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.

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.
