Mounting - New A Series - Raymarine a65 Installation And Operation Instructions Manual

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.
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.
