Handling
Keep this manual in a safe place where you can access it quickly.
The Global Positioning System (GPS) consists of a total 24 GPS satellites that orbit the earth,
enabling you to determine your position anywhere in the world, 24 hours a day, if you can receive
satellite signals. During actual navigation, carefully compare the position data with all available
navigation sources such as Loran C, Decca, other navigators, charts, visual navigation, depth, water
temperature and others. It is your responsibility to make navigation judgments.
DGPS Operation Note :
Your position can be improved by DGPS correction. However, when you are communicating with other
ships, you may use a DGPS corrected position but they may not. Make your position source known
during communication.
The Electronic Chart :
Only official authorized charts and notices to mariners contain all the information needed for the safety
of navigation and, as always remember, the user is responsible for their prudent use.
