• At least 3 ft (1 m) 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 7 ft (2 m).
• More than 7 ft (2 m) 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 from that used for engine start. Volt-
age drops below 10 V, and starter motor transients, can cause the equipment to reset. This
will not damage the equipment, but may cause the loss of some information and may
change the operating mode.
• Raymarine specified cables are used. Cutting and rejoining these cables can compromise
EMC performance and must be avoided unless doing so is detailed in the installation
manual.
• If a suppression ferrite is attached to a cable, this ferrite should not be removed. If the fer-
rite needs to be removed during installation it must be reassembled in the same position.
Suppression ferrites
The following illustration shows typical cable suppression ferrites used with Raymarine
equipment. Always use the ferrites supplied by Raymarine. This product has ferrites mounted
internally.

Connections to other equipment
If your Raymarine equipment is to be connected to other equipment using a cable not
supplied by Raymarine, a suppression ferrite MUST always be attached to the cable near to
the Raymarine unit.
