1. 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:
