1.
This location provides optimal GPS performance
(above decks).
2.
In this location, GPS performance may be less
effective.
3.
This location is NOT recommended for GPS
antenna.
Vessel construction
The construction of your vessel can have an impact
on GPS performance. For example, the proximity of
heavy structure such as a structural bulkhead, or the
interior of larger vessels may result in a reduced GPS
signal. Before locating equipment with an internal GPS
antenna below decks, seek professional assistance
and consider use of an external GPS antenna mounted
above decks.
Prevailing conditions
The weather and location of the vessel can affect the
GPS performance. Typically calm clear conditions
provide for a more accurate GPS fix. Vessels at
extreme northerly or southerly latitudes may also
receive a weaker GPS signal. GPS antenna mounted
below decks will be more susceptible to performance
issues related to the prevailing conditions.
Compass safe distance
To prevent potential interference with the vessel’s
magnetic compasses, ensure an adequate distance is
maintained from the display.
When choosing a suitable location for the multifunction
display you should aim to maintain the maximum
possible distance between the display and any
compasses. Typically this distance should be at least
1 m (3 ft) in all directions. However for some smaller
vessels it may not be possible to locate the display this
far away from a compass. In this situation, the following
figures provide the minimum safe distance that should
be maintained between the display and any compasses.

Viewing angle considerations
As display contrast, color and night mode performance
are all affected by the viewing angle, Raymarine
recommends you temporarily power up the display
when planning the installation, to enable you to best
judge which location gives the optimum viewing angle.
