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 installed as follows:
• Ensuring you follow the installation instructions in Chapter 2, particularly
with reference to earthing details.
• With at least 1 m (3 ft) 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 2 m (7 ft).
• Avoiding the beam from another radar scanner. 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 10.7 V 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 must be used at all times. Cutting and rejoining
these cables can degrade EMC performance and must therefore be avoided
unless specifically 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. Section 2.1 Installing the Radome Scanner includes
instructions on fitting a ferrite.
The following illustration shows a typical range of suppression ferrites fitted to
Raytheon equipment.
