Safety notices
Intended use
RayTech V6.0 is intended for recreational marine use. Users should note that
only authorized government charts and associated Notices to Mariners
contain all the information required for safe navigation
Disclaimers
This electronic chart is an aid to navigation designed to facilitate the use of
authorized government charts, not to replace them. Only official government
charts and notices to mariners contain all of the current information needed for
the safety of navigation, and the Captain is responsible for their prudent use.
WARNING
Navigation aid
When this product is used within a navigation system, it is
only an aid to navigation. It’s accuracy can be affected by
many factors, including equipment failure or defects, envi-
ronmental conditions and improper use or handling. It is
the user’s responsibility to exercise common prudence
and navigational judgements. This product should not be
relied upon as a substitute for such prudence and judge-
ment. Always maintain a permanent watch so that you can
respond to situations as they develop.
WARNING
Product installation
This equipment must be installed and operated in accor-
dance with the Raymarine instructions provided within
this guide. Failure to do so could result in poor product
performance, personal injury, and/or damage to your boat.
CAUTION
Navionics CF Card Reader
The Navionics CF card reader has been designed and
tested for home and dockside planning use only and has
not been tested to marine standards for ruggedness or
interference with other devices on board the vessel.
Raymarine cannot accept responsibility or liability for any
damage to the card reader, associated systems and equip-
ment or compatibility issues arising from its use while
underway.
2 RayTech RNS V6.0 - Users Guide
This program and its charts do not excuse the user from carrying the required
official charts and documents.
Raymarine does not warrant that this product is error free or that it is
compatible with products manufactured by any person or entity other than
Raymarine.
This product utilizes digital chart data, and electronic information from the
Global Positioning System (GPS) and weather information which may contain
errors. Raymarine does not warrant the accuracy of such information and you
are advised that errors in such information may cause the product to
malfunction or give incorrect readings. Raymarine is not responsible for
damages or injuries caused by your use or inability to use the product, by the
interaction of the product with products manufactured by others, or by errors in
chart data or information utilized by the product provided by third parties.
Except for the limited warranty regarding the magnetic media contained in the
license agreement accompanying the product, this product is provided ‘AS IS’
without warranty of any kind, either express or implied, including but not
limited to the implied warranties of merchantability and fitness for a particular
purpose, and any others which may arise from course of performance, course of
dealing, or usage of trade.
The limits of electronic navigation
Experienced navigators know not to rely on a single method of navigation for
determining their position. Two or more methods should be used to determine
position and guard against errors placing you or your boat in a dangerous
position. Global Positioning System (GPS) based electronic navigation is an
amazing application of technology, but like all other technology, has limits. A
wise navigator will understand these limits and how they affect the safety of
their boat and crew.
The Global Positioning System is made up of components starting with ground
based computers to monitor and maintain the system made up of 24 satellites
in orbit around the earth. The system ends at your boat’s receiver. Like all
systems it is not perfect and any part of it can fail. GPS accuracy varies between
2 and 50 meters.
NMEA 0183 1.0 / 1.5 only supports 2 digits of latitude and longitude, giving a
precision of approximately 60 feet.
NMEA 2.0 / 2.1 supports 3 digits of latitude and longitude, giving a precision of
approximately 6 feet.
Another limitation to the system accuracy is digital charts. These electronic
charts are made by highly skilled cartographers. Surveys on which the
cartography is based, were in some cases, made over 50 years ago. So despite
everyone’s best efforts, it may be possible to have errors in the final product.
Lastly, RayTech software was developed by highly skilled and talented software
engineers and underwent a rigorous test and quality assurance program before
being released. However, it is possible that software issues or malfunctions may
remain undetected in the software. While Raymarine make every effort to find,
fix and repair software issues as they are discovered, this product is specifically
not promised to be issue free.
About this manual
This manual describes how to install and operate RayTech V6.0 marine
navigation software. It assumes that the personal computer (PC) on which the
software is to be installed meets the requirements for running this version of
RayTech, and that all peripheral equipment intended to be operated with it is
compatible and has been correctly installed.
This manual is intended for users with varying technical and
marine abilities, but assumes a general level of knowledge of PC
use and nautical terminology and practices.
This manual gives an overview of RayTech V6.0, and details the main functions
and how to operate them. There are several ways that a task can be completed,
experiment, find the way of using RayTech that best suits your way of working.
