• Magnetic compass — refer to the Compass safe distance section in
this document for advice on maintaining a suitable distance between this
product and any compasses on your vessel.
• Power — to keep cable runs to a minimum, the product must be located
as close as possible to the vessel's dc power supply.
• Mounting surface — ensure the product is adequately supported on a
secure surface. Refer to the weight information provided in the Technical
specification for this product and ensure that the intended mounting

this distance should be at least 1 m (3.3 ft) in all directions. However for
some smaller vessels it may not be possible to locate the product this far
away from a compass. In this situation, when choosing the installation
location for your product, ensure that the compass is not affected by the
product when it is in a powered state.
