Raymarine DS400 and DS500 Digital Fishfinders are intended for 
recreational fishfinding.
EMC Conformance
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. 
More than 7 ft (2 m) from the path of a radar beam. A radar beam can nor-
mally be assumed to spread 20 degrees above and below the radiating ele-
ment.
