CHAPTER 1: IMPORTANT INFORMATION

Safety warnings

Warning: Ensure safe navigation
This product is intended only as an aid to navigation and
must never be used in preference to sound navigational
judgment. Only official government charts and notices to
mariners contain all the current information needed for safe
navigation, and the captain is responsible for their prudent
use. It is the user's responsibility to use official government
charts, notices to mariners, caution and proper navigational
skill when operating this or any other Raymarine product.
Warning: Minimum Safe Depth, Width and
Height
Depending on cartography vendor, the [Minimum safe depth],
[Minimum safe width], and [Minimum safe height] settings that
you specify for your vessel will be used during automatic route
generation. These settings will ensure that automatic routes
are not generated in areas that are unsuitable for your vessel.
Minimum safe settings are user-defined calculations. As these
calculations are outside of Raymarine's control, Raymarine
will not be held liable for any damage, physical or otherwise,
resulting from the use of the automatic route generation
feature or the [Minimum safe depth], [Minimum safe width] or
[Minimum safe height] settings.
Warning: Maintain a permanent watch
Always maintain a permanent watch, this will allow you to
respond to situations as they develop. Failure to maintain a
permanent watch puts yourself, your vessel and others at
serious risk of harm.
Important information
Warning: Autopilot usage
Autopilots navigate a preset course and do NOT respond
to hazards automatically. The operator must remain at the
helm at all times and be ready to avoid hazards and warn
passengers of course changes.
Warning: Automatic route generation
• Do NOT rely on automatically generated routes to guarantee
that the route is safe to navigate. You MUST review the
suggested route carefully and where necessary edit the
route before following it.
• If a waypoint within any automatically generated route is
added or moved the Automatic route generation algorithm
will NOT be used, extra care should be taken to ensure that
the route leg and any moved waypoints are safe to navigate.
Warning: Traffic separation
Automatic route generation features do not adhere to the
Traffic Separation Schemes identified in Rule 10 of the
International Regulations for Preventing Collisions at Sea
1972 as amended.
Raymarine® therefore recommends that you do NOT use
Automatic route generation to create any part of a route
which will cross traffic lanes or pass near to traffic separation
lines. In these situations Automatic route generation MUST
be switched Off and the route or route leg MUST be built
manually, ensuring compliance to the rules laid out in the
above regulations.
Warning: Minimum Sonar Depth
Accurate bottom tracking can be unreliable in depths
shallower than 0.8 m/2.62 ft When operating at or below this
depth be cautious of misleading sonar returns or false bottom
tracking.
