Any moisture or water vapor in this area could cause damage by 
coming into contact with electrical connections, or condensation 
by entering the control unit through its breathing hole.
Cabling guidelines
•
consider how you will run cables to and from the control unit
•
avoid running cables through bilges where possible
•
avoid running cables close to fluorescent lights, engines, radio 
transmitting equipment etc.
EMC installation guidelines
All Raymarine equipment and accessories are designed to the best 
industry standards for use in the recreational marine environment.
Their design and manufacture conforms to the appropriate 
Electromagnetic Compatibility (EMC) standards, but correct 
installation is required to ensure that performance is not 
compromised. 
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.
The guidelines given here describe the conditions for optimum EMC 
performance, but it is recognized that it may not be possible to meet 
all of these conditions in all situations. To ensure the best possible 
conditions for EMC performance within the constraints imposed by 
any location, always ensure the maximum separation possible 
between different items of electrical equipment.
For optimum EMC performance, it is recommended that wherever 
possible:
•
Raymarine equipment and cables connected to it are:
•
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. Voltage drops below 10 V, and starter motor
