Chapter 8: Installation
• All Raytheon equipment and cables connected to it are
• 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 is supplied from a separate battery than that 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 may
cause the loss of some information and may change the mode of operation.
• Raytheon specified cables are 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 should not be
removed. If the ferrite has to be removed during installation it must be
reassembled in the same position. The Pathfinder Radar Scanner Owner's
Handbook includes instructions on fitting a ferrite.
• Ensure you follow the installation instructions in Sections 8.6 to 8.8,
particular with reference to earthing details.
The following illustration shows typical cable suppression ferrites fitted to
Raytheon equipment. Always use the ferrite specified by Raytheon.
If your Raytheon equipment is to be connected to other equipment using a cable
not supplied by Raytheon, a suppression ferrite MUST always be fitted to the
cable close to the Raytheon unit.
