•
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 radiat-
ing element.
•
The equipment is supplied from a separate battery from that used for
engine start. Voltage 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 ferrite 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.

Typical Suppression Ferrites
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.
