EMC servicing and safety guidelines

Raymarine equipment should be serviced only by authorized 
Raymarine service technicians. They will ensure that service 
procedures/ replacement parts used will not affect performance. 
There are no user serviceable parts in any Raymarine product.

Some products generate high voltages, so never handle the cables 
or connectors when power is being supplied to the equipment.

When powered up, all electrical equipment produces 
electromagnetic fields. These can cause adjacent pieces of 
electrical equipment to interact with one another, with a 
consequent adverse effect on operation. In order to minimize 
these effects and enable you to get the best possible performance 
from your Raymarine equipment, guidelines are given in the 
installation instructions, to enable you to ensure minimum 
interaction between different items of equipment, i.e. ensure 
optimum Electromagnetic Compatibility (EMC).

Always report any EMC-related problem to your nearest Raymarine 
dealer. We use such information to improve our quality standards.

In some installations, it may not be possible to prevent the 
equipment from being affected by external influences. In general 
this will not damage the equipment but it can lead to spurious 
resetting action, or momentarily may result in faulty operation.

Product support

Raymarine products are supported by a worldwide network of 
distributors and Authorized Service Representatives. If you 
encounter any difficulties with this product, please contact either 
your national distributor, service representative, or the Raymarine 
Technical Services Call Center
